Calling - conventions, function arguments, return values, struct sizes/defines and - more. - - For a longer description, see - http://en.wikipedia.org/wiki/Application_binary_interface - -Upgrades - - In the vast majority of all cases, a typical libcurl upgrade does not break - the ABI at all. Your application can remain using libcurl just as before, - only with less bugs and possibly with added new features. You need to read - the release notes, and if they mention an ABI break/soname bump, you may - have to verify that your application still builds fine and uses libcurl as - it now is defined to work. - -Version Numbers - - In libcurl land, you really can't tell by the libcurl version number if that - libcurl is binary compatible or not with another libcurl version. - -Soname Bumps - - Whenever there are changes done to the library that will cause an ABI - breakage, that may require your application to get attention or possibly be - changed to adhere to new things, we will bump the soname. Then the library - will get a different output name and thus can in fact be installed in - parallel with an older installed lib (on most systems). Thus, old - applications built against the previous ABI version will remain working and - using the older lib, while newer applications build and use the newer one. - - During the first seven years of libcurl releases, there have only been four - ABI breakages. - -Downgrades - - Going to an older libcurl version from one you're currently using can be a - tricky thing. Mostly we add features and options to newer libcurls as that - won't break ABI or hamper existing applications. This has the implication - that going backwards may get you in a situation where you pick a libcurl - that doesn't support the options your application needs. Or possibly you - even downgrade so far so you cross an ABI break border and thus a different - soname, and then your application may need to adapt to the modified ABI. - -History - - The previous major library soname number bumps (breaking backwards - compatibility) have happened the following times: - - 0 - libcurl 7.1, August 2000 - - 1 - libcurl 7.5 December 2000 - - 2 - libcurl 7.7 March 2001 - - 3 - libcurl 7.12.0 June 2004 - - 4 - libcurl 7.16.0 October 2006 diff --git a/plugins/FTPFileYM/curl/docs/libcurl/Makefile.am b/plugins/FTPFileYM/curl/docs/libcurl/Makefile.am deleted file mode 100644 index 3114e2b3b0..0000000000 --- a/plugins/FTPFileYM/curl/docs/libcurl/Makefile.am +++ /dev/null @@ -1,102 +0,0 @@ -#*************************************************************************** -# _ _ ____ _ -# Project ___| | | | _ \| | -# / __| | | | |_) | | -# | (__| |_| | _ <| |___ -# \___|\___/|_| \_\_____| -# -# Copyright (C) 1998 - 2012, Daniel Stenberg, <daniel@haxx.se>, et al. -# -# This software is licensed as described in the file COPYING, which -# you should have received as part of this distribution.

The -third argument \fBMUST\fP be a pointer to a long, a pointer to a char *, a -pointer to a struct curl_slist * or a pointer to a double (as this -documentation describes further down). The data pointed-to will be filled in -accordingly and can be relied upon only if the function returns CURLE_OK. Use -this function AFTER a performed transfer if you want to get transfer- oriented -data. - -You should not free the memory returned by this function unless it is -explicitly mentioned below. -.SH AVAILABLE INFORMATION -The following information can be extracted: -.IP CURLINFO_EFFECTIVE_URL -Pass a pointer to a char pointer to receive the last used effective URL. -.IP CURLINFO_RESPONSE_CODE -Pass a pointer to a long to receive the last received HTTP, FTP or SMTP -response code. This option was previously known as CURLINFO_HTTP_CODE in -libcurl 7.10.7 and earlier. The value will be zero if no server response code -has been received. Note that a proxy's CONNECT response should be read with -\fICURLINFO_HTTP_CONNECTCODE\fP and not this. - -Support for SMTP responses added in 7.25.0. -.IP CURLINFO_HTTP_CONNECTCODE -Pass a pointer to a long to receive the last received proxy response code to a -CONNECT request. -.IP CURLINFO_FILETIME -Pass a pointer to a long to receive the remote time of the retrieved document -(in number of seconds since 1 jan 1970 in the GMT/UTC time zone). If you get --1, it can be because of many reasons (unknown, the server hides it or the -server doesn't support the command that tells document time etc) and the time -of the document is unknown. Note that you must tell the server to collect this -information before the transfer is made, by using the CURLOPT_FILETIME option -to \fIcurl_easy_setopt(3)\fP or you will unconditionally get a -1 back. (Added -in 7.5) -.IP CURLINFO_TOTAL_TIME -Pass a pointer to a double to receive the total time in seconds for the -previous transfer, including name resolving, TCP connect etc. -.IP CURLINFO_NAMELOOKUP_TIME -Pass a pointer to a double to receive the time, in seconds, it took from the -start until the name resolving was completed. -.IP CURLINFO_CONNECT_TIME -Pass a pointer to a double to receive the time, in seconds, it took from the -start until the connect to the remote host (or proxy) was completed. -.IP CURLINFO_APPCONNECT_TIME -Pass a pointer to a double to receive the time, in seconds, it took from the -start until the SSL/SSH connect/handshake to the remote host was completed. -This time is most often very near to the PRETRANSFER time, except for cases -such as HTTP pippelining where the pretransfer time can be delayed due to -waits in line for the pipeline and more. (Added in 7.19.0) -.IP CURLINFO_PRETRANSFER_TIME -Pass a pointer to a double to receive the time, in seconds, it took from the -start until the file transfer is just about to begin. This includes all -pre-transfer commands and negotiations that are specific to the particular -protocol(s) involved. It does \fInot\fP involve the sending of the protocol- -specific request that triggers a transfer. -.IP CURLINFO_STARTTRANSFER_TIME -Pass a pointer to a double to receive the time, in seconds, it took from the -start until the first byte is received by libcurl. This includes -CURLINFO_PRETRANSFER_TIME and also the time the server needs to calculate the -result. -.IP CURLINFO_REDIRECT_TIME -Pass a pointer to a double to receive the total time, in seconds, it took for -all redirection steps include name lookup, connect, pretransfer and transfer -before final transaction was started. CURLINFO_REDIRECT_TIME contains the -complete execution time for multiple redirections. (Added in 7.9.7) -.IP CURLINFO_REDIRECT_COUNT -Pass a pointer to a long to receive the total number of redirections that were -actually followed. (Added in 7.9.7) -.IP CURLINFO_REDIRECT_URL -Pass a pointer to a char pointer to receive the URL a redirect \fIwould\fP -take you to if you would enable CURLOPT_FOLLOWLOCATION. This can come very -handy if you think using the built-in libcurl redirect logic isn't good enough -for you but you would still prefer to avoid implementing all the magic of -figuring out the new URL. (Added in 7.18.2) -.IP CURLINFO_SIZE_UPLOAD -Pass a pointer to a double to receive the total amount of bytes that were -uploaded. -.IP CURLINFO_SIZE_DOWNLOAD -Pass a pointer to a double to receive the total amount of bytes that were -downloaded. The amount is only for the latest transfer and will be reset again -for each new transfer. -.IP CURLINFO_SPEED_DOWNLOAD -Pass a pointer to a double to receive the average download speed that curl -measured for the complete download. Measured in bytes/second. -.IP CURLINFO_SPEED_UPLOAD -Pass a pointer to a double to receive the average upload speed that curl -measured for the complete upload. Measured in bytes/second. -.IP CURLINFO_HEADER_SIZE -Pass a pointer to a long to receive the total size of all the headers -received. Measured in number of bytes. -.IP CURLINFO_REQUEST_SIZE -Pass a pointer to a long to receive the total size of the issued -requests. This is so far only for HTTP requests. Note that this may be more -than one request if FOLLOWLOCATION is true. -.IP CURLINFO_SSL_VERIFYRESULT -Pass a pointer to a long to receive the result of the certification -verification that was requested (using the CURLOPT_SSL_VERIFYPEER option to -\fIcurl_easy_setopt(3)\fP). -.IP CURLINFO_SSL_ENGINES -Pass the address of a 'struct curl_slist *' to receive a linked-list of -OpenSSL crypto-engines supported. Note that engines are normally implemented -in separate dynamic libraries. Hence not all the returned engines may be -available at run-time. \fBNOTE:\fP you must call \fIcurl_slist_free_all(3)\fP -on the list pointer once you're done with it, as libcurl will not free the -data for you. (Added in 7.12.3) -.IP CURLINFO_CONTENT_LENGTH_DOWNLOAD -Pass a pointer to a double to receive the content-length of the download. This -is the value read from the Content-Length: field. Since 7.19.4, this returns -1 -if the size isn't known. -.IP CURLINFO_CONTENT_LENGTH_UPLOAD -Pass a pointer to a double to receive the specified size of the upload. Since -7.19.4, this returns -1 if the size isn't known. -.IP CURLINFO_CONTENT_TYPE -Pass a pointer to a char pointer to receive the content-type of the downloaded -object. This is the value read from the Content-Type: field. If you get NULL, -it means that the server didn't send a valid Content-Type header or that the -protocol used doesn't support this. -.IP CURLINFO_PRIVATE -Pass a pointer to a char pointer to receive the pointer to the private data -associated with the curl handle (set with the CURLOPT_PRIVATE option to -\fIcurl_easy_setopt(3)\fP). Please note that for internal reasons, the -value is returned as a char pointer, although effectively being a 'void *'. -(Added in 7.10.3) -.IP CURLINFO_HTTPAUTH_AVAIL -Pass a pointer to a long to receive a bitmask indicating the authentication -method(s) available. The meaning of the bits is explained in the -CURLOPT_HTTPAUTH option for \fIcurl_easy_setopt(3)\fP. (Added in 7.10.8) -.IP CURLINFO_PROXYAUTH_AVAIL -Pass a pointer to a long to receive a bitmask indicating the authentication -method(s) available for your proxy authentication. (Added in 7.10.8) -.IP CURLINFO_OS_ERRNO -Pass a pointer to a long to receive the errno variable from a connect failure. -Note that the value is only set on failure, it is not reset upon a -successful operation. (Added in 7.12.2) -.IP CURLINFO_NUM_CONNECTS -Pass a pointer to a long to receive how many new connections libcurl had to -create to achieve the previous transfer (only the successful connects are -counted). Combined with \fICURLINFO_REDIRECT_COUNT\fP you are able to know -how many times libcurl successfully reused existing connection(s) or not. See -the Connection Options of \fIcurl_easy_setopt(3)\fP to see how libcurl tries -to make persistent connections to save time. (Added in 7.12.3) -.IP CURLINFO_PRIMARY_IP -Pass a pointer to a char pointer to receive the pointer to a zero-terminated -string holding the IP address of the most recent connection done with this -\fBcurl\fP handle. This string may be IPv6 if that's enabled. Note that you -get a pointer to a memory area that will be re-used at next request so you -need to copy the string if you want to keep the information. (Added in 7.19.0) -.IP CURLINFO_PRIMARY_PORT -Pass a pointer to a long to receive the destination port of the most recent -connection done with this \fBcurl\fP handle. (Added in 7.21.0) -.IP CURLINFO_LOCAL_IP -Pass a pointer to a char pointer to receive the pointer to a zero-terminated -string holding the local (source) IP address of the most recent connection done -with this \fBcurl\fP handle. This string may be IPv6 if that's enabled. The -same restrictions apply as to \fICURLINFO_PRIMARY_IP\fP. (Added in 7.21.0) -.IP CURLINFO_LOCAL_PORT -Pass a pointer to a long to receive the local (source) port of the most recent -connection done with this \fBcurl\fP handle. (Added in 7.21.0) -.IP CURLINFO_COOKIELIST -Pass a pointer to a 'struct curl_slist *' to receive a linked-list of all -cookies cURL knows (expired ones, too). Don't forget to -\fIcurl_slist_free_all(3)\fP the list after it has been used. If there are no -cookies (cookies for the handle have not been enabled or simply none have been -received) 'struct curl_slist *' will be set to point to NULL. (Added in -7.14.1) -.IP CURLINFO_LASTSOCKET -Pass a pointer to a long to receive the last socket used by this curl -session. If the socket is no longer valid, -1 is returned. When you finish -working with the socket, you must call curl_easy_cleanup() as usual and let -libcurl close the socket and cleanup other resources associated with the -handle. This is typically used in combination with \fICURLOPT_CONNECT_ONLY\fP. -(Added in 7.15.2) - -NOTE: this API is not really working on win64, since the SOCKET type on win64 -is 64 bit large while its 'long' is only 32 bits. -.IP CURLINFO_FTP_ENTRY_PATH -Pass a pointer to a char pointer to receive a pointer to a string holding the -path of the entry path. That is the initial path libcurl ended up in when -logging on to the remote FTP server. This stores a NULL as pointer if -something is wrong. (Added in 7.15.4) - -Also works for SFTP since 7.21.4 -.IP CURLINFO_CERTINFO -Pass a pointer to a 'struct curl_certinfo *' and you'll get it set to point to -struct that holds a number of linked lists with info about the certificate -chain, assuming you had CURLOPT_CERTINFO enabled when the previous request was -done. The struct reports how many certs it found and then you can extract info -for each of those certs by following the linked lists.

By using the -appropriate options to \fIcurl_easy_setopt\fP, you can change libcurl's -behavior. All options are set with the \fIoption\fP followed by a -\fIparameter\fP. That parameter can be a \fBlong\fP, a \fBfunction pointer\fP, -an \fBobject pointer\fP or a \fBcurl_off_t\fP, depending on what the specific -option expects. Read this manual carefully as bad input values may cause -libcurl to behave badly! You can only set one option in each function call. A -typical application uses many curl_easy_setopt() calls in the setup phase. - -Options set with this function call are valid for all forthcoming transfers -performed using this \fIhandle\fP. The options are not in any way reset -between transfers, so if you want subsequent transfers with different options, -you must change them between the transfers. You can optionally reset all -options back to internal default with \fIcurl_easy_reset(3)\fP. - -Strings passed to libcurl as 'char *' arguments, are copied by the library; -thus the string storage associated to the pointer argument may be overwritten -after curl_easy_setopt() returns. Exceptions to this rule are described in -the option details below. - -Before version 7.17.0, strings were not copied. Instead the user was forced -keep them available until libcurl no longer needed them. - -The \fIhandle\fP is the return code from a \fIcurl_easy_init(3)\fP or -\fIcurl_easy_duphandle(3)\fP call. -.SH BEHAVIOR OPTIONS -.IP CURLOPT_VERBOSE -Set the parameter to 1 to get the library to display a lot of verbose -information about its operations. Very useful for libcurl and/or protocol -debugging and understanding. The verbose information will be sent to stderr, -or the stream set with \fICURLOPT_STDERR\fP. - -You hardly ever want this set in production use, you will almost always want -this when you debug/report problems. Another neat option for debugging is the -\fICURLOPT_DEBUGFUNCTION\fP. -.IP CURLOPT_HEADER -A parameter set to 1 tells the library to include the header in the body -output. This is only relevant for protocols that actually have headers -preceding the data (like HTTP). -.IP CURLOPT_NOPROGRESS -Pass a long. If set to 1, it tells the library to shut off the progress meter -completely. It will also prevent the \fICURLOPT_PROGRESSFUNCTION\fP from -getting called. - -Future versions of libcurl are likely to not have any built-in progress meter -at all. -.IP CURLOPT_NOSIGNAL -Pass a long. If it is 1, libcurl will not use any functions that -install signal handlers or any functions that cause signals to be sent to the -process. This option is mainly here to allow multi-threaded unix applications -to still set/use all timeout options etc, without risking getting signals. -(Added in 7.10) - -If this option is set and libcurl has been built with the standard name -resolver, timeouts will not occur while the name resolve takes place. -Consider building libcurl with c-ares support to enable asynchronous DNS -lookups, which enables nice timeouts for name resolves without signals. - -Setting \fICURLOPT_NOSIGNAL\fP to 1 makes libcurl NOT ask the system to ignore -SIGPIPE signals, which otherwise are sent by the system when trying to send -data to a socket which is closed in the other end. libcurl makes an effort to -never cause such SIGPIPEs to trigger, but some operating systems have no way -to avoid them and even on those that have there are some corner cases when -they may still happen, contrary to our desire. In addition, using -\fICURLAUTH_NTLM_WB\fP authentication could cause a SIGCHLD signal to be -raised. -.IP CURLOPT_WILDCARDMATCH -Set this option to 1 if you want to transfer multiple files according to a -file name pattern. The pattern can be specified as part of the -\fICURLOPT_URL\fP option, using an fnmatch-like pattern (Shell Pattern -Matching) in the last part of URL (file name). - -By default, libcurl uses its internal wildcard matching implementation. You -can provide your own matching function by the \fICURLOPT_FNMATCH_FUNCTION\fP -option. - -This feature is only supported by the FTP download for now. - -A brief introduction of its syntax follows: -.RS -.IP "* - ASTERISK" -\&ftp://example.com/some/path/\fB*.txt\fP (for all txt's from the root -directory) -.RE -.RS -.IP "? - QUESTION MARK" -Question mark matches any (exactly one) character. - -\&ftp://example.com/some/path/\fBphoto?.jpeg\fP -.RE -.RS -.IP "[ - BRACKET EXPRESSION" -The left bracket opens a bracket expression. The question mark and asterisk have -no special meaning in a bracket expression. Each bracket expression ends by the -right bracket and matches exactly one character. Some examples follow: - -\fB[a-zA-Z0\-9]\fP or \fB[f\-gF\-G]\fP \- character interval - -\fB[abc]\fP - character enumeration - -\fB[^abc]\fP or \fB[!abc]\fP - negation - -\fB[[:\fP\fIname\fP\fB:]]\fP class expression. Supported classes are -\fBalnum\fP,\fBlower\fP, \fBspace\fP, \fBalpha\fP, \fBdigit\fP, \fBprint\fP, -\fBupper\fP, \fBblank\fP, \fBgraph\fP, \fBxdigit\fP. - -\fB[][-!^]\fP - special case \- matches only '\-', ']', '[', '!' or '^'. These -characters have no special purpose. - -\fB[\\[\\]\\\\]\fP - escape syntax. Matches '[', ']' or '\\'. - -Using the rules above, a file name pattern can be constructed: - -\&ftp://example.com/some/path/\fB[a-z[:upper:]\\\\].jpeg\fP -.RE -.PP -(This was added in 7.21.0) -.SH CALLBACK OPTIONS -.IP CURLOPT_WRITEFUNCTION -Pass a pointer to a function that matches the following prototype: -\fBsize_t function( char *ptr, size_t size, size_t nmemb, void *userdata);\fP -This function gets called by libcurl as soon as there is data received that -needs to be saved. The size of the data pointed to by \fIptr\fP is \fIsize\fP -multiplied with \fInmemb\fP, it will not be zero terminated. Return the number -of bytes actually taken care of. If that amount differs from the amount passed -to your function, it'll signal an error to the library. This will abort the -transfer and return \fICURLE_WRITE_ERROR\fP. - -From 7.18.0, the function can return CURL_WRITEFUNC_PAUSE which then will -cause writing to this connection to become paused. See -\fIcurl_easy_pause(3)\fP for further details. - -This function may be called with zero bytes data if the transferred file is -empty. - -Set this option to NULL to get the internal default function. The internal -default function will write the data to the FILE * given with -\fICURLOPT_WRITEDATA\fP. - -Set the \fIuserdata\fP argument with the \fICURLOPT_WRITEDATA\fP option. - -The callback function will be passed as much data as possible in all invokes, -but you cannot possibly make any assumptions. It may be one byte, it may be -thousands. The maximum amount of body data that can be passed to the write -callback is defined in the curl.h header file: CURL_MAX_WRITE_SIZE (the usual -default is 16K). If you however have \fICURLOPT_HEADER\fP set, which sends -header data to the write callback, you can get up to -\fICURL_MAX_HTTP_HEADER\fP bytes of header data passed into it. This usually -means 100K. -.IP CURLOPT_WRITEDATA -Data pointer to pass to the file write function. If you use the -\fICURLOPT_WRITEFUNCTION\fP option, this is the pointer you'll get as -input. If you don't use a callback, you must pass a 'FILE *' as libcurl will -pass this to fwrite() when writing data. - -The internal \fICURLOPT_WRITEFUNCTION\fP will write the data to the FILE * -given with this option, or to stdout if this option hasn't been set. - -If you're using libcurl as a win32 DLL, you \fBMUST\fP use the -\fICURLOPT_WRITEFUNCTION\fP if you set this option or you will experience -crashes. - -This option is also known with the older name \fICURLOPT_FILE\fP, the name -\fICURLOPT_WRITEDATA\fP was introduced in 7.9.7. -.IP CURLOPT_READFUNCTION -Pass a pointer to a function that matches the following prototype: -\fBsize_t function( void *ptr, size_t size, size_t nmemb, void *userdata);\fP -This function gets called by libcurl as soon as it needs to read data in order -to send it to the peer. The data area pointed at by the pointer \fIptr\fP may -be filled with at most \fIsize\fP multiplied with \fInmemb\fP number of -bytes. Your function must return the actual number of bytes that you stored in -that memory area. Returning 0 will signal end-of-file to the library and cause -it to stop the current transfer. - -If you stop the current transfer by returning 0 "pre-maturely" (i.e before the -server expected it, like when you've said you will upload N bytes and you -upload less than N bytes), you may experience that the server "hangs" waiting -for the rest of the data that won't come. - -The read callback may return \fICURL_READFUNC_ABORT\fP to stop the current -operation immediately, resulting in a \fICURLE_ABORTED_BY_CALLBACK\fP error -code from the transfer (Added in 7.12.1) - -From 7.18.0, the function can return CURL_READFUNC_PAUSE which then will cause -reading from this connection to become paused. See \fIcurl_easy_pause(3)\fP -for further details. - -\fBBugs\fP: when doing TFTP uploads, you must return the exact amount of data -that the callback wants, or it will be considered the final packet by the -server end and the transfer will end there. - -If you set this callback pointer to NULL, or don't set it at all, the default -internal read function will be used. It is doing an fread() on the FILE * -userdata set with \fICURLOPT_READDATA\fP. -.IP CURLOPT_READDATA -Data pointer to pass to the file read function. If you use the -\fICURLOPT_READFUNCTION\fP option, this is the pointer you'll get as input. If -you don't specify a read callback but instead rely on the default internal -read function, this data must be a valid readable FILE *. - -If you're using libcurl as a win32 DLL, you MUST use a -\fICURLOPT_READFUNCTION\fP if you set this option. - -This option was also known by the older name \fICURLOPT_INFILE\fP, the name -\fICURLOPT_READDATA\fP was introduced in 7.9.7. -.IP CURLOPT_IOCTLFUNCTION -Pass a pointer to a function that matches the following prototype: -\fBcurlioerr function(CURL *handle, int cmd, void *clientp);\fP. This function -gets called by libcurl when something special I/O-related needs to be done -that the library can't do by itself. For now, rewinding the read data stream -is the only action it can request. The rewinding of the read data stream may -be necessary when doing a HTTP PUT or POST with a multi-pass authentication -method. (Option added in 7.12.3). - -Use \fICURLOPT_SEEKFUNCTION\fP instead to provide seeking! -.IP CURLOPT_IOCTLDATA -Pass a pointer that will be untouched by libcurl and passed as the 3rd -argument in the ioctl callback set with \fICURLOPT_IOCTLFUNCTION\fP. (Option -added in 7.12.3) -.IP CURLOPT_SEEKFUNCTION -Pass a pointer to a function that matches the following prototype: \fBint -function(void *instream, curl_off_t offset, int origin);\fP This function gets -called by libcurl to seek to a certain position in the input stream and can be -used to fast forward a file in a resumed upload (instead of reading all -uploaded bytes with the normal read function/callback). It is also called to -rewind a stream when doing a HTTP PUT or POST with a multi-pass authentication -method. The function shall work like "fseek" or "lseek" and accepted SEEK_SET, -SEEK_CUR and SEEK_END as argument for origin, although (in 7.18.0) libcurl -only passes SEEK_SET. The callback must return 0 (CURL_SEEKFUNC_OK) on -success, 1 (CURL_SEEKFUNC_FAIL) to cause the upload operation to fail or 2 -(CURL_SEEKFUNC_CANTSEEK) to indicate that while the seek failed, libcurl is -free to work around the problem if possible. The latter can sometimes be done -by instead reading from the input or similar. - -If you forward the input arguments directly to "fseek" or "lseek", note that -the data type for \fIoffset\fP is not the same as defined for curl_off_t on -many systems! (Option added in 7.18.0) -.IP CURLOPT_SEEKDATA -Data pointer to pass to the file seek function. If you use the -\fICURLOPT_SEEKFUNCTION\fP option, this is the pointer you'll get as input. If -you don't specify a seek callback, NULL is passed. (Option added in 7.18.0) -.IP CURLOPT_SOCKOPTFUNCTION -Pass a pointer to a function that matches the following prototype: \fBint -function(void *clientp, curl_socket_t curlfd, curlsocktype purpose);\fP. This -function gets called by libcurl after the socket() call but before the -connect() call. The callback's \fIpurpose\fP argument identifies the exact -purpose for this particular socket: - -\fICURLSOCKTYPE_IPCXN\fP for actively created connections or since 7.28.0 -\fICURLSOCKTYPE_ACCEPT\fP for FTP when the connection was setup with PORT/EPSV -(in earlier versions these sockets weren't passed to this callback). - -Future versions of libcurl may support more purposes. It passes the newly -created socket descriptor so additional setsockopt() calls can be done at the -user's discretion. Return 0 (zero) from the callback on success. Return 1 -from the callback function to signal an unrecoverable error to the library and -it will close the socket and return \fICURLE_COULDNT_CONNECT\fP. (Option -added in 7.16.0) - -Added in 7.21.5, the callback function may return -\fICURL_SOCKOPT_ALREADY_CONNECTED\fP, which tells libcurl that the socket is -in fact already connected and then libcurl will not attempt to connect it. -.IP CURLOPT_SOCKOPTDATA -Pass a pointer that will be untouched by libcurl and passed as the first -argument in the sockopt callback set with \fICURLOPT_SOCKOPTFUNCTION\fP. -(Option added in 7.16.0) -.IP CURLOPT_OPENSOCKETFUNCTION -Pass a pointer to a function that matches the following prototype: -\fBcurl_socket_t function(void *clientp, curlsocktype purpose, struct -curl_sockaddr *address);\fP. This function gets called by libcurl instead of -the \fIsocket(2)\fP call. The callback's \fIpurpose\fP argument identifies the -exact purpose for this particular socket: \fICURLSOCKTYPE_IPCXN\fP is for IP -based connections. Future versions of libcurl may support more purposes. It -passes the resolved peer address as a \fIaddress\fP argument so the callback -can modify the address or refuse to connect at all. The callback function -should return the socket or \fICURL_SOCKET_BAD\fP in case no connection could -be established or another error was detected. Any additional -\fIsetsockopt(2)\fP calls can be done on the socket at the user's discretion. -\fICURL_SOCKET_BAD\fP return value from the callback function will signal an -unrecoverable error to the library and it will return -\fICURLE_COULDNT_CONNECT\fP. This return code can be used for IP address -blacklisting. The default behavior is: -.nf - return socket(addr->family, addr->socktype, addr->protocol); -.fi -(Option added in 7.17.1.) -.IP CURLOPT_OPENSOCKETDATA -Pass a pointer that will be untouched by libcurl and passed as the first -argument in the opensocket callback set with \fICURLOPT_OPENSOCKETFUNCTION\fP. -(Option added in 7.17.1.) -.IP CURLOPT_CLOSESOCKETFUNCTION -Pass a pointer to a function that matches the following prototype: \fBint -function(void *clientp, curl_socket_t item);\fP. This function gets called by -libcurl instead of the \fIclose(3)\fP or \fIclosesocket(3)\fP call when -sockets are closed (not for any other file descriptors). This is pretty much -the reverse to the \fICURLOPT_OPENSOCKETFUNCTION\fP option. Return 0 to signal -success and 1 if there was an error. (Option added in 7.21.7) -.IP CURLOPT_CLOSESOCKETDATA -Pass a pointer that will be untouched by libcurl and passed as the first -argument in the closesocket callback set with -\fICURLOPT_CLOSESOCKETFUNCTION\fP. (Option added in 7.21.7) -.IP CURLOPT_PROGRESSFUNCTION -Pass a pointer to a function that matches the following prototype: \fBint -function(void *clientp, double dltotal, double dlnow, double ultotal, double -ulnow); \fP. This function gets called by libcurl instead of its internal -equivalent with a frequent interval during operation (roughly once per second -or sooner) no matter if data is being transferred or not. Unknown/unused -argument values passed to the callback will be set to zero (like if you only -download data, the upload size will remain 0). Returning a non-zero value from -this callback will cause libcurl to abort the transfer and return -\fICURLE_ABORTED_BY_CALLBACK\fP. - -If you transfer data with the multi interface, this function will not be -called during periods of idleness unless you call the appropriate libcurl -function that performs transfers. - -\fICURLOPT_NOPROGRESS\fP must be set to 0 to make this function actually -get called. -.IP CURLOPT_PROGRESSDATA -Pass a pointer that will be untouched by libcurl and passed as the first -argument in the progress callback set with \fICURLOPT_PROGRESSFUNCTION\fP. -.IP CURLOPT_HEADERFUNCTION -Pass a pointer to a function that matches the following prototype: -\fBsize_t function( void *ptr, size_t size, size_t nmemb, void -*userdata);\fP. This function gets called by libcurl as soon as it has -received header data. The header callback will be called once for each header -and only complete header lines are passed on to the callback. Parsing headers -is very easy using this. The size of the data pointed to by \fIptr\fP is -\fIsize\fP multiplied with \fInmemb\fP. Do not assume that the header line is -zero terminated! The pointer named \fIuserdata\fP is the one you set with the -\fICURLOPT_WRITEHEADER\fP option. The callback function must return the number -of bytes actually taken care of. If that amount differs from the amount passed -to your function, it'll signal an error to the library. This will abort the -transfer and return \fICURL_WRITE_ERROR\fP. - -A complete HTTP header that is passed to this function can be up to -\fICURL_MAX_HTTP_HEADER\fP (100K) bytes. - -If this option is not set, or if it is set to NULL, but -\fICURLOPT_HEADERDATA\fP (\fICURLOPT_WRITEHEADER\fP) is set to anything but -NULL, the function used to accept response data will be used instead. That is, -it will be the function specified with \fICURLOPT_WRITEFUNCTION\fP, or if it -is not specified or NULL - the default, stream-writing function. - -It's important to note that the callback will be invoked for the headers of -all responses received after initiating a request and not just the final -response. This includes all responses which occur during authentication -negotiation. If you need to operate on only the headers from the final -response, you will need to collect headers in the callback yourself and use -HTTP status lines, for example, to delimit response boundaries. - -When a server sends a chunked encoded transfer, it may contain a trailer. That -trailer is identical to a HTTP header and if such a trailer is received it is -passed to the application using this callback as well. There are several ways -to detect it being a trailer and not an ordinary header: 1) it comes after the -response-body. 2) it comes after the final header line (CR LF) 3) a Trailer: -header among the regular response-headers mention what header(s) to expect in -the trailer. - -For non-HTTP protocols like FTP, POP3, IMAP and SMTP this function will get -called with the server responses to the commands that libcurl sends. -.IP CURLOPT_WRITEHEADER -(This option is also known as \fBCURLOPT_HEADERDATA\fP) Pass a pointer to be -used to write the header part of the received data to. If you don't use -\fICURLOPT_WRITEFUNCTION\fP or \fICURLOPT_HEADERFUNCTION\fP to take care of -the writing, this must be a valid FILE * as the internal default will then be -a plain fwrite(). See also the \fICURLOPT_HEADERFUNCTION\fP option above on -how to set a custom get-all-headers callback. -.IP CURLOPT_DEBUGFUNCTION -Pass a pointer to a function that matches the following prototype: \fBint -curl_debug_callback (CURL *, curl_infotype, char *, size_t, void *);\fP -\fICURLOPT_DEBUGFUNCTION\fP replaces the standard debug function used when -\fICURLOPT_VERBOSE \fP is in effect. This callback receives debug information, -as specified with the \fBcurl_infotype\fP argument. This function must return -0. The data pointed to by the char * passed to this function WILL NOT be zero -terminated, but will be exactly of the size as told by the size_t argument. - -Available curl_infotype values: -.RS -.IP CURLINFO_TEXT -The data is informational text. -.IP CURLINFO_HEADER_IN -The data is header (or header-like) data received from the peer. -.IP CURLINFO_HEADER_OUT -The data is header (or header-like) data sent to the peer. -.IP CURLINFO_DATA_IN -The data is protocol data received from the peer. -.IP CURLINFO_DATA_OUT -The data is protocol data sent to the peer. -.RE -.IP CURLOPT_DEBUGDATA -Pass a pointer to whatever you want passed in to your -\fICURLOPT_DEBUGFUNCTION\fP in the last void * argument. This pointer is not -used by libcurl, it is only passed to the callback. -.IP CURLOPT_SSL_CTX_FUNCTION -This option does only function for libcurl powered by OpenSSL. If libcurl was -built against another SSL library, this functionality is absent. - -Pass a pointer to a function that matches the following prototype: -\fBCURLcode sslctxfun(CURL *curl, void *sslctx, void *parm);\fP This function -gets called by libcurl just before the initialization of a SSL connection -after having processed all other SSL related options to give a last chance to -an application to modify the behaviour of openssl's ssl initialization. The -\fIsslctx\fP parameter is actually a pointer to an openssl \fISSL_CTX\fP. If -an error is returned no attempt to establish a connection is made and the -perform operation will return the error code from this callback function. Set -the \fIparm\fP argument with the \fICURLOPT_SSL_CTX_DATA\fP option. This -option was introduced in 7.11.0. - -This function will get called on all new connections made to a server, during -the SSL negotiation. The SSL_CTX pointer will be a new one every time. - -To use this properly, a non-trivial amount of knowledge of the openssl -libraries is necessary. For example, using this function allows you to use -openssl callbacks to add additional validation code for certificates, and even -to change the actual URI of a HTTPS request (example used in the lib509 test -case). See also the example section for a replacement of the key, certificate -and trust file settings. -.IP CURLOPT_SSL_CTX_DATA -Data pointer to pass to the ssl context callback set by the option -\fICURLOPT_SSL_CTX_FUNCTION\fP, this is the pointer you'll get as third -parameter, otherwise \fBNULL\fP. (Added in 7.11.0) -.IP CURLOPT_CONV_TO_NETWORK_FUNCTION -.IP CURLOPT_CONV_FROM_NETWORK_FUNCTION -.IP CURLOPT_CONV_FROM_UTF8_FUNCTION -Pass a pointer to a function that matches the following prototype: -\fBCURLcode function(char *ptr, size_t length);\fP - -These three options apply to non-ASCII platforms only. They are available -only if \fBCURL_DOES_CONVERSIONS\fP was defined when libcurl was built. When -this is the case, \fIcurl_version_info(3)\fP will return the CURL_VERSION_CONV -feature bit set. - -The data to be converted is in a buffer pointed to by the ptr parameter. The -amount of data to convert is indicated by the length parameter. The converted -data overlays the input data in the buffer pointed to by the ptr parameter. -CURLE_OK should be returned upon successful conversion. A CURLcode return -value defined by curl.h, such as CURLE_CONV_FAILED, should be returned if an -error was encountered. - -\fBCURLOPT_CONV_TO_NETWORK_FUNCTION\fP and -\fBCURLOPT_CONV_FROM_NETWORK_FUNCTION\fP convert between the host encoding and -the network encoding. They are used when commands or ASCII data are -sent/received over the network. - -\fBCURLOPT_CONV_FROM_UTF8_FUNCTION\fP is called to convert from UTF8 into the -host encoding. It is required only for SSL processing. - -If you set a callback pointer to NULL, or don't set it at all, the built-in -libcurl iconv functions will be used. If HAVE_ICONV was not defined when -libcurl was built, and no callback has been established, conversion will -return the CURLE_CONV_REQD error code. - -If HAVE_ICONV is defined, CURL_ICONV_CODESET_OF_HOST must also be defined. -For example: - - \&#define CURL_ICONV_CODESET_OF_HOST "IBM-1047" - -The iconv code in libcurl will default the network and UTF8 codeset names as -follows: - - \&#define CURL_ICONV_CODESET_OF_NETWORK "ISO8859-1" - - \&#define CURL_ICONV_CODESET_FOR_UTF8 "UTF-8" - -You will need to override these definitions if they are different on your -system. -.IP CURLOPT_INTERLEAVEFUNCTION -Pass a pointer to a function that matches the following prototype: -\fBsize_t function( void *ptr, size_t size, size_t nmemb, void -*userdata)\fP. This function gets called by libcurl as soon as it has received -interleaved RTP data. This function gets called for each $ block and therefore -contains exactly one upper-layer protocol unit (e.g. one RTP packet). Curl -writes the interleaved header as well as the included data for each call. The -first byte is always an ASCII dollar sign. The dollar sign is followed by a -one byte channel identifier and then a 2 byte integer length in network byte -order. See \fIRFC2326 Section 10.12\fP for more information on how RTP -interleaving behaves. If unset or set to NULL, curl will use the default write -function. - -Interleaved RTP poses some challenges for the client application. Since the -stream data is sharing the RTSP control connection, it is critical to service -the RTP in a timely fashion. If the RTP data is not handled quickly, -subsequent response processing may become unreasonably delayed and the -connection may close. The application may use \fICURL_RTSPREQ_RECEIVE\fP to -service RTP data when no requests are desired. If the application makes a -request, (e.g. \fICURL_RTSPREQ_PAUSE\fP) then the response handler will -process any pending RTP data before marking the request as finished. (Added -in 7.20.0) -.IP CURLOPT_INTERLEAVEDATA -This is the userdata pointer that will be passed to -\fICURLOPT_INTERLEAVEFUNCTION\fP when interleaved RTP data is received. (Added -in 7.20.0) -.IP CURLOPT_CHUNK_BGN_FUNCTION -Pass a pointer to a function that matches the following prototype: -\fBlong function (const void *transfer_info, void *ptr, int remains)\fP. This -function gets called by libcurl before a part of the stream is going to be -transferred (if the transfer supports chunks). - -This callback makes sense only when using the \fICURLOPT_WILDCARDMATCH\fP -option for now. - -The target of transfer_info parameter is a "feature depended" structure. For -the FTP wildcard download, the target is curl_fileinfo structure (see -\fIcurl/curl.h\fP). The parameter ptr is a pointer given by -\fICURLOPT_CHUNK_DATA\fP. The parameter remains contains number of chunks -remaining per the transfer. If the feature is not available, the parameter has -zero value. - -Return \fICURL_CHUNK_BGN_FUNC_OK\fP if everything is fine, -\fICURL_CHUNK_BGN_FUNC_SKIP\fP if you want to skip the concrete chunk or -\fICURL_CHUNK_BGN_FUNC_FAIL\fP to tell libcurl to stop if some error occurred. -(This was added in 7.21.0) -.IP CURLOPT_CHUNK_END_FUNCTION -Pass a pointer to a function that matches the following prototype: -\fBlong function(void *ptr)\fP. This function gets called by libcurl as soon -as a part of the stream has been transferred (or skipped). - -Return \fICURL_CHUNK_END_FUNC_OK\fP if everything is fine or -\fBCURL_CHUNK_END_FUNC_FAIL\fP to tell the lib to stop if some error occurred. -(This was added in 7.21.0) -.IP CURLOPT_CHUNK_DATA -Pass a pointer that will be untouched by libcurl and passed as the ptr -argument to the \fICURL_CHUNK_BGN_FUNTION\fP and \fICURL_CHUNK_END_FUNTION\fP. -(This was added in 7.21.0) -.IP CURLOPT_FNMATCH_FUNCTION -Pass a pointer to a function that matches the following prototype: \fBint -function(void *ptr, const char *pattern, const char *string)\fP prototype (see -\fIcurl/curl.h\fP). It is used internally for the wildcard matching feature. - -Return \fICURL_FNMATCHFUNC_MATCH\fP if pattern matches the string, -\fICURL_FNMATCHFUNC_NOMATCH\fP if not or \fICURL_FNMATCHFUNC_FAIL\fP if an -error occurred. (This was added in 7.21.0) -.IP CURLOPT_FNMATCH_DATA -Pass a pointer that will be untouched by libcurl and passed as the ptr argument -to the \fICURL_FNMATCH_FUNCTION\fP. (This was added in 7.21.0) -.SH ERROR OPTIONS -.IP CURLOPT_ERRORBUFFER -Pass a char * to a buffer that the libcurl may store human readable error -messages in. This may be more helpful than just the return code from -\fIcurl_easy_perform\fP. The buffer must be at least CURL_ERROR_SIZE big. -Although this argument is a 'char *', it does not describe an input string. -Therefore the (probably undefined) contents of the buffer is NOT copied by the -library. You must keep the associated storage available until libcurl no -longer needs it. Failing to do so will cause very odd behavior or even -crashes. libcurl will need it until you call \fIcurl_easy_cleanup(3)\fP or you -set the same option again to use a different pointer. - -Use \fICURLOPT_VERBOSE\fP and \fICURLOPT_DEBUGFUNCTION\fP to better -debug/trace why errors happen. - -If the library does not return an error, the buffer may not have been -touched. Do not rely on the contents in those cases. - -.IP CURLOPT_STDERR -Pass a FILE * as parameter. Tell libcurl to use this stream instead of stderr -when showing the progress meter and displaying \fICURLOPT_VERBOSE\fP data. -.IP CURLOPT_FAILONERROR -A parameter set to 1 tells the library to fail silently if the HTTP code -returned is equal to or larger than 400. The default action would be to return -the page normally, ignoring that code. - -This method is not fail-safe and there are occasions where non-successful -response codes will slip through, especially when authentication is involved -(response codes 401 and 407). - -You might get some amounts of headers transferred before this situation is -detected, like when a "100-continue" is received as a response to a -POST/PUT and a 401 or 407 is received immediately afterwards. -.SH NETWORK OPTIONS -.IP CURLOPT_URL -Pass in a pointer to the actual URL to deal with. The parameter should be a -char * to a zero terminated string which must be URL-encoded in the following -format: - -scheme://host:port/path - -For a greater explanation of the format please see RFC3986. - -If the given URL lacks the scheme, or protocol, part ("http://" or "ftp://" -etc), libcurl will attempt to resolve which protocol to use based on the -given host mame. If the protocol is not supported, libcurl will return -(\fICURLE_UNSUPPORTED_PROTOCOL\fP) when you call \fIcurl_easy_perform(3)\fP -or \fIcurl_multi_perform(3)\fP. Use \fIcurl_version_info(3)\fP for detailed -information on which protocols are supported. - -The host part of the URL contains the address of the server that you want to -connect to. This can be the fully qualified domain name of the server, the -local network name of the machine on your network or the IP address of the -server or machine represented by either an IPv4 or IPv6 address. For example: - -http://www.example.com/ - -http://hostname/ - -http://192.168.0.1/ - -http://[2001:1890:1112:1::20]/ - -It is also possible to specify the user name and password as part of the -host, for some protocols, when connecting to servers that require -authentication. - -For example the following types of authentication support this: - -http://user:password@www.example.com - -ftp://user:password@ftp.example.com - -pop3://user:password@mail.example.com - -The port is optional and when not specified libcurl will use the default port -based on the determined or specified protocol: 80 for HTTP, 21 for FTP and 25 -for SMTP, etc. The following examples show how to specify the port: - -http://www.example.com:8080/ - This will connect to a web server using port -8080 rather than 80. - -smtp://mail.example.com:587/ - This will connect to a SMTP server on the -alternative mail port. - -The path part of the URL is protocol specific and whilst some examples are -given below this list is not conclusive: - -.B HTTP - -The path part of a HTTP request specifies the file to retrieve and from what -directory. If the directory is not specified then the web server's root -directory is used. If the file is omitted then the default document will be -retrieved for either the directory specified or the root directory. The -exact resource returned for each URL is entirely dependent on the server's -configuration. - -http://www.example.com - This gets the main page from the web server. - -http://www.example.com/index.html - This returns the main page by explicitly -requesting it. - -http://www.example.com/contactus/ - This returns the default document from -the contactus directory. - -.B FTP - -The path part of an FTP request specifies the file to retrieve and from what -directory. If the file part is omitted then libcurl downloads the directory -listing for the directory specified. If the directory is omitted then -the directory listing for the root / home directory will be returned. - -ftp://ftp.example.com - This retrieves the directory listing for the root -directory. - -ftp://ftp.example.com/readme.txt - This downloads the file readme.txt from the -root directory. - -ftp://ftp.example.com/libcurl/readme.txt - This downloads readme.txt from the -libcurl directory. - -ftp://user:password@ftp.example.com/readme.txt - This retrieves the readme.txt -file from the user's home directory. When a username and password is -specified, everything that is specified in the path part is relative to the -user's home directory. To retrieve files from the root directory or a -directory underneath the root directory then the absolute path must be -specified by prepending an additional forward slash to the beginning of the -path. - -ftp://user:password@ftp.example.com//readme.txt - This retrieves the readme.txt -from the root directory when logging in as a specified user. - -.B SMTP - -The path part of a SMTP request specifies the host name to present during -communication with the mail server. If the path is omitted then libcurl will -attempt to resolve the local computer's host name. However, this may not -return the fully qualified domain name that is required by some mail servers -and specifying this path allows you to set an alternative name, such as -your machine's fully qualified domain name, which you might have obtained -from an external function such as gethostname or getaddrinfo. - -smtp://mail.example.com - This connects to the mail server at example.com and -sends your local computer's host name in the HELO / EHLO command. - -smtp://mail.example.com/client.example.com - This will send client.example.com in -the HELO / EHLO command to the mail server at example.com. - -.B POP3 - -The path part of a POP3 request specifies the mailbox (message) to retrieve. -If the mailbox is not specified then a list of waiting messages is returned -instead. - -pop3://user:password@mail.example.com - This lists the available messages -pop3://user:password@mail.example.com/1 - This retrieves the first message - -.B SCP - -The path part of a SCP request specifies the file to retrieve and from what -directory. The file part may not be omitted. The file is taken as an absolute -path from the root directory on the server. To specify a path relative to -the user's home directory on the server, prepend ~/ to the path portion. -If the user name is not embedded in the URL, it can be set with the -\fICURLOPT_USERPWD\fP or \fBCURLOPT_USERNAME\fP option. - -scp://user@example.com/etc/issue - This specifies the file /etc/issue - -scp://example.com/~/my-file - This specifies the file my-file in the -user's home directory on the server - -.B SFTP - -The path part of a SFTP request specifies the file to retrieve and from what -directory. If the file part is omitted then libcurl downloads the directory -listing for the directory specified. If the path ends in a / then a directory -listing is returned instead of a file. If the path is omitted entirely then -the directory listing for the root / home directory will be returned. -If the user name is not embedded in the URL, it can be set with the -\fICURLOPT_USERPWD\fP or \fBCURLOPT_USERNAME\fP option. - -sftp://user:password@example.com/etc/issue - This specifies the file -/etc/issue - -sftp://user@example.com/~/my-file - This specifies the file my-file in the -user's home directory - -sftp://ssh.example.com/~/Documents/ - This requests a directory listing -of the Documents directory under the user's home directory - -.B LDAP - -The path part of a LDAP request can be used to specify the: Distinguished -Name, Attributes, Scope, Filter and Extension for a LDAP search. Each field -is separated by a question mark and when that field is not required an empty -string with the question mark separator should be included. - -ldap://ldap.example.com/o=My%20Organisation - This will perform a LDAP search -with the DN as My Organisation. - -ldap://ldap.example.com/o=My%20Organisation?postalAddress - This will perform -the same search but will only return postalAddress attributes. - -ldap://ldap.example.com/?rootDomainNamingContext - This specifies an empty DN -and requests information about the rootDomainNamingContext attribute for an -Active Directory server. - -For more information about the individual components of a LDAP URL please -see RFC4516. - -.B NOTES - -Starting with version 7.20.0, the fragment part of the URI will not be sent as -part of the path, which was previously the case. - -\fICURLOPT_URL\fP is the only option that \fBmust\fP be set before -\fIcurl_easy_perform(3)\fP is called. - -\fICURLOPT_PROTOCOLS\fP can be used to limit what protocols libcurl will use -for this transfer, independent of what libcurl has been compiled to -support. That may be useful if you accept the URL from an external source and -want to limit the accessibility. -.IP CURLOPT_PROTOCOLS -Pass a long that holds a bitmask of CURLPROTO_* defines. If used, this bitmask -limits what protocols libcurl may use in the transfer. This allows you to have -a libcurl built to support a wide range of protocols but still limit specific -transfers to only be allowed to use a subset of them. By default libcurl will -accept all protocols it supports. See also -\fICURLOPT_REDIR_PROTOCOLS\fP. (Added in 7.19.4) -.IP CURLOPT_REDIR_PROTOCOLS -Pass a long that holds a bitmask of CURLPROTO_* defines. If used, this bitmask -limits what protocols libcurl may use in a transfer that it follows to in a -redirect when \fICURLOPT_FOLLOWLOCATION\fP is enabled. This allows you to -limit specific transfers to only be allowed to use a subset of protocols in -redirections. By default libcurl will allow all protocols except for FILE and -SCP. This is a difference compared to pre-7.19.4 versions which -unconditionally would follow to all protocols supported. (Added in 7.19.4) -.IP CURLOPT_PROXY -Set HTTP proxy to use. The parameter should be a char * to a zero terminated -string holding the host name or dotted IP address. To specify port number in -this string, append :[port] to the end of the host name. The proxy string may -be prefixed with [protocol]:// since any such prefix will be ignored. The -proxy's port number may optionally be specified with the separate option. If -not specified, libcurl will default to using port 1080 for proxies. -\fICURLOPT_PROXYPORT\fP. - -When you tell the library to use a HTTP proxy, libcurl will transparently -convert operations to HTTP even if you specify an FTP URL etc. This may have -an impact on what other features of the library you can use, such as -\fICURLOPT_QUOTE\fP and similar FTP specifics that don't work unless you -tunnel through the HTTP proxy. Such tunneling is activated with -\fICURLOPT_HTTPPROXYTUNNEL\fP. - -libcurl respects the environment variables \fBhttp_proxy\fP, \fBftp_proxy\fP, -\fBall_proxy\fP etc, if any of those are set. The \fICURLOPT_PROXY\fP option -does however override any possibly set environment variables. - -Setting the proxy string to "" (an empty string) will explicitly disable the -use of a proxy, even if there is an environment variable set for it. - -Since 7.14.1, the proxy host string given in environment variables can be -specified the exact same way as the proxy can be set with \fICURLOPT_PROXY\fP, -include protocol prefix (http://) and embedded user + password. - -Since 7.21.7, the proxy string may be specified with a protocol:// prefix to -specify alternative proxy protocols. Use socks4://, socks4a://, socks5:// or -socks5h:// (the last one to enable socks5 and asking the proxy to do the -resolving, also known as CURLPROXY_SOCKS5_HOSTNAME type) to request the -specific SOCKS version to be used. No protocol specified, http:// and all -others will be treated as HTTP proxies. -.IP CURLOPT_PROXYPORT -Pass a long with this option to set the proxy port to connect to unless it is -specified in the proxy string \fICURLOPT_PROXY\fP. -.IP CURLOPT_PROXYTYPE -Pass a long with this option to set type of the proxy. Available options for -this are \fICURLPROXY_HTTP\fP, \fICURLPROXY_HTTP_1_0\fP (added in 7.19.4), -\fICURLPROXY_SOCKS4\fP (added in 7.10), \fICURLPROXY_SOCKS5\fP, -\fICURLPROXY_SOCKS4A\fP (added in 7.18.0) and \fICURLPROXY_SOCKS5_HOSTNAME\fP -(added in 7.18.0). The HTTP type is default. (Added in 7.10) - -If you set \fBCURLOPT_PROXYTYPE\fP to \fICURLPROXY_HTTP_1_0\fP, it will only -affect how libcurl speaks to a proxy when CONNECT is used. The HTTP version -used for "regular" HTTP requests is instead controlled with -\fICURLOPT_HTTP_VERSION\fP. -.IP CURLOPT_NOPROXY -Pass a pointer to a zero terminated string. The string consists of a comma -separated list of host names that do not require a proxy to get reached, even -if one is specified. The only wildcard available is a single * character, -which matches all hosts, and effectively disables the proxy. Each name in this -list is matched as either a domain which contains the hostname, or the -hostname itself. For example, example.com would match example.com, -example.com:80, and www.example.com, but not www.notanexample.com. (Added in -7.19.4) -.IP CURLOPT_HTTPPROXYTUNNEL -Set the parameter to 1 to make the library tunnel all operations through a -given HTTP proxy. There is a big difference between using a proxy and to -tunnel through it. If you don't know what this means, you probably don't want -this tunneling option. -.IP CURLOPT_SOCKS5_GSSAPI_SERVICE -Pass a char * as parameter to a string holding the name of the service. The -default service name for a SOCKS5 server is rcmd/server-fqdn. This option -allows you to change it. (Added in 7.19.4) -.IP CURLOPT_SOCKS5_GSSAPI_NEC -Pass a long set to 1 to enable or 0 to disable. As part of the gssapi -negotiation a protection mode is negotiated. The RFC1961 says in section -4.3/4.4 it should be protected, but the NEC reference implementation does not. -If enabled, this option allows the unprotected exchange of the protection mode -negotiation. (Added in 7.19.4). -.IP CURLOPT_INTERFACE -Pass a char * as parameter. This sets the interface name to use as outgoing -network interface. The name can be an interface name, an IP address, or a host -name. - -Starting with 7.24.0: If the parameter starts with "if!" then it is treated as -only as interface name and no attempt will ever be named to do treat it as an -IP address or to do name resolution on it. If the parameter starts with -\&"host!" it is treated as either an IP address or a hostname. Hostnames are -resolved synchronously. Using the if! format is highly recommended when using -the multi interfaces to avoid allowing the code to block. If "if!" is -specified but the parameter does not match an existing interface, -CURLE_INTERFACE_FAILED is returned. -.IP CURLOPT_LOCALPORT -Pass a long. This sets the local port number of the socket used for -connection. This can be used in combination with \fICURLOPT_INTERFACE\fP and -you are recommended to use \fICURLOPT_LOCALPORTRANGE\fP as well when this is -set. Valid port numbers are 1 - 65535. (Added in 7.15.2) -.IP CURLOPT_LOCALPORTRANGE -Pass a long. This is the number of attempts libcurl will make to find a -working local port number. It starts with the given \fICURLOPT_LOCALPORT\fP -and adds one to the number for each retry. Setting this to 1 or below will -make libcurl do only one try for the exact port number. Port numbers by nature -are scarce resources that will be busy at times so setting this value to -something too low might cause unnecessary connection setup failures. (Added in -7.15.2) -.IP CURLOPT_DNS_CACHE_TIMEOUT -Pass a long, this sets the timeout in seconds. Name resolves will be kept in -memory for this number of seconds. Set to zero to completely disable -caching, or set to -1 to make the cached entries remain forever. By default, -libcurl caches this info for 60 seconds. - -The name resolve functions of various libc implementations don't re-read name -server information unless explicitly told so (for example, by calling -\fIres_init(3)\fP). This may cause libcurl to keep using the older server even -if DHCP has updated the server info, and this may look like a DNS cache issue -to the casual libcurl-app user. -.IP CURLOPT_DNS_USE_GLOBAL_CACHE -Pass a long. If the value is 1, it tells curl to use a global DNS cache -that will survive between easy handle creations and deletions. This is not -thread-safe and this will use a global variable. - -\fBWARNING:\fP this option is considered obsolete. Stop using it. Switch over -to using the share interface instead! See \fICURLOPT_SHARE\fP and -\fIcurl_share_init(3)\fP. -.IP CURLOPT_BUFFERSIZE -Pass a long specifying your preferred size (in bytes) for the receive buffer -in libcurl. The main point of this would be that the write callback gets -called more often and with smaller chunks. This is just treated as a request, -not an order. You cannot be guaranteed to actually get the given size. (Added -in 7.10) - -This size is by default set as big as possible (CURL_MAX_WRITE_SIZE), so it -only makes sense to use this option if you want it smaller. -.IP CURLOPT_PORT -Pass a long specifying what remote port number to connect to, instead of the -one specified in the URL or the default port for the used protocol. -.IP CURLOPT_TCP_NODELAY -Pass a long specifying whether the TCP_NODELAY option is to be set or cleared -(1 = set, 0 = clear). The option is cleared by default. This will have no -effect after the connection has been established. - -Setting this option will disable TCP's Nagle algorithm. The purpose of this -algorithm is to try to minimize the number of small packets on the network -(where "small packets" means TCP segments less than the Maximum Segment Size -(MSS) for the network). - -Maximizing the amount of data sent per TCP segment is good because it -amortizes the overhead of the send. However, in some cases (most notably -telnet or rlogin) small segments may need to be sent without delay. This is -less efficient than sending larger amounts of data at a time, and can -contribute to congestion on the network if overdone. -.IP CURLOPT_ADDRESS_SCOPE -Pass a long specifying the scope_id value to use when connecting to IPv6 -link-local or site-local addresses. (Added in 7.19.0) -.IP CURLOPT_TCP_KEEPALIVE -Pass a long. If set to 1, TCP keepalive probes will be sent. The delay and -frequency of these probes can be controlled by the \fICURLOPT_TCP_KEEPIDLE\fP -and \fICURLOPT_TCP_KEEPINTVL\fP options, provided the operating system supports -them. Set to 0 (default behavior) to disable keepalive probes (Added in -7.25.0). -.IP CURLOPT_TCP_KEEPIDLE -Pass a long. Sets the delay, in seconds, that the operating system will wait -while the connection is idle before sending keepalive probes. Not all operating -systems support this option. (Added in 7.25.0) -.IP CURLOPT_TCP_KEEPINTVL -Pass a long. Sets the interval, in seconds, that the operating system will wait -between sending keepalive probes. Not all operating systems support this -option. (Added in 7.25.0) -.SH NAMES and PASSWORDS OPTIONS (Authentication) -.IP CURLOPT_NETRC -This parameter controls the preference of libcurl between using user names and -passwords from your \fI~/.netrc\fP file, relative to user names and passwords -in the URL supplied with \fICURLOPT_URL\fP. - -libcurl uses a user name (and supplied or prompted password) supplied with -\fICURLOPT_USERPWD\fP in preference to any of the options controlled by this -parameter. - -Pass a long, set to one of the values described below. -.RS -.IP CURL_NETRC_OPTIONAL -The use of your \fI~/.netrc\fP file is optional, and information in the URL is -to be preferred. The file will be scanned for the host and user name (to -find the password only) or for the host only, to find the first user name and -password after that \fImachine\fP, which ever information is not specified in -the URL. - -Undefined values of the option will have this effect. -.IP CURL_NETRC_IGNORED -The library will ignore the file and use only the information in the URL. - -This is the default. -.IP CURL_NETRC_REQUIRED -This value tells the library that use of the file is required, to ignore the -information in the URL, and to search the file for the host only. -.RE -Only machine name, user name and password are taken into account -(init macros and similar things aren't supported). - -libcurl does not verify that the file has the correct properties set (as the -standard Unix ftp client does). It should only be readable by user. -.IP CURLOPT_NETRC_FILE -Pass a char * as parameter, pointing to a zero terminated string containing -the full path name to the file you want libcurl to use as .netrc file. If this -option is omitted, and \fICURLOPT_NETRC\fP is set, libcurl will attempt to -find a .netrc file in the current user's home directory. (Added in 7.10.9) -.IP CURLOPT_USERPWD -Pass a char * as parameter, which should be [user name]:[password] to use for -the connection. Use \fICURLOPT_HTTPAUTH\fP to decide the authentication method. - -When using NTLM, you can set the domain by prepending it to the user name and -separating the domain and name with a forward (/) or backward slash (\\). Like -this: "domain/user:password" or "domain\\user:password". Some HTTP servers (on -Windows) support this style even for Basic authentication. - -When using HTTP and \fICURLOPT_FOLLOWLOCATION\fP, libcurl might perform -several requests to possibly different hosts. libcurl will only send this user -and password information to hosts using the initial host name (unless -\fICURLOPT_UNRESTRICTED_AUTH\fP is set), so if libcurl follows locations to -other hosts it will not send the user and password to those. This is enforced -to prevent accidental information leakage. -.IP CURLOPT_PROXYUSERPWD -Pass a char * as parameter, which should be [user name]:[password] to use for -the connection to the HTTP proxy. Use \fICURLOPT_PROXYAUTH\fP to decide -the authentication method. -.IP CURLOPT_USERNAME -Pass a char * as parameter, which should be pointing to the zero terminated -user name to use for the transfer. - -\fBCURLOPT_USERNAME\fP sets the user name to be used in protocol -authentication. You should not use this option together with the (older) -CURLOPT_USERPWD option. - -In order to specify the password to be used in conjunction with the user name -use the \fICURLOPT_PASSWORD\fP option. (Added in 7.19.1) -.IP CURLOPT_PASSWORD -Pass a char * as parameter, which should be pointing to the zero terminated -password to use for the transfer. - -The CURLOPT_PASSWORD option should be used in conjunction with -the \fICURLOPT_USERNAME\fP option. (Added in 7.19.1) -.IP CURLOPT_PROXYUSERNAME -Pass a char * as parameter, which should be pointing to the zero terminated -user name to use for the transfer while connecting to Proxy. - -The CURLOPT_PROXYUSERNAME option should be used in same way as the -\fICURLOPT_PROXYUSERPWD\fP is used. In comparison to -\fICURLOPT_PROXYUSERPWD\fP the CURLOPT_PROXYUSERNAME allows the username to -contain a colon, like in the following example: "sip:user@example.com". The -CURLOPT_PROXYUSERNAME option is an alternative way to set the user name while -connecting to Proxy. There is no meaning to use it together with the -\fICURLOPT_PROXYUSERPWD\fP option. - -In order to specify the password to be used in conjunction with the user name -use the \fICURLOPT_PROXYPASSWORD\fP option. (Added in 7.19.1) -.IP CURLOPT_PROXYPASSWORD -Pass a char * as parameter, which should be pointing to the zero terminated -password to use for the transfer while connecting to Proxy. - -The CURLOPT_PROXYPASSWORD option should be used in conjunction with -the \fICURLOPT_PROXYUSERNAME\fP option. (Added in 7.19.1) -.IP CURLOPT_HTTPAUTH -Pass a long as parameter, which is set to a bitmask, to tell libcurl which -authentication method(s) you want it to use. The available bits are listed -below. If more than one bit is set, libcurl will first query the site to see -which authentication methods it supports and then pick the best one you allow -it to use. For some methods, this will induce an extra network round-trip. Set -the actual name and password with the \fICURLOPT_USERPWD\fP option or -with the \fICURLOPT_USERNAME\fP and the \fICURLOPT_PASSWORD\fP options. -(Added in 7.10.6) -.RS -.IP CURLAUTH_BASIC -HTTP Basic authentication. This is the default choice, and the only method -that is in wide-spread use and supported virtually everywhere. This sends -the user name and password over the network in plain text, easily captured by -others. -.IP CURLAUTH_DIGEST -HTTP Digest authentication. Digest authentication is defined in RFC2617 and -is a more secure way to do authentication over public networks than the -regular old-fashioned Basic method. -.IP CURLAUTH_DIGEST_IE -HTTP Digest authentication with an IE flavor. Digest authentication is -defined in RFC2617 and is a more secure way to do authentication over public -networks than the regular old-fashioned Basic method. The IE flavor is simply -that libcurl will use a special "quirk" that IE is known to have used before -version 7 and that some servers require the client to use. (This define was -added in 7.19.3) -.IP CURLAUTH_GSSNEGOTIATE -HTTP GSS-Negotiate authentication. The GSS-Negotiate (also known as plain -\&"Negotiate") method was designed by Microsoft and is used in their web -applications. It is primarily meant as a support for Kerberos5 authentication -but may also be used along with other authentication methods. For more -information see IETF draft draft-brezak-spnego-http-04.txt. - -You need to build libcurl with a suitable GSS-API library for this to work. -.IP CURLAUTH_NTLM -HTTP NTLM authentication. A proprietary protocol invented and used by -Microsoft. It uses a challenge-response and hash concept similar to Digest, to -prevent the password from being eavesdropped. - -You need to build libcurl with either OpenSSL, GnuTLS or NSS support for this -option to work, or build libcurl on Windows. -.IP CURLAUTH_NTLM_WB -NTLM delegating to winbind helper. Authentication is performed by a separate -binary application that is executed when needed. The name of the application -is specified at compile time but is typically /usr/bin/ntlm_auth -(Added in 7.22.0) - -Note that libcurl will fork when necessary to run the winbind application and -kill it when complete, calling waitpid() to await its exit when done. On POSIX -operating systems, killing the process will cause a SIGCHLD signal to be -raised (regardless of whether \fICURLOPT_NOSIGNAL\fP is set), which must be -handled intelligently by the application. In particular, the application must -not unconditionally call wait() in its SIGCHLD signal handler to avoid being -subject to a race condition. This behavior is subject to change in future -versions of libcurl. -.IP CURLAUTH_ANY -This is a convenience macro that sets all bits and thus makes libcurl pick any -it finds suitable. libcurl will automatically select the one it finds most -secure. -.IP CURLAUTH_ANYSAFE -This is a convenience macro that sets all bits except Basic and thus makes -libcurl pick any it finds suitable. libcurl will automatically select the one -it finds most secure. -.IP CURLAUTH_ONLY -This is a meta symbol. Or this value together with a single specific auth -value to force libcurl to probe for un-restricted auth and if not, only that -single auth algorithm is acceptable. (Added in 7.21.3) -.RE -.IP CURLOPT_TLSAUTH_TYPE -Pass a long as parameter, which is set to a bitmask, to tell libcurl which -authentication method(s) you want it to use for TLS authentication. -.RS -.IP CURLOPT_TLSAUTH_SRP -TLS-SRP authentication. Secure Remote Password authentication for TLS is -defined in RFC5054 and provides mutual authentication if both sides have a -shared secret. To use TLS-SRP, you must also set the -\fICURLOPT_TLSAUTH_USERNAME\fP and \fICURLOPT_TLSAUTH_PASSWORD\fP options. - -You need to build libcurl with GnuTLS or OpenSSL with TLS-SRP support for this -to work. (Added in 7.21.4) -.RE -.IP CURLOPT_TLSAUTH_USERNAME -Pass a char * as parameter, which should point to the zero terminated username -to use for the TLS authentication method specified with the -\fICURLOPT_TLSAUTH_TYPE\fP option. Requires that the -\fICURLOPT_TLS_PASSWORD\fP option also be set. (Added in 7.21.4) -.IP CURLOPT_TLSAUTH_PASSWORD -Pass a char * as parameter, which should point to the zero terminated password -to use for the TLS authentication method specified with the -\fICURLOPT_TLSAUTH_TYPE\fP option. Requires that the -\fICURLOPT_TLS_USERNAME\fP option also be set. (Added in 7.21.4) -.IP CURLOPT_PROXYAUTH -Pass a long as parameter, which is set to a bitmask, to tell libcurl which -authentication method(s) you want it to use for your proxy authentication. If -more than one bit is set, libcurl will first query the site to see what -authentication methods it supports and then pick the best one you allow it to -use. For some methods, this will induce an extra network round-trip. Set the -actual name and password with the \fICURLOPT_PROXYUSERPWD\fP option. The -bitmask can be constructed by or'ing together the bits listed above for the -\fICURLOPT_HTTPAUTH\fP option. As of this writing, only Basic, Digest and NTLM -work. (Added in 7.10.7) -.SH HTTP OPTIONS -.IP CURLOPT_AUTOREFERER -Pass a parameter set to 1 to enable this. When enabled, libcurl will -automatically set the Referer: field in requests where it follows a Location: -redirect. -.IP CURLOPT_ACCEPT_ENCODING -Sets the contents of the Accept-Encoding: header sent in a HTTP request, and -enables decoding of a response when a Content-Encoding: header is received. -Three encodings are supported: \fIidentity\fP, which does nothing, -\fIdeflate\fP which requests the server to compress its response using the -zlib algorithm, and \fIgzip\fP which requests the gzip algorithm. If a -zero-length string is set, then an Accept-Encoding: header containing all -supported encodings is sent. - -This is a request, not an order; the server may or may not do it. This option -must be set (to any non-NULL value) or else any unsolicited encoding done by -the server is ignored. See the special file lib/README.encoding for details. - -(This option was called CURLOPT_ENCODING before 7.21.6) -.IP CURLOPT_TRANSFER_ENCODING -Adds a request for compressed Transfer Encoding in the outgoing HTTP -request. If the server supports this and so desires, it can respond with the -HTTP response sent using a compressed Transfer-Encoding that will be -automatically uncompressed by libcurl on reception. - -Transfer-Encoding differs slightly from the Content-Encoding you ask for with -\fBCURLOPT_ACCEPT_ENCODING\fP in that a Transfer-Encoding is strictly meant to -be for the transfer and thus MUST be decoded before the data arrives in the -client. Traditionally, Transfer-Encoding has been much less used and supported -by both HTTP clients and HTTP servers. - -(Added in 7.21.6) -.IP CURLOPT_FOLLOWLOCATION -A parameter set to 1 tells the library to follow any Location: header that the -server sends as part of a HTTP header. - -This means that the library will re-send the same request on the new location -and follow new Location: headers all the way until no more such headers are -returned. \fICURLOPT_MAXREDIRS\fP can be used to limit the number of redirects -libcurl will follow. - -Since 7.19.4, libcurl can limit what protocols it will automatically -follow. The accepted protocols are set with \fICURLOPT_REDIR_PROTOCOLS\fP and -it excludes the FILE protocol by default. -.IP CURLOPT_UNRESTRICTED_AUTH -A parameter set to 1 tells the library it can continue to send authentication -(user+password) when following locations, even when hostname changed. This -option is meaningful only when setting \fICURLOPT_FOLLOWLOCATION\fP. -.IP CURLOPT_MAXREDIRS -Pass a long. The set number will be the redirection limit. If that many -redirections have been followed, the next redirect will cause an error -(\fICURLE_TOO_MANY_REDIRECTS\fP). This option only makes sense if the -\fICURLOPT_FOLLOWLOCATION\fP is used at the same time. Added in 7.15.1: -Setting the limit to 0 will make libcurl refuse any redirect. Set it to -1 for -an infinite number of redirects (which is the default) -.IP CURLOPT_POSTREDIR -Pass a bitmask to control how libcurl acts on redirects after POSTs that get a -301, 302 or 303 response back. A parameter with bit 0 set (value -\fBCURL_REDIR_POST_301\fP) tells the library to respect RFC2616/10.3.2 and not -convert POST requests into GET requests when following a 301 redirection. -Setting bit 1 (value \fBCURL_REDIR_POST_302\fP) makes libcurl maintain the -request method after a 302 redirect whilst setting bit 2 (value -\fBCURL_REDIR_POST_303\fP) makes libcurl maintain the request method after a -303 redirect. The value \fBCURL_REDIR_POST_ALL\fP is a convenience define that -sets all three bits. - -The non-RFC behaviour is ubiquitous in web browsers, so the library does the -conversion by default to maintain consistency. However, a server may require a -POST to remain a POST after such a redirection. This option is meaningful only -when setting \fICURLOPT_FOLLOWLOCATION\fP. (Added in 7.17.1) (This option was -known as CURLOPT_POST301 up to 7.19.0 as it only supported the 301 then) -.IP CURLOPT_PUT -A parameter set to 1 tells the library to use HTTP PUT to transfer data. The -data should be set with \fICURLOPT_READDATA\fP and \fICURLOPT_INFILESIZE\fP. - -This option is deprecated and starting with version 7.12.1 you should instead -use \fICURLOPT_UPLOAD\fP. -.IP CURLOPT_POST -A parameter set to 1 tells the library to do a regular HTTP post. This will -also make the library use a "Content-Type: -application/x-www-form-urlencoded" header. (This is by far the most commonly -used POST method). - -Use one of \fICURLOPT_POSTFIELDS\fP or \fICURLOPT_COPYPOSTFIELDS\fP options to -specify what data to post and \fICURLOPT_POSTFIELDSIZE\fP or -\fICURLOPT_POSTFIELDSIZE_LARGE\fP to set the data size. - -Optionally, you can provide data to POST using the \fICURLOPT_READFUNCTION\fP -and \fICURLOPT_READDATA\fP options but then you must make sure to not set -\fICURLOPT_POSTFIELDS\fP to anything but NULL. When providing data with a -callback, you must transmit it using chunked transfer-encoding or you must set -the size of the data with the \fICURLOPT_POSTFIELDSIZE\fP or -\fICURLOPT_POSTFIELDSIZE_LARGE\fP option. To enable chunked encoding, you -simply pass in the appropriate Transfer-Encoding header, see the -post-callback.c example. - -You can override the default POST Content-Type: header by setting your own -with \fICURLOPT_HTTPHEADER\fP. - -Using POST with HTTP 1.1 implies the use of a "Expect: 100-continue" header. -You can disable this header with \fICURLOPT_HTTPHEADER\fP as usual. - -If you use POST to a HTTP 1.1 server, you can send data without knowing the -size before starting the POST if you use chunked encoding. You enable this by -adding a header like "Transfer-Encoding: chunked" with -\fICURLOPT_HTTPHEADER\fP. With HTTP 1.0 or without chunked transfer, you must -specify the size in the request. - -When setting \fICURLOPT_POST\fP to 1, it will automatically set -\fICURLOPT_NOBODY\fP to 0 (since 7.14.1). - -If you issue a POST request and then want to make a HEAD or GET using the same -re-used handle, you must explicitly set the new request type using -\fICURLOPT_NOBODY\fP or \fICURLOPT_HTTPGET\fP or similar. -.IP CURLOPT_POSTFIELDS -Pass a void * as parameter, which should be the full data to post in a HTTP -POST operation. You must make sure that the data is formatted the way you want -the server to receive it. libcurl will not convert or encode it for you. Most -web servers will assume this data to be url-encoded. - -The pointed data are NOT copied by the library: as a consequence, they must -be preserved by the calling application until the transfer finishes. - -This POST is a normal application/x-www-form-urlencoded kind (and libcurl will -set that Content-Type by default when this option is used), which is the most -commonly used one by HTML forms. See also the \fICURLOPT_POST\fP. Using -\fICURLOPT_POSTFIELDS\fP implies \fICURLOPT_POST\fP. - -If you want to do a zero-byte POST, you need to set -\fICURLOPT_POSTFIELDSIZE\fP explicitly to zero, as simply setting -\fICURLOPT_POSTFIELDS\fP to NULL or "" just effectively disables the sending -of the specified string. libcurl will instead assume that you'll send the POST -data using the read callback! - -Using POST with HTTP 1.1 implies the use of a "Expect: 100-continue" header. -You can disable this header with \fICURLOPT_HTTPHEADER\fP as usual. - -To make multipart/formdata posts (aka RFC2388-posts), check out the -\fICURLOPT_HTTPPOST\fP option. -.IP CURLOPT_POSTFIELDSIZE -If you want to post data to the server without letting libcurl do a strlen() -to measure the data size, this option must be used. When this option is used -you can post fully binary data, which otherwise is likely to fail. If this -size is set to -1, the library will use strlen() to get the size. -.IP CURLOPT_POSTFIELDSIZE_LARGE -Pass a curl_off_t as parameter. Use this to set the size of the -\fICURLOPT_POSTFIELDS\fP data to prevent libcurl from doing strlen() on the -data to figure out the size. This is the large file version of the -\fICURLOPT_POSTFIELDSIZE\fP option. (Added in 7.11.1) -.IP CURLOPT_COPYPOSTFIELDS -Pass a char * as parameter, which should be the full data to post in a HTTP -POST operation. It behaves as the \fICURLOPT_POSTFIELDS\fP option, but the -original data are copied by the library, allowing the application to overwrite -the original data after setting this option. - -Because data are copied, care must be taken when using this option in -conjunction with \fICURLOPT_POSTFIELDSIZE\fP or -\fICURLOPT_POSTFIELDSIZE_LARGE\fP: If the size has not been set prior to -\fICURLOPT_COPYPOSTFIELDS\fP, the data are assumed to be a NUL-terminated -string; else the stored size informs the library about the data byte count to -copy. In any case, the size must not be changed after -\fICURLOPT_COPYPOSTFIELDS\fP, unless another \fICURLOPT_POSTFIELDS\fP or -\fICURLOPT_COPYPOSTFIELDS\fP option is issued. -(Added in 7.17.1) -.IP CURLOPT_HTTPPOST -Tells libcurl you want a multipart/formdata HTTP POST to be made and you -instruct what data to pass on to the server. Pass a pointer to a linked list -of curl_httppost structs as parameter. The easiest way to create such a -list, is to use \fIcurl_formadd(3)\fP as documented. The data in this list -must remain intact until you close this curl handle again with -\fIcurl_easy_cleanup(3)\fP. - -Using POST with HTTP 1.1 implies the use of a "Expect: 100-continue" header. -You can disable this header with \fICURLOPT_HTTPHEADER\fP as usual. - -When setting \fICURLOPT_HTTPPOST\fP, it will automatically set -\fICURLOPT_NOBODY\fP to 0 (since 7.14.1). -.IP CURLOPT_REFERER -Pass a pointer to a zero terminated string as parameter. It will be used to -set the Referer: header in the http request sent to the remote server. This -can be used to fool servers or scripts. You can also set any custom header -with \fICURLOPT_HTTPHEADER\fP. -.IP CURLOPT_USERAGENT -Pass a pointer to a zero terminated string as parameter. It will be used to -set the User-Agent: header in the http request sent to the remote server. This -can be used to fool servers or scripts. You can also set any custom header -with \fICURLOPT_HTTPHEADER\fP. -.IP CURLOPT_HTTPHEADER -Pass a pointer to a linked list of HTTP headers to pass to the server in your -HTTP request. The linked list should be a fully valid list of \fBstruct -curl_slist\fP structs properly filled in. Use \fIcurl_slist_append(3)\fP to -create the list and \fIcurl_slist_free_all(3)\fP to clean up an entire -list. If you add a header that is otherwise generated and used by libcurl -internally, your added one will be used instead. If you add a header with no -content as in 'Accept:' (no data on the right side of the colon), the -internally used header will get disabled. Thus, using this option you can add -new headers, replace internal headers and remove internal headers. To add a -header with no content, make the content be two quotes: \&"". The headers -included in the linked list must not be CRLF-terminated, because curl adds -CRLF after each header item. Failure to comply with this will result in -strange bugs because the server will most likely ignore part of the headers -you specified. - -The first line in a request (containing the method, usually a GET or POST) is -not a header and cannot be replaced using this option. Only the lines -following the request-line are headers. Adding this method line in this list -of headers will only cause your request to send an invalid header. - -Pass a NULL to this to reset back to no custom headers. - -The most commonly replaced headers have "shortcuts" in the options -\fICURLOPT_COOKIE\fP, \fICURLOPT_USERAGENT\fP and \fICURLOPT_REFERER\fP. -.IP CURLOPT_HTTP200ALIASES -Pass a pointer to a linked list of aliases to be treated as valid HTTP 200 -responses. Some servers respond with a custom header response line. For -example, IceCast servers respond with "ICY 200 OK". By including this string -in your list of aliases, the response will be treated as a valid HTTP header -line such as "HTTP/1.0 200 OK". (Added in 7.10.3) - -The linked list should be a fully valid list of struct curl_slist structs, and -be properly filled in. Use \fIcurl_slist_append(3)\fP to create the list and -\fIcurl_slist_free_all(3)\fP to clean up an entire list. - -The alias itself is not parsed for any version strings. Before libcurl 7.16.3, -Libcurl used the value set by option \fICURLOPT_HTTP_VERSION\fP, but starting -with 7.16.3 the protocol is assumed to match HTTP 1.0 when an alias matched. -.IP CURLOPT_COOKIE -Pass a pointer to a zero terminated string as parameter. It will be used to -set a cookie in the http request. The format of the string should be -NAME=CONTENTS, where NAME is the cookie name and CONTENTS is what the cookie -should contain. - -If you need to set multiple cookies, you need to set them all using a single -option and thus you need to concatenate them all in one single string. Set -multiple cookies in one string like this: "name1=content1; name2=content2;" -etc. - -This option sets the cookie header explicitly in the outgoing request(s). If -multiple requests are done due to authentication, followed redirections or -similar, they will all get this cookie passed on. - -Using this option multiple times will only make the latest string override the -previous ones. -.IP CURLOPT_COOKIEFILE -Pass a pointer to a zero terminated string as parameter. It should contain the -name of your file holding cookie data to read. The cookie data may be in -Netscape / Mozilla cookie data format or just regular HTTP-style headers -dumped to a file. - -Given an empty or non-existing file or by passing the empty string (""), this -option will enable cookies for this curl handle, making it understand and -parse received cookies and then use matching cookies in future requests. - -If you use this option multiple times, you just add more files to read. -Subsequent files will add more cookies. -.IP CURLOPT_COOKIEJAR -Pass a file name as char *, zero terminated. This will make libcurl write all -internally known cookies to the specified file when \fIcurl_easy_cleanup(3)\fP -is called. If no cookies are known, no file will be created. Specify "-" to -instead have the cookies written to stdout. Using this option also enables -cookies for this session, so if you for example follow a location it will make -matching cookies get sent accordingly. - -If the cookie jar file can't be created or written to (when the -\fIcurl_easy_cleanup(3)\fP is called), libcurl will not and cannot report an -error for this. Using \fICURLOPT_VERBOSE\fP or \fICURLOPT_DEBUGFUNCTION\fP -will get a warning to display, but that is the only visible feedback you get -about this possibly lethal situation. -.IP CURLOPT_COOKIESESSION -Pass a long set to 1 to mark this as a new cookie "session". It will force -libcurl to ignore all cookies it is about to load that are "session cookies" -from the previous session. By default, libcurl always stores and loads all -cookies, independent if they are session cookies or not. Session cookies are -cookies without expiry date and they are meant to be alive and existing for -this "session" only. -.IP CURLOPT_COOKIELIST -Pass a char * to a cookie string. Cookie can be either in Netscape / Mozilla -format or just regular HTTP-style header (Set-Cookie: ...) format. If cURL -cookie engine was not enabled it will enable its cookie engine. Passing a -magic string \&"ALL" will erase all cookies known by cURL. (Added in 7.14.1) -Passing the special string \&"SESS" will only erase all session cookies known -by cURL. (Added in 7.15.4) Passing the special string \&"FLUSH" will write -all cookies known by cURL to the file specified by \fICURLOPT_COOKIEJAR\fP. -(Added in 7.17.1) -.IP CURLOPT_HTTPGET -Pass a long. If the long is 1, this forces the HTTP request to get back -to GET. Usable if a POST, HEAD, PUT, or a custom request has been used -previously using the same curl handle. - -When setting \fICURLOPT_HTTPGET\fP to 1, it will automatically set -\fICURLOPT_NOBODY\fP to 0 (since 7.14.1). -.IP CURLOPT_HTTP_VERSION -Pass a long, set to one of the values described below. They force libcurl to -use the specific HTTP versions. This is not sensible to do unless you have a -good reason. -.RS -.IP CURL_HTTP_VERSION_NONE -We don't care about what version the library uses. libcurl will use whatever -it thinks fit. -.IP CURL_HTTP_VERSION_1_0 -Enforce HTTP 1.0 requests. -.IP CURL_HTTP_VERSION_1_1 -Enforce HTTP 1.1 requests. -.RE -.IP CURLOPT_IGNORE_CONTENT_LENGTH -Ignore the Content-Length header. This is useful for Apache 1.x (and similar -servers) which will report incorrect content length for files over 2 -gigabytes. If this option is used, curl will not be able to accurately report -progress, and will simply stop the download when the server ends the -connection. (added in 7.14.1) -.IP CURLOPT_HTTP_CONTENT_DECODING -Pass a long to tell libcurl how to act on content decoding. If set to zero, -content decoding will be disabled. If set to 1 it is enabled. Libcurl has no -default content decoding but requires you to use \fICURLOPT_ENCODING\fP for -that. (added in 7.16.2) -.IP CURLOPT_HTTP_TRANSFER_DECODING -Pass a long to tell libcurl how to act on transfer decoding. If set to zero, -transfer decoding will be disabled, if set to 1 it is enabled -(default). libcurl does chunked transfer decoding by default unless this -option is set to zero. (added in 7.16.2) -.SH SMTP OPTIONS -.IP CURLOPT_MAIL_FROM -Pass a pointer to a zero terminated string as parameter. This should be used -to specify the sender's email address when sending SMTP mail with libcurl. - -An originator email address should be specified with angled brackets (<>) -around it, which if not specified, will be added by libcurl from version -7.21.4 onwards. Failing to provide such brackets may cause the server to -reject the email. - -If this parameter is not specified then an empty address will be sent to the -mail server which may or may not cause the email to be rejected. - -(Added in 7.20.0) -.IP CURLOPT_MAIL_RCPT -Pass a pointer to a linked list of recipients to pass to the server in your -SMTP mail request. The linked list should be a fully valid list of \fBstruct -curl_slist\fP structs properly filled in. Use \fIcurl_slist_append(3)\fP to -create the list and \fIcurl_slist_free_all(3)\fP to clean up an entire list. - -Each recipient should be specified within a pair of angled brackets (<>), -however, should you not use an angled bracket as the first character libcurl -will assume you provided a single email address and enclose that address -within brackets for you. - -(Added in 7.20.0) -.IP CURLOPT_MAIL_AUTH -Pass a pointer to a zero terminated string as parameter. This will be used -to specify the authentication address (identity) of a submitted message that -is being relayed to another server. - -This optional parameter allows co-operating agents in a trusted environment to -communicate the authentication of individual messages and should only be used -by the application program, using libcurl, if the application is itself a -mail server acting in such an environment. If the application is operating as -such and the AUTH address is not known or is invalid, then an empty string -should be used for this parameter. - -Unlike CURLOPT_MAIL_FROM and CURLOPT_MAIL_RCPT, the address should not be -specified within a pair of angled brackets (<>). However, if an empty string -is used then a pair of brackets will be sent by libcurl as required by -RFC2554. - -(Added in 7.25.0) -.SH TFTP OPTIONS -.IP CURLOPT_TFTP_BLKSIZE -Specify block size to use for TFTP data transmission. Valid range as per -RFC2348 is 8-65464 bytes. The default of 512 bytes will be used if this option -is not specified. The specified block size will only be used pending support -by the remote server. If the server does not return an option acknowledgement -or returns an option acknowledgement with no blksize, the default of 512 bytes -will be used. (added in 7.19.4) -.SH FTP OPTIONS -.IP CURLOPT_FTPPORT -Pass a pointer to a zero terminated string as parameter. It will be used to -get the IP address to use for the FTP PORT instruction. The PORT instruction -tells the remote server to connect to our specified IP address. The string may -be a plain IP address, a host name, a network interface name (under Unix) or -just a '-' symbol to let the library use your system's default IP -address. Default FTP operations are passive, and thus won't use PORT. - -The address can be followed by a ':' to specify a port, optionally followed by -a '-' to specify a port range. If the port specified is 0, the operating -system will pick a free port. If a range is provided and all ports in the -range are not available, libcurl will report CURLE_FTP_PORT_FAILED for the -handle. Invalid port/range settings are ignored. IPv6 addresses followed by -a port or portrange have to be in brackets. IPv6 addresses without port/range -specifier can be in brackets. (added in 7.19.5) - -Examples with specified ports: - -.nf - eth0:0 - 192.168.1.2:32000-33000 - curl.se:32123 - [::1]:1234-4567 -.fi - -You disable PORT again and go back to using the passive version by setting -this option to NULL. -.IP CURLOPT_QUOTE -Pass a pointer to a linked list of FTP or SFTP commands to pass to the server -prior to your FTP request. This will be done before any other commands are -issued (even before the CWD command for FTP). The linked list should be a -fully valid list of 'struct curl_slist' structs properly filled in with text -strings. Use \fIcurl_slist_append(3)\fP to append strings (commands) to the -list, and clear the entire list afterwards with -\fIcurl_slist_free_all(3)\fP. Disable this operation again by setting a NULL -to this option. When speaking to a FTP (or SFTP since 7.24.0) server, prefix -the command with an asterisk (*) to make libcurl continue even if the command -fails as by default libcurl will stop at first failure. - -The set of valid FTP commands depends on the server (see RFC959 for a list of -mandatory commands). - -The valid SFTP commands are: chgrp, chmod, chown, ln, mkdir, pwd, rename, rm, -rmdir, symlink (see -.BR curl (1)) -(SFTP support added in 7.16.3) -.IP CURLOPT_POSTQUOTE -Pass a pointer to a linked list of FTP or SFTP commands to pass to the server -after your FTP transfer request. The commands will only be run if no error -occurred. The linked list should be a fully valid list of struct curl_slist -structs properly filled in as described for \fICURLOPT_QUOTE\fP. Disable this -operation again by setting a NULL to this option. -.IP CURLOPT_PREQUOTE -Pass a pointer to a linked list of FTP commands to pass to the server after -the transfer type is set. The linked list should be a fully valid list of -struct curl_slist structs properly filled in as described for -\fICURLOPT_QUOTE\fP. Disable this operation again by setting a NULL to this -option. Before version 7.16.0, if you also set \fICURLOPT_NOBODY\fP to 1, this -option didn't work. -.IP CURLOPT_DIRLISTONLY -A parameter set to 1 tells the library to just list the names of files in a -directory, instead of doing a full directory listing that would include file -sizes, dates etc. This works for FTP and SFTP URLs. - -This causes an FTP NLST command to be sent on an FTP server. Beware that some -FTP servers list only files in their response to NLST; they might not include -subdirectories and symbolic links. - -Setting this option to 1 also implies a directory listing even if the URL -doesn't end with a slash, which otherwise is necessary. - -Do NOT use this option if you also use \fICURLOPT_WILDCARDMATCH\fP as it will -effectively break that feature then. - -(This option was known as CURLOPT_FTPLISTONLY up to 7.16.4) -.IP CURLOPT_APPEND -A parameter set to 1 tells the library to append to the remote file instead of -overwrite it. This is only useful when uploading to an FTP site. - -(This option was known as CURLOPT_FTPAPPEND up to 7.16.4) -.IP CURLOPT_FTP_USE_EPRT -Pass a long. If the value is 1, it tells curl to use the EPRT (and -LPRT) command when doing active FTP downloads (which is enabled by -\fICURLOPT_FTPPORT\fP). Using EPRT means that it will first attempt to use -EPRT and then LPRT before using PORT, but if you pass zero to this -option, it will not try using EPRT or LPRT, only plain PORT. (Added in 7.10.5) - -If the server is an IPv6 host, this option will have no effect as of 7.12.3. -.IP CURLOPT_FTP_USE_EPSV -Pass a long. If the value is 1, it tells curl to use the EPSV command -when doing passive FTP downloads (which it always does by default). Using EPSV -means that it will first attempt to use EPSV before using PASV, but if you -pass zero to this option, it will not try using EPSV, only plain PASV. - -If the server is an IPv6 host, this option will have no effect as of 7.12.3. -.IP CURLOPT_FTP_USE_PRET -Pass a long. If the value is 1, it tells curl to send a PRET command before -PASV (and EPSV). Certain FTP servers, mainly drftpd, require this non-standard -command for directory listings as well as up and downloads in PASV mode. Has -no effect when using the active FTP transfers mode. (Added in 7.20.0) -.IP CURLOPT_FTP_CREATE_MISSING_DIRS -Pass a long. If the value is 1, curl will attempt to create any remote -directory that it fails to CWD into. CWD is the command that changes working -directory. (Added in 7.10.7) - -This setting also applies to SFTP-connections. curl will attempt to create -the remote directory if it can't obtain a handle to the target-location. The -creation will fail if a file of the same name as the directory to create -already exists or lack of permissions prevents creation. (Added in 7.16.3) - -Starting with 7.19.4, you can also set this value to 2, which will make -libcurl retry the CWD command again if the subsequent MKD command fails. This -is especially useful if you're doing many simultaneous connections against the -same server and they all have this option enabled, as then CWD may first fail -but then another connection does MKD before this connection and thus MKD fails -but trying CWD works! 7.19.4 also introduced the \fICURLFTP_CREATE_DIR\fP and -\fICURLFTP_CREATE_DIR_RETRY\fP enum names for these arguments. - -Before version 7.19.4, libcurl will simply ignore arguments set to 2 and act -as if 1 was selected. -.IP CURLOPT_FTP_RESPONSE_TIMEOUT -Pass a long. Causes curl to set a timeout period (in seconds) on the amount -of time that the server is allowed to take in order to generate a response -message for a command before the session is considered hung. While curl is -waiting for a response, this value overrides \fICURLOPT_TIMEOUT\fP. It is -recommended that if used in conjunction with \fICURLOPT_TIMEOUT\fP, you set -\fICURLOPT_FTP_RESPONSE_TIMEOUT\fP to a value smaller than -\fICURLOPT_TIMEOUT\fP. (Added in 7.10.8) -.IP CURLOPT_FTP_ALTERNATIVE_TO_USER -Pass a char * as parameter, pointing to a string which will be used to -authenticate if the usual FTP "USER user" and "PASS password" negotiation -fails. This is currently only known to be required when connecting to -Tumbleweed's Secure Transport FTPS server using client certificates for -authentication. (Added in 7.15.5) -.IP CURLOPT_FTP_SKIP_PASV_IP -Pass a long. If set to 1, it instructs libcurl to not use the IP address the -server suggests in its 227-response to libcurl's PASV command when libcurl -connects the data connection. Instead libcurl will re-use the same IP address -it already uses for the control connection. But it will use the port number -from the 227-response. (Added in 7.14.2) - -This option has no effect if PORT, EPRT or EPSV is used instead of PASV. -.IP CURLOPT_FTPSSLAUTH -Pass a long using one of the values from below, to alter how libcurl issues -\&"AUTH TLS" or "AUTH SSL" when FTP over SSL is activated (see -\fICURLOPT_USE_SSL\fP). (Added in 7.12.2) -.RS -.IP CURLFTPAUTH_DEFAULT -Allow libcurl to decide. -.IP CURLFTPAUTH_SSL -Try "AUTH SSL" first, and only if that fails try "AUTH TLS". -.IP CURLFTPAUTH_TLS -Try "AUTH TLS" first, and only if that fails try "AUTH SSL". -.RE -.IP CURLOPT_FTP_SSL_CCC -If enabled, this option makes libcurl use CCC (Clear Command Channel). It -shuts down the SSL/TLS layer after authenticating. The rest of the -control channel communication will be unencrypted. This allows NAT routers -to follow the FTP transaction. Pass a long using one of the values below. -(Added in 7.16.1) -.RS -.IP CURLFTPSSL_CCC_NONE -Don't attempt to use CCC. -.IP CURLFTPSSL_CCC_PASSIVE -Do not initiate the shutdown, but wait for the server to do it. Do not send -a reply. -.IP CURLFTPSSL_CCC_ACTIVE -Initiate the shutdown and wait for a reply. -.RE -.IP CURLOPT_FTP_ACCOUNT -Pass a pointer to a zero terminated string (or NULL to disable). When an FTP -server asks for "account data" after user name and password has been provided, -this data is sent off using the ACCT command. (Added in 7.13.0) -.IP CURLOPT_FTP_FILEMETHOD -Pass a long that should have one of the following values. This option controls -what method libcurl should use to reach a file on a FTP(S) server. The -argument should be one of the following alternatives: -.RS -.IP CURLFTPMETHOD_MULTICWD -libcurl does a single CWD operation for each path part in the given URL. For -deep hierarchies this means many commands. This is how RFC1738 says it -should be done. This is the default but the slowest behavior. -.IP CURLFTPMETHOD_NOCWD -libcurl does no CWD at all. libcurl will do SIZE, RETR, STOR etc and give a -full path to the server for all these commands. This is the fastest behavior. -.IP CURLFTPMETHOD_SINGLECWD -libcurl does one CWD with the full target directory and then operates on the -file \&"normally" (like in the multicwd case). This is somewhat more standards -compliant than 'nocwd' but without the full penalty of 'multicwd'. -.RE -(Added in 7.15.1) -.SH RTSP OPTIONS -.IP CURLOPT_RTSP_REQUEST -Tell libcurl what kind of RTSP request to make. Pass one of the following RTSP -enum values. Unless noted otherwise, commands require the Session ID to be -initialized. (Added in 7.20.0) -.RS -.IP CURL_RTSPREQ_OPTIONS -Used to retrieve the available methods of the server. The application is -responsible for parsing and obeying the response. \fB(The session ID is not -needed for this method.)\fP (Added in 7.20.0) -.IP CURL_RTSPREQ_DESCRIBE -Used to get the low level description of a stream. The application should note -what formats it understands in the \fI'Accept:'\fP header. Unless set -manually, libcurl will automatically fill in \fI'Accept: -application/sdp'\fP. Time-condition headers will be added to Describe requests -if the \fICURLOPT_TIMECONDITION\fP option is active. \fB(The session ID is not -needed for this method)\fP (Added in 7.20.0) -.IP CURL_RTSPREQ_ANNOUNCE -When sent by a client, this method changes the description of the session. For -example, if a client is using the server to record a meeting, the client can -use Announce to inform the server of all the meta-information about the -session. ANNOUNCE acts like a HTTP PUT or POST just like -\fICURL_RTSPREQ_SET_PARAMETER\fP (Added in 7.20.0) -.IP CURL_RTSPREQ_SETUP -Setup is used to initialize the transport layer for the session. The -application must set the desired Transport options for a session by using the -\fICURLOPT_RTSP_TRANSPORT\fP option prior to calling setup. If no session ID -is currently set with \fICURLOPT_RTSP_SESSION_ID\fP, libcurl will extract and -use the session ID in the response to this request. \fB(The session ID is not -needed for this method).\fP (Added in 7.20.0) -.IP CURL_RTSPREQ_PLAY -Send a Play command to the server. Use the \fICURLOPT_RANGE\fP option to -modify the playback time (e.g. 'npt=10-15'). (Added in 7.20.0) -.IP CURL_RTSPREQ_PAUSE -Send a Pause command to the server. Use the \fICURLOPT_RANGE\fP option with a -single value to indicate when the stream should be halted. (e.g. npt='25') -(Added in 7.20.0) -.IP CURL_RTSPREQ_TEARDOWN -This command terminates an RTSP session. Simply closing a connection does not -terminate the RTSP session since it is valid to control an RTSP session over -different connections. (Added in 7.20.0) -.IP CURL_RTSPREQ_GET_PARAMETER -Retrieve a parameter from the server. By default, libcurl will automatically -include a \fIContent-Type: text/parameters\fP header on all non-empty requests -unless a custom one is set. GET_PARAMETER acts just like a HTTP PUT or POST -(see \fICURL_RTSPREQ_SET_PARAMETER\fP). -Applications wishing to send a heartbeat message (e.g. in the presence of a -server-specified timeout) should send use an empty GET_PARAMETER request. -(Added in 7.20.0) -.IP CURL_RTSPREQ_SET_PARAMETER -Set a parameter on the server. By default, libcurl will automatically include -a \fIContent-Type: text/parameters\fP header unless a custom one is set. The -interaction with SET_PARAMTER is much like a HTTP PUT or POST. An application -may either use \fICURLOPT_UPLOAD\fP with \fICURLOPT_READDATA\fP like a HTTP -PUT, or it may use \fICURLOPT_POSTFIELDS\fP like a HTTP POST. No chunked -transfers are allowed, so the application must set the -\fICURLOPT_INFILESIZE\fP in the former and \fICURLOPT_POSTFIELDSIZE\fP in the -latter. Also, there is no use of multi-part POSTs within RTSP. (Added in -7.20.0) -.IP CURL_RTSPREQ_RECORD -Used to tell the server to record a session. Use the \fICURLOPT_RANGE\fP -option to modify the record time. (Added in 7.20.0) -.IP CURL_RTSPREQ_RECEIVE -This is a special request because it does not send any data to the server. The -application may call this function in order to receive interleaved RTP -data. It will return after processing one read buffer of data in order to give -the application a chance to run. (Added in 7.20.0) -.RE -.IP CURLOPT_RTSP_SESSION_ID -Pass a char * as a parameter to set the value of the current RTSP Session ID -for the handle. Useful for resuming an in-progress session. Once this value is -set to any non-NULL value, libcurl will return \fICURLE_RTSP_SESSION_ERROR\fP -if ID received from the server does not match. If unset (or set to NULL), -libcurl will automatically set the ID the first time the server sets it in a -response. (Added in 7.20.0) -.IP CURLOPT_RTSP_STREAM_URI -Set the stream URI to operate on by passing a char * . For example, a single -session may be controlling \fIrtsp://foo/twister/audio\fP and -\fIrtsp://foo/twister/video\fP and the application can switch to the -appropriate stream using this option. If unset, libcurl will default to -operating on generic server options by passing '*' in the place of the RTSP -Stream URI. This option is distinct from \fICURLOPT_URL\fP. When working with -RTSP, the \fICURLOPT_STREAM_URI\fP indicates what URL to send to the server in -the request header while the \fICURLOPT_URL\fP indicates where to make the -connection to. (e.g. the \fICURLOPT_URL\fP for the above examples might be -set to \fIrtsp://foo/twister\fP (Added in 7.20.0) -.IP CURLOPT_RTSP_TRANSPORT -Pass a char * to tell libcurl what to pass for the Transport: header for this -RTSP session. This is mainly a convenience method to avoid needing to set a -custom Transport: header for every SETUP request. The application must set a -Transport: header before issuing a SETUP request. (Added in 7.20.0) -.IP CURLOPT_RTSP_HEADER -This option is simply an alias for \fICURLOPT_HTTP_HEADER\fP. Use this to -replace the standard headers that RTSP and HTTP share. It is also valid to use -the shortcuts such as \fICURLOPT_USERAGENT\fP. (Added in 7.20.0) -.IP CURLOPT_RTSP_CLIENT_CSEQ -Manually set the the CSEQ number to issue for the next RTSP request. Useful if -the application is resuming a previously broken connection. The CSEQ will -increment from this new number henceforth. (Added in 7.20.0) -.IP CURLOPT_RTSP_SERVER_CSEQ -Manually set the CSEQ number to expect for the next RTSP Server->Client -request. At the moment, this feature (listening for Server requests) is -unimplemented. (Added in 7.20.0) -.SH PROTOCOL OPTIONS -.IP CURLOPT_TRANSFERTEXT -A parameter set to 1 tells the library to use ASCII mode for FTP transfers, -instead of the default binary transfer. For win32 systems it does not set the -stdout to binary mode. This option can be usable when transferring text data -between systems with different views on certain characters, such as newlines -or similar. - -libcurl does not do a complete ASCII conversion when doing ASCII transfers -over FTP. This is a known limitation/flaw that nobody has rectified. libcurl -simply sets the mode to ASCII and performs a standard transfer. -.IP CURLOPT_PROXY_TRANSFER_MODE -Pass a long. If the value is set to 1 (one), it tells libcurl to set the -transfer mode (binary or ASCII) for FTP transfers done via a HTTP proxy, by -appending ;type=a or ;type=i to the URL. Without this setting, or it being set -to 0 (zero, the default), \fICURLOPT_TRANSFERTEXT\fP has no effect when doing -FTP via a proxy. Beware that not all proxies support this feature. (Added in -7.18.0) -.IP CURLOPT_CRLF -Pass a long. If the value is set to 1 (one), libcurl converts Unix newlines to -CRLF newlines on transfers. Disable this option again by setting the value to -0 (zero). -.IP CURLOPT_RANGE -Pass a char * as parameter, which should contain the specified range you -want. It should be in the format "X-Y", where X or Y may be left out. HTTP -transfers also support several intervals, separated with commas as in -\fI"X-Y,N-M"\fP. Using this kind of multiple intervals will cause the HTTP -server to send the response document in pieces (using standard MIME separation -techniques). For RTSP, the formatting of a range should follow RFC2326 -Section 12.29. For RTSP, byte ranges are \fBnot\fP permitted. Instead, ranges -should be given in npt, utc, or smpte formats. - -Pass a NULL to this option to disable the use of ranges. - -Ranges work on HTTP, FTP, FILE (since 7.18.0), and RTSP (since 7.20.0) -transfers only. -.IP CURLOPT_RESUME_FROM -Pass a long as parameter. It contains the offset in number of bytes that you -want the transfer to start from. Set this option to 0 to make the transfer -start from the beginning (effectively disabling resume). For FTP, set this -option to -1 to make the transfer start from the end of the target file -(useful to continue an interrupted upload). - -When doing uploads with FTP, the resume position is where in the local/source -file libcurl should try to resume the upload from and it will then append the -source file to the remote target file. -.IP CURLOPT_RESUME_FROM_LARGE -Pass a curl_off_t as parameter. It contains the offset in number of bytes that -you want the transfer to start from. (Added in 7.11.0) -.IP CURLOPT_CUSTOMREQUEST -Pass a pointer to a zero terminated string as parameter. It can be used to -specify the request instead of GET or HEAD when performing HTTP based -requests, instead of LIST and NLST when performing FTP directory listings and -instead of LIST and RETR when issuing POP3 based commands. This is -particularly useful, for example, for performing a HTTP DELETE request or a -POP3 DELE command. - -Please don't perform this at will, on HTTP based requests, by making sure -your server supports the command you are sending first. - -When you change the request method by setting \fBCURLOPT_CUSTOMREQUEST\fP to -something, you don't actually change how libcurl behaves or acts in regards -to the particular request method, it will only change the actual string sent -in the request. - -For example: - -With the HTTP protocol when you tell libcurl to do a HEAD request, but then -specify a GET though a custom request libcurl will still act as if it sent a -HEAD. To switch to a proper HEAD use \fICURLOPT_NOBODY\fP, to switch to a -proper POST use \fICURLOPT_POST\fP or \fICURLOPT_POSTFIELDS\fP and to switch -to a proper GET use CURLOPT_HTTPGET. - -With the POP3 protocol when you tell libcurl to use a custom request it will -behave like a LIST or RETR command was sent where it expects data to be -returned by the server. As such \fICURLOPT_NOBODY\fP should be used when -specifying commands such as DELE and NOOP for example. - -Restore to the internal default by setting this to NULL. - -Many people have wrongly used this option to replace the entire request with -their own, including multiple headers and POST contents. While that might -work in many cases, it will cause libcurl to send invalid requests and it -could possibly confuse the remote server badly. Use \fICURLOPT_POST\fP and -\fICURLOPT_POSTFIELDS\fP to set POST data. Use \fICURLOPT_HTTPHEADER\fP to -replace or extend the set of headers sent by libcurl. Use -\fICURLOPT_HTTP_VERSION\fP to change HTTP version. - -(Support for POP3 added in 7.26.0) -.IP CURLOPT_FILETIME -Pass a long. If it is 1, libcurl will attempt to get the modification date of -the remote document in this operation. This requires that the remote server -sends the time or replies to a time querying command. The -\fIcurl_easy_getinfo(3)\fP function with the \fICURLINFO_FILETIME\fP argument -can be used after a transfer to extract the received time (if any). -.IP CURLOPT_NOBODY -A parameter set to 1 tells the library to not include the body-part in the -output. This is only relevant for protocols that have separate header and -body parts. On HTTP(S) servers, this will make libcurl do a HEAD request. - -To change request to GET, you should use \fICURLOPT_HTTPGET\fP. Change -request to POST with \fICURLOPT_POST\fP etc. -.IP CURLOPT_INFILESIZE -When uploading a file to a remote site, this option should be used to tell -libcurl what the expected size of the infile is. This value should be passed -as a long. See also \fICURLOPT_INFILESIZE_LARGE\fP. - -For uploading using SCP, this option or \fICURLOPT_INFILESIZE_LARGE\fP is -mandatory. - -When sending emails using SMTP, this command can be used to specify the -optional SIZE parameter for the MAIL FROM command. (Added in 7.23.0) - -This option does not limit how much data libcurl will actually send, as that -is controlled entirely by what the read callback returns. -.IP CURLOPT_INFILESIZE_LARGE -When uploading a file to a remote site, this option should be used to tell -libcurl what the expected size of the infile is. This value should be passed -as a curl_off_t. (Added in 7.11.0) - -For uploading using SCP, this option or \fICURLOPT_INFILESIZE\fP is mandatory. - -This option does not limit how much data libcurl will actually send, as that -is controlled entirely by what the read callback returns. -.IP CURLOPT_UPLOAD -A parameter set to 1 tells the library to prepare for an upload. The -\fICURLOPT_READDATA\fP and \fICURLOPT_INFILESIZE\fP or -\fICURLOPT_INFILESIZE_LARGE\fP options are also interesting for uploads. If -the protocol is HTTP, uploading means using the PUT request unless you tell -libcurl otherwise. - -Using PUT with HTTP 1.1 implies the use of a "Expect: 100-continue" header. -You can disable this header with \fICURLOPT_HTTPHEADER\fP as usual. - -If you use PUT to a HTTP 1.1 server, you can upload data without knowing the -size before starting the transfer if you use chunked encoding. You enable this -by adding a header like "Transfer-Encoding: chunked" with -\fICURLOPT_HTTPHEADER\fP. With HTTP 1.0 or without chunked transfer, you must -specify the size. -.IP CURLOPT_MAXFILESIZE -Pass a long as parameter. This allows you to specify the maximum size (in -bytes) of a file to download. If the file requested is larger than this value, -the transfer will not start and CURLE_FILESIZE_EXCEEDED will be returned. - -The file size is not always known prior to download, and for such files this -option has no effect even if the file transfer ends up being larger than this -given limit. This concerns both FTP and HTTP transfers. -.IP CURLOPT_MAXFILESIZE_LARGE -Pass a curl_off_t as parameter. This allows you to specify the maximum size -(in bytes) of a file to download. If the file requested is larger than this -value, the transfer will not start and \fICURLE_FILESIZE_EXCEEDED\fP will be -returned. (Added in 7.11.0) - -The file size is not always known prior to download, and for such files this -option has no effect even if the file transfer ends up being larger than this -given limit. This concerns both FTP and HTTP transfers. -.IP CURLOPT_TIMECONDITION -Pass a long as parameter. This defines how the \fICURLOPT_TIMEVALUE\fP time -value is treated. You can set this parameter to \fICURL_TIMECOND_IFMODSINCE\fP -or \fICURL_TIMECOND_IFUNMODSINCE\fP. This feature applies to HTTP, FTP, RTSP, -and FILE. - -The last modification time of a file is not always known and in such instances -this feature will have no effect even if the given time condition would not -have been met. \fIcurl_easy_getinfo(3)\fP with the -\fICURLINFO_CONDITION_UNMET\fP option can be used after a transfer to learn if -a zero-byte successful "transfer" was due to this condition not matching. -.IP CURLOPT_TIMEVALUE -Pass a long as parameter. This should be the time in seconds since 1 Jan 1970, -and the time will be used in a condition as specified with -\fICURLOPT_TIMECONDITION\fP. -.SH CONNECTION OPTIONS -.IP CURLOPT_TIMEOUT -Pass a long as parameter containing the maximum time in seconds that you allow -the libcurl transfer operation to take. Normally, name lookups can take a -considerable time and limiting operations to less than a few minutes risk -aborting perfectly normal operations. This option will cause curl to use the -SIGALRM to enable time-outing system calls. - -In unix-like systems, this might cause signals to be used unless -\fICURLOPT_NOSIGNAL\fP is set. - -Default timeout is 0 (zero) which means it never times out. -.IP CURLOPT_TIMEOUT_MS -Like \fICURLOPT_TIMEOUT\fP but takes number of milliseconds instead. If -libcurl is built to use the standard system name resolver, that portion -of the transfer will still use full-second resolution for timeouts with -a minimum timeout allowed of one second. -(Added in 7.16.2) -.IP CURLOPT_LOW_SPEED_LIMIT -Pass a long as parameter. It contains the transfer speed in bytes per second -that the transfer should be below during \fICURLOPT_LOW_SPEED_TIME\fP seconds -for the library to consider it too slow and abort. -.IP CURLOPT_LOW_SPEED_TIME -Pass a long as parameter. It contains the time in seconds that the transfer -should be below the \fICURLOPT_LOW_SPEED_LIMIT\fP for the library to consider -it too slow and abort. -.IP CURLOPT_MAX_SEND_SPEED_LARGE -Pass a curl_off_t as parameter. If an upload exceeds this speed (counted in -bytes per second) on cumulative average during the transfer, the transfer will -pause to keep the average rate less than or equal to the parameter value. -Defaults to unlimited speed. (Added in 7.15.5) -.IP CURLOPT_MAX_RECV_SPEED_LARGE -Pass a curl_off_t as parameter. If a download exceeds this speed (counted in -bytes per second) on cumulative average during the transfer, the transfer will -pause to keep the average rate less than or equal to the parameter -value. Defaults to unlimited speed. (Added in 7.15.5) -.IP CURLOPT_MAXCONNECTS -Pass a long. The set number will be the persistent connection cache size. The -set amount will be the maximum amount of simultaneously open connections that -libcurl may cache in this easy handle. Default is 5, and there isn't much -point in changing this value unless you are perfectly aware of how this works -and changes libcurl's behaviour. This concerns connections using any of the -protocols that support persistent connections. - -When reaching the maximum limit, curl closes the oldest one in the cache to -prevent increasing the number of open connections. - -If you already have performed transfers with this curl handle, setting a -smaller MAXCONNECTS than before may cause open connections to get closed -unnecessarily. - -If you add this easy handle to a multi handle, this setting is not -acknowledged, and you must instead use \fIcurl_multi_setopt(3)\fP and the -\fICURLMOPT_MAXCONNECTS\fP option. -.IP CURLOPT_CLOSEPOLICY -(Obsolete) This option does nothing. -.IP CURLOPT_FRESH_CONNECT -Pass a long. Set to 1 to make the next transfer use a new (fresh) connection -by force. If the connection cache is full before this connection, one of the -existing connections will be closed as according to the selected or default -policy. This option should be used with caution and only if you understand -what it does. Set this to 0 to have libcurl attempt re-using an existing -connection (default behavior). -.IP CURLOPT_FORBID_REUSE -Pass a long. Set to 1 to make the next transfer explicitly close the -connection when done. Normally, libcurl keeps all connections alive when done -with one transfer in case a succeeding one follows that can re-use them. -This option should be used with caution and only if you understand what it -does. Set to 0 to have libcurl keep the connection open for possible later -re-use (default behavior). -.IP CURLOPT_CONNECTTIMEOUT -Pass a long. It should contain the maximum time in seconds that you allow the -connection to the server to take. This only limits the connection phase, once -it has connected, this option is of no more use. Set to zero to switch to the -default built-in connection timeout - 300 seconds. See also the -\fICURLOPT_TIMEOUT\fP option. - -In unix-like systems, this might cause signals to be used unless -\fICURLOPT_NOSIGNAL\fP is set. -.IP CURLOPT_CONNECTTIMEOUT_MS -Like \fICURLOPT_CONNECTTIMEOUT\fP but takes the number of milliseconds -instead. If libcurl is built to use the standard system name resolver, -that portion of the connect will still use full-second resolution for -timeouts with a minimum timeout allowed of one second. -(Added in 7.16.2) -.IP CURLOPT_IPRESOLVE -Allows an application to select what kind of IP addresses to use when -resolving host names. This is only interesting when using host names that -resolve addresses using more than one version of IP. The allowed values are: -.RS -.IP CURL_IPRESOLVE_WHATEVER -Default, resolves addresses to all IP versions that your system allows. -.IP CURL_IPRESOLVE_V4 -Resolve to IPv4 addresses. -.IP CURL_IPRESOLVE_V6 -Resolve to IPv6 addresses. -.RE -.IP CURLOPT_CONNECT_ONLY -Pass a long. If the parameter equals 1, it tells the library to perform all -the required proxy authentication and connection setup, but no data transfer. -This option is implemented for HTTP, SMTP and POP3. - -The option can be used to simply test a connection to a server, but is more -useful when used with the \fICURLINFO_LASTSOCKET\fP option to -\fIcurl_easy_getinfo(3)\fP as the library can set up the connection and then -the application can obtain the most recently used socket for special data -transfers. (Added in 7.15.2) -.IP CURLOPT_USE_SSL -Pass a long using one of the values from below, to make libcurl use your -desired level of SSL for the transfer. (Added in 7.11.0) - -This is for enabling SSL/TLS when you use FTP, SMTP, POP3, IMAP etc. - -(This option was known as CURLOPT_FTP_SSL up to 7.16.4, and the constants -were known as CURLFTPSSL_*) -.RS -.IP CURLUSESSL_NONE -Don't attempt to use SSL. -.IP CURLUSESSL_TRY -Try using SSL, proceed as normal otherwise. -.IP CURLUSESSL_CONTROL -Require SSL for the control connection or fail with \fICURLE_USE_SSL_FAILED\fP. -.IP CURLUSESSL_ALL -Require SSL for all communication or fail with \fICURLE_USE_SSL_FAILED\fP. -.RE -.IP CURLOPT_RESOLVE -Pass a pointer to a linked list of strings with host name resolve information -to use for requests with this handle. The linked list should be a fully valid -list of \fBstruct curl_slist\fP structs properly filled in. Use -\fIcurl_slist_append(3)\fP to create the list and \fIcurl_slist_free_all(3)\fP -to clean up an entire list. - -Each single name resolve string should be written using the format -HOST:PORT:ADDRESS where HOST is the name libcurl will try to resolve, PORT is -the port number of the service where libcurl wants to connect to the HOST and -ADDRESS is the numerical IP address. If libcurl is built to support IPv6, -ADDRESS can of course be either IPv4 or IPv6 style addressing. - -This option effectively pre-populates the DNS cache with entries for the -host+port pair so redirects and everything that operations against the -HOST+PORT will instead use your provided ADDRESS. - -You can remove names from the DNS cache again, to stop providing these fake -resolves, by including a string in the linked list that uses the format -\&"-HOST:PORT". The host name must be prefixed with a dash, and the host name -and port number must exactly match what was already added previously. - -(Added in 7.21.3) -.IP CURLOPT_DNS_SERVERS -Set the list of DNS servers to be used instead of the system default. -The format of the dns servers option is: - -host[:port][,host[:port]]... - -For example: - -192.168.1.100,192.168.1.101,3.4.5.6 - -This option requires that libcurl was built with a resolver backend that -supports this operation. The c-ares backend is the only such one. - -(Added in 7.24.0) -.IP CURLOPT_ACCEPTTIMEOUT_MS -Pass a long telling libcurl the maximum number of milliseconds to wait for a -server to connect back to libcurl when an active FTP connection is used. If no -timeout is set, the internal default of 60000 will be used. (Added in 7.24.0) -.SH SSL and SECURITY OPTIONS -.IP CURLOPT_SSLCERT -Pass a pointer to a zero terminated string as parameter. The string should be -the file name of your certificate. The default format is "PEM" and can be -changed with \fICURLOPT_SSLCERTTYPE\fP. - -With NSS this can also be the nickname of the certificate you wish to -authenticate with. If you want to use a file from the current directory, please -precede it with "./" prefix, in order to avoid confusion with a nickname. -.IP CURLOPT_SSLCERTTYPE -Pass a pointer to a zero terminated string as parameter. The string should be -the format of your certificate. Supported formats are "PEM" and "DER". (Added -in 7.9.3) -.IP CURLOPT_SSLKEY -Pass a pointer to a zero terminated string as parameter. The string should be -the file name of your private key. The default format is "PEM" and can be -changed with \fICURLOPT_SSLKEYTYPE\fP. -.IP CURLOPT_SSLKEYTYPE -Pass a pointer to a zero terminated string as parameter. The string should be -the format of your private key. Supported formats are "PEM", "DER" and "ENG". - -The format "ENG" enables you to load the private key from a crypto engine. In -this case \fICURLOPT_SSLKEY\fP is used as an identifier passed to the -engine. You have to set the crypto engine with \fICURLOPT_SSLENGINE\fP. -\&"DER" format key file currently does not work because of a bug in OpenSSL. -.IP CURLOPT_KEYPASSWD -Pass a pointer to a zero terminated string as parameter. It will be used as -the password required to use the \fICURLOPT_SSLKEY\fP or -\fICURLOPT_SSH_PRIVATE_KEYFILE\fP private key. -You never needed a pass phrase to load a certificate but you need one to -load your private key. - -(This option was known as CURLOPT_SSLKEYPASSWD up to 7.16.4 and -CURLOPT_SSLCERTPASSWD up to 7.9.2) -.IP CURLOPT_SSLENGINE -Pass a pointer to a zero terminated string as parameter. It will be used as -the identifier for the crypto engine you want to use for your private -key. - -If the crypto device cannot be loaded, \fICURLE_SSL_ENGINE_NOTFOUND\fP is -returned. -.IP CURLOPT_SSLENGINE_DEFAULT -Sets the actual crypto engine as the default for (asymmetric) crypto -operations. - -If the crypto device cannot be set, \fICURLE_SSL_ENGINE_SETFAILED\fP is -returned. - -Even though this option doesn't need any parameter, in some configurations -\fIcurl_easy_setopt\fP might be defined as a macro taking exactly three -arguments. Therefore, it's recommended to pass 1 as parameter to this option. -.IP CURLOPT_SSLVERSION -Pass a long as parameter to control what version of SSL/TLS to attempt to use. -The available options are: -.RS -.IP CURL_SSLVERSION_DEFAULT -The default action. This will attempt to figure out the remote SSL protocol -version, i.e. either SSLv3 or TLSv1 (but not SSLv2, which became disabled -by default with 7.18.1). -.IP CURL_SSLVERSION_TLSv1 -Force TLSv1 -.IP CURL_SSLVERSION_SSLv2 -Force SSLv2 -.IP CURL_SSLVERSION_SSLv3 -Force SSLv3 -.RE -.IP CURLOPT_SSL_VERIFYPEER -Pass a long as parameter. By default, curl assumes a value of 1. - -This option determines whether curl verifies the authenticity of the peer's -certificate. A value of 1 means curl verifies; 0 (zero) means it doesn't. - -When negotiating a SSL connection, the server sends a certificate indicating -its identity. Curl verifies whether the certificate is authentic, i.e. that -you can trust that the server is who the certificate says it is. This trust -is based on a chain of digital signatures, rooted in certification authority -(CA) certificates you supply. curl uses a default bundle of CA certificates -(the path for that is determined at build time) and you can specify alternate -certificates with the \fICURLOPT_CAINFO\fP option or the \fICURLOPT_CAPATH\fP -option. - -When \fICURLOPT_SSL_VERIFYPEER\fP is nonzero, and the verification fails to -prove that the certificate is authentic, the connection fails. When the -option is zero, the peer certificate verification succeeds regardless. - -Authenticating the certificate is not by itself very useful. You typically -want to ensure that the server, as authentically identified by its -certificate, is the server you mean to be talking to. Use -\fICURLOPT_SSL_VERIFYHOST\fP to control that. The check that the host name in -the certificate is valid for the host name you're connecting to is done -independently of the \fICURLOPT_SSL_VERIFYPEER\fP option. -.IP CURLOPT_CAINFO -Pass a char * to a zero terminated string naming a file holding one or more -certificates to verify the peer with. This makes sense only when used in -combination with the \fICURLOPT_SSL_VERIFYPEER\fP option. If -\fICURLOPT_SSL_VERIFYPEER\fP is zero, \fICURLOPT_CAINFO\fP need not -even indicate an accessible file. - -This option is by default set to the system path where libcurl's cacert bundle -is assumed to be stored, as established at build time. - -If curl is built against the NSS SSL library, the NSS PEM PKCS#11 module -(libnsspem.so) needs to be available for this option to work properly. -.IP CURLOPT_ISSUERCERT -Pass a char * to a zero terminated string naming a file holding a CA -certificate in PEM format. If the option is set, an additional check against -the peer certificate is performed to verify the issuer is indeed the one -associated with the certificate provided by the option. This additional check -is useful in multi-level PKI where one needs to enforce that the peer -certificate is from a specific branch of the tree. - -This option makes sense only when used in combination with the -\fICURLOPT_SSL_VERIFYPEER\fP option. Otherwise, the result of the check is not -considered as failure. - -A specific error code (CURLE_SSL_ISSUER_ERROR) is defined with the option, -which is returned if the setup of the SSL/TLS session has failed due to a -mismatch with the issuer of peer certificate (\fICURLOPT_SSL_VERIFYPEER\fP has -to be set too for the check to fail). (Added in 7.19.0) -.IP CURLOPT_CAPATH -Pass a char * to a zero terminated string naming a directory holding multiple -CA certificates to verify the peer with. If libcurl is built against OpenSSL, -the certificate directory must be prepared using the openssl c_rehash utility. -This makes sense only when used in combination with the -\fICURLOPT_SSL_VERIFYPEER\fP option. If \fICURLOPT_SSL_VERIFYPEER\fP is zero, -\fICURLOPT_CAPATH\fP need not even indicate an accessible path. The -\fICURLOPT_CAPATH\fP function apparently does not work in Windows due to some -limitation in openssl. This option is OpenSSL-specific and does nothing if -libcurl is built to use GnuTLS. NSS-powered libcurl provides the option only -for backward compatibility. -.IP CURLOPT_CRLFILE -Pass a char * to a zero terminated string naming a file with the concatenation -of CRL (in PEM format) to use in the certificate validation that occurs during -the SSL exchange. - -When curl is built to use NSS or GnuTLS, there is no way to influence the use -of CRL passed to help in the verification process. When libcurl is built with -OpenSSL support, X509_V_FLAG_CRL_CHECK and X509_V_FLAG_CRL_CHECK_ALL are both -set, requiring CRL check against all the elements of the certificate chain if -a CRL file is passed. - -This option makes sense only when used in combination with the -\fICURLOPT_SSL_VERIFYPEER\fP option. - -A specific error code (CURLE_SSL_CRL_BADFILE) is defined with the option. It -is returned when the SSL exchange fails because the CRL file cannot be loaded. -A failure in certificate verification due to a revocation information found in -the CRL does not trigger this specific error. (Added in 7.19.0) -.IP CURLOPT_SSL_VERIFYHOST -Pass a long as parameter. - -This option determines whether libcurl verifies that the server cert is for -the server it is known as. - -When negotiating a SSL connection, the server sends a certificate indicating -its identity. - -When \fICURLOPT_SSL_VERIFYHOST\fP is 2, that certificate must indicate that -the server is the server to which you meant to connect, or the connection -fails. - -Curl considers the server the intended one when the Common Name field or a -Subject Alternate Name field in the certificate matches the host name in the -URL to which you told Curl to connect. - -When the value is 1, libcurl will return a failure. It was previously (in -7.28.0 and earlier) a debug option of some sorts, but it is no longer -supported due to frequently leading to programmer mistakes. - -When the value is 0, the connection succeeds regardless of the names in the -certificate. - -The default value for this option is 2. - -This option controls checking the server's certificate's claimed identity. -The server could be lying. To control lying, see -\fICURLOPT_SSL_VERIFYPEER\fP. If libcurl is built against NSS and -\fICURLOPT_SSL_VERIFYPEER\fP is zero, \fICURLOPT_SSL_VERIFYHOST\fP -is ignored. - -.IP CURLOPT_CERTINFO -Pass a long set to 1 to enable libcurl's certificate chain info gatherer. With -this enabled, libcurl (if built with OpenSSL) will extract lots of information -and data about the certificates in the certificate chain used in the SSL -connection. This data is then possible to extract after a transfer using -\fIcurl_easy_getinfo(3)\fP and its option \fICURLINFO_CERTINFO\fP. (Added in -7.19.1) -.IP CURLOPT_RANDOM_FILE -Pass a char * to a zero terminated file name. The file will be used to read -from to seed the random engine for SSL. The more random the specified file is, -the more secure the SSL connection will become. -.IP CURLOPT_EGDSOCKET -Pass a char * to the zero terminated path name to the Entropy Gathering Daemon -socket. It will be used to seed the random engine for SSL. -.IP CURLOPT_SSL_CIPHER_LIST -Pass a char *, pointing to a zero terminated string holding the list of -ciphers to use for the SSL connection. The list must be syntactically correct, -it consists of one or more cipher strings separated by colons. Commas or -spaces are also acceptable separators but colons are normally used, \&!, \&- -and \&+ can be used as operators. - -For OpenSSL and GnuTLS valid examples of cipher lists include 'RC4-SHA', -\'SHA1+DES\', 'TLSv1' and 'DEFAULT'. The default list is normally set when you -compile OpenSSL. - -You'll find more details about cipher lists on this URL: -\fIhttp://www.openssl.org/docs/apps/ciphers.html\fP - -For NSS, valid examples of cipher lists include 'rsa_rc4_128_md5', -\'rsa_aes_128_sha\', etc. With NSS you don't add/remove ciphers. If one uses -this option then all known ciphers are disabled and only those passed in -are enabled. - -You'll find more details about the NSS cipher lists on this URL: -\fIhttp://git.fedorahosted.org/cgit/mod_nss.git/plain/docs/mod_nss.html#Directives\fP - -.IP CURLOPT_SSL_SESSIONID_CACHE -Pass a long set to 0 to disable libcurl's use of SSL session-ID caching. Set -this to 1 to enable it. By default all transfers are done using the -cache. While nothing ever should get hurt by attempting to reuse SSL -session-IDs, there seem to be broken SSL implementations in the wild that may -require you to disable this in order for you to succeed. (Added in 7.16.0) -.IP CURLOPT_SSL_OPTIONS -Pass a long with a bitmask to tell libcurl about specific SSL behaviors. - -CURLSSLOPT_ALLOW_BEAST is the only supported bit and by setting this the user -will tell libcurl to not attempt to use any workarounds for a security flaw -in the SSL3 and TLS1.0 protocols. If this option isn't used or this bit is -set to 0, the SSL layer libcurl uses may use a work-around for this flaw -although it might cause interoperability problems with some (older) SSL -implementations. WARNING: avoiding this work-around loosens the security, and -by setting this option to 1 you ask for exactly that. (Added in 7.25.0) -.IP CURLOPT_KRBLEVEL -Pass a char * as parameter. Set the kerberos security level for FTP; this also -enables kerberos awareness. This is a string, \&'clear', \&'safe', -\&'confidential' or \&'private'. If the string is set but doesn't match one -of these, 'private' will be used.

Set CURLSSH_AUTH_ANY to let -libcurl pick a suitable one. Currently CURLSSH_AUTH_HOST has no effect. (Added -in 7.16.1) If CURLSSH_AUTH_AGENT is used, libcurl attempts to connect to -ssh-agent or pageant and let the agent attempt the authentication. (Added in -7.28.0) -.IP CURLOPT_SSH_HOST_PUBLIC_KEY_MD5 -Pass a char * pointing to a string containing 32 hexadecimal digits. The -string should be the 128 bit MD5 checksum of the remote host's public key, and -libcurl will reject the connection to the host unless the md5sums match. This -option is only for SCP and SFTP transfers. (Added in 7.17.1) -.IP CURLOPT_SSH_PUBLIC_KEYFILE -Pass a char * pointing to a file name for your public key. If not used, -libcurl defaults to \fB$HOME/.ssh/id_dsa.pub\fP if the HOME environment -variable is set, and just "id_dsa.pub" in the current directory if HOME is not -set. (Added in 7.16.1) -If an empty string is passed, libcurl will pass no public key to libssh2 -which then tries to compute it from the private key, this is known to work -when libssh2 1.4.0+ is linked against OpenSSL. (Added in 7.26.0) -.IP CURLOPT_SSH_PRIVATE_KEYFILE -Pass a char * pointing to a file name for your private key. If not used, -libcurl defaults to \fB$HOME/.ssh/id_dsa\fP if the HOME environment variable -is set, and just "id_dsa" in the current directory if HOME is not set. If the -file is password-protected, set the password with -\fICURLOPT_KEYPASSWD\fP. (Added in 7.16.1) -.IP CURLOPT_SSH_KNOWNHOSTS -Pass a pointer to a zero terminated string holding the file name of the -known_host file to use. The known_hosts file should use the OpenSSH file -format as supported by libssh2. If this file is specified, libcurl will only -accept connections with hosts that are known and present in that file, with a -matching public key.

This will also add the host+key combo -to the known_host pool kept in memory if it wasn't already present there. The -adding of data to the file is done by completely replacing the file with a new -copy, so the permissions of the file must allow this. -.IP CURLKHSTAT_FINE -The host+key is accepted libcurl will continue with the connection. This will -also add the host+key combo to the known_host pool kept in memory if it wasn't -already present there. -.IP CURLKHSTAT_REJECT -The host+key is rejected. libcurl will deny the connection to continue and it -will be closed. -.IP CURLKHSTAT_DEFER -The host+key is rejected, but the SSH connection is asked to be kept alive. -This feature could be used when the app wants to somehow return back and act -on the host+key situation and then retry without needing the overhead of -setting it up from scratch again. -.RE - (Added in 7.19.6) -.IP CURLOPT_SSH_KEYDATA -Pass a void * as parameter. This pointer will be passed along verbatim to the -callback set with \fICURLOPT_SSH_KEYFUNCTION\fP. (Added in 7.19.6) -.SH OTHER OPTIONS -.IP CURLOPT_PRIVATE -Pass a void * as parameter, pointing to data that should be associated with -this curl handle. The pointer can subsequently be retrieved using -\fIcurl_easy_getinfo(3)\fP with the CURLINFO_PRIVATE option. libcurl itself -does nothing with this data. (Added in 7.10.3) -.IP CURLOPT_SHARE -Pass a share handle as a parameter. The share handle must have been created by -a previous call to \fIcurl_share_init(3)\fP. Setting this option, will make -this curl handle use the data from the shared handle instead of keeping the -data to itself. This enables several curl handles to share data. If the curl -handles are used simultaneously in multiple threads, you \fBMUST\fP use the -locking methods in the share handle. See \fIcurl_share_setopt(3)\fP for -details. - -If you add a share that is set to share cookies, your easy handle will use -that cookie cache and get the cookie engine enabled. If you unshare an object -that was using cookies (or change to another object that doesn't share -cookies), the easy handle will get its cookie engine disabled. - -Data that the share object is not set to share will be dealt with the usual -way, as if no share was used. -.IP CURLOPT_NEW_FILE_PERMS -Pass a long as a parameter, containing the value of the permissions that will -be assigned to newly created files on the remote server. The default value is -\fI0644\fP, but any valid value can be used. The only protocols that can use -this are \fIsftp://\fP, \fIscp://\fP, and \fIfile://\fP. (Added in 7.16.4) -.IP CURLOPT_NEW_DIRECTORY_PERMS -Pass a long as a parameter, containing the value of the permissions that will -be assigned to newly created directories on the remote server. The default -value is \fI0755\fP, but any valid value can be used.

Append one section -at a time until you've added all the sections you want included and then you -pass the \fIfirstitem\fP pointer as parameter to \fBCURLOPT_HTTPPOST\fP. -\fIlastitem\fP is set after each \fIcurl_formadd(3)\fP call and on repeated -invokes it should be left as set to allow repeated invokes to find the end of -the list faster. - -After the \fIlastitem\fP pointer follow the real arguments. - -The pointers \fIfirstitem\fP and \fIlastitem\fP should both be pointing to -NULL in the first call to this function. All list-data will be allocated by -the function itself. You must call \fIcurl_formfree(3)\fP on the -\fIfirstitem\P after the form post has been done to free the resources. - -Using POST with HTTP 1.1 implies the use of a "Expect: 100-continue" header. -You can disable this header with \fICURLOPT_HTTPHEADER\fP as usual. - -First, there are some basics you need to understand about multipart/formdata -posts. Each part consists of at least a NAME and a CONTENTS part. If the part -is made for file upload, there are also a stored CONTENT-TYPE and a FILENAME. -Below, we'll discuss what options you use to set these properties in the -parts you want to add to your post. - -The options listed first are for making normal parts. The options from -\fICURLFORM_FILE\fP through \fICURLFORM_BUFFERLENGTH\fP are for file upload -parts. -.SH OPTIONS -.IP CURLFORM_COPYNAME -followed by a string which provides the \fIname\fP of this part. libcurl -copies the string so your application doesn't need to keep it around after -this function call. If the name isn't NUL-terminated, or if you'd -like it to contain zero bytes, you must set its length with -\fBCURLFORM_NAMELENGTH\fP. The copied data will be freed by -\fIcurl_formfree(3)\fP. -.IP CURLFORM_PTRNAME -followed by a string which provides the \fIname\fP of this part. libcurl -will use the pointer and refer to the data in your application, so you -must make sure it remains until curl no longer needs it. If the name -isn't NUL-terminated, or if you'd like it to contain zero -bytes, you must set its length with \fBCURLFORM_NAMELENGTH\fP. -.IP CURLFORM_COPYCONTENTS -followed by a pointer to the contents of this part, the actual data -to send away. libcurl copies the provided data, so your application doesn't -need to keep it around after this function call. If the data isn't null -terminated, or if you'd like it to contain zero bytes, you must -set the length of the name with \fBCURLFORM_CONTENTSLENGTH\fP. The copied -data will be freed by \fIcurl_formfree(3)\fP. -.IP CURLFORM_PTRCONTENTS -followed by a pointer to the contents of this part, the actual data -to send away. libcurl will use the pointer and refer to the data in your -application, so you must make sure it remains until curl no longer needs it. -If the data isn't NUL-terminated, or if you'd like it to contain zero bytes, -you must set its length with \fBCURLFORM_CONTENTSLENGTH\fP. -.IP CURLFORM_CONTENTSLENGTH -followed by a long giving the length of the contents. Note that for -\fICURLFORM_STREAM\fP contents, this option is mandatory. -.IP CURLFORM_FILECONTENT -followed by a filename, causes that file to be read and its contents used -as data in this part. This part does \fInot\fP automatically become a file -upload part simply because its data was read from a file. -.IP CURLFORM_FILE -followed by a filename, makes this part a file upload part. It sets the -\fIfilename\fP field to the basename of the provided filename, it reads the -contents of the file and passes them as data and sets the content-type if the -given file match one of the internally known file extensions. For -\fBCURLFORM_FILE\fP the user may send one or more files in one part by -providing multiple \fBCURLFORM_FILE\fP arguments each followed by the filename -(and each \fICURLFORM_FILE\fP is allowed to have a -\fICURLFORM_CONTENTTYPE\fP). -.IP CURLFORM_CONTENTTYPE -is used in combination with \fICURLFORM_FILE\fP. Followed by a pointer to a -string which provides the content-type for this part, possibly instead of an -internally chosen one. -.IP CURLFORM_FILENAME -is used in combination with \fICURLFORM_FILE\fP. Followed by a pointer to a -string, it tells libcurl to use the given string as the \fIfilename\fP in the -file upload part instead of the actual file name. -.IP CURLFORM_BUFFER -is used for custom file upload parts without use of \fICURLFORM_FILE\fP. It -tells libcurl that the file contents are already present in a buffer. The -parameter is a string which provides the \fIfilename\fP field in the content -header. -.IP CURLFORM_BUFFERPTR -is used in combination with \fICURLFORM_BUFFER\fP. The parameter is a pointer -to the buffer to be uploaded. This buffer must not be freed until after -\fIcurl_easy_cleanup(3)\fP is called. You must also use -\fICURLFORM_BUFFERLENGTH\fP to set the number of bytes in the buffer. -.IP CURLFORM_BUFFERLENGTH -is used in combination with \fICURLFORM_BUFFER\fP. The parameter is a -long which gives the length of the buffer. -.IP CURLFORM_STREAM -Tells libcurl to use the \fICURLOPT_READFUNCTION\fP callback to get data. The -parameter you pass to \fICURLFORM_STREAM\fP is the pointer passed on to the -read callback's fourth argument. If you want the part to look like a file -upload one, set the \fICURLFORM_FILENAME\fP parameter as well. Note that when -using \fICURLFORM_STREAM\fP, \fICURLFORM_CONTENTSLENGTH\fP must also be set -with the total expected length of the part. (Option added in libcurl 7.18.2) -.IP CURLFORM_ARRAY -Another possibility to send options to curl_formadd() is the -\fBCURLFORM_ARRAY\fP option, that passes a struct curl_forms array pointer as -its value. Each curl_forms structure element has a CURLformoption and a char -pointer. The final element in the array must be a CURLFORM_END. All available -options can be used in an array, except the CURLFORM_ARRAY option itself! The -last argument in such an array must always be \fBCURLFORM_END\fP. -.IP CURLFORM_CONTENTHEADER -specifies extra headers for the form POST section. This takes a curl_slist -prepared in the usual way using \fBcurl_slist_append\fP and appends the list -of headers to those libcurl automatically generates. The list must exist while -the POST occurs, if you free it before the post completes you may experience -problems. - -When you've passed the HttpPost pointer to \fIcurl_easy_setopt(3)\fP (using -the \fICURLOPT_HTTPPOST\fP option), you must not free the list until after -you've called \fIcurl_easy_cleanup(3)\fP for the curl handle. - -See example below. -.SH RETURN VALUE -0 means everything was ok, non-zero means an error occurred corresponding -to a CURL_FORMADD_* constant defined in -.I <curl/curl.h> -.SH EXAMPLE -.nf - - struct curl_httppost* post = NULL;

The \fIcurl_multi_socket_action(3)\fP function informs the -application about updates in the socket (file descriptor) status by doing -none, one, or multiple calls to the curl_socket_callback given in the -\fBparam\fP argument. They update the status with changes since the previous -time a \fIcurl_multi_socket(3)\fP function was called. If the given callback -pointer is NULL, no callback will be called.

Enabling pipelining on a multi -handle will make it attempt to perform HTTP Pipelining as far as possible for -transfers using this handle.

A timeout value of -1 means -that there is no timeout at all, and 0 means that the timeout is already -reached.

Proceed as usual. -.IP "CURLE_UNSUPPORTED_PROTOCOL (1)" -The URL you passed to libcurl used a protocol that this libcurl does not -support. The support might be a compile-time option that you didn't use, it -can be a misspelled protocol string or just a protocol libcurl has no code -for. -.IP "CURLE_FAILED_INIT (2)" -Very early initialization code failed. This is likely to be an internal error -or problem, or a resource problem where something fundamental couldn't get -done at init time. -.IP "CURLE_URL_MALFORMAT (3)" -The URL was not properly formatted. -.IP "CURLE_NOT_BUILT_IN (4)" -A requested feature, protocol or option was not found built-in in this libcurl -due to a build-time decision. This means that a feature or option was not -enabled or explicitly disabled when libcurl was built and in order to get it -to function you have to get a rebuilt libcurl. -.IP "CURLE_COULDNT_RESOLVE_PROXY (5)" -Couldn't resolve proxy. The given proxy host could not be resolved. -.IP "CURLE_COULDNT_RESOLVE_HOST (6)" -Couldn't resolve host. The given remote host was not resolved. -.IP "CURLE_COULDNT_CONNECT (7)" -Failed to connect() to host or proxy. -.IP "CURLE_FTP_WEIRD_SERVER_REPLY (8)" -After connecting to a FTP server, libcurl expects to get a certain reply -back. This error code implies that it got a strange or bad reply. The given -remote server is probably not an OK FTP server. -.IP "CURLE_REMOTE_ACCESS_DENIED (9)" -We were denied access to the resource given in the URL. For FTP, this occurs -while trying to change to the remote directory. -.IP "CURLE_FTP_ACCEPT_FAILED (10)" -While waiting for the server to connect back when an active FTP session is -used, an error code was sent over the control connection or similar. -.IP "CURLE_FTP_WEIRD_PASS_REPLY (11)" -After having sent the FTP password to the server, libcurl expects a proper -reply. This error code indicates that an unexpected code was returned. -.IP "CURLE_FTP_ACCEPT_TIMEOUT (12)" -During an active FTP session while waiting for the server to connect, the -\fICURLOPT_ACCEPTTIMOUT_MS\fP (or the internal default) timeout expired. -.IP "CURLE_FTP_WEIRD_PASV_REPLY (13)" -libcurl failed to get a sensible result back from the server as a response to -either a PASV or a EPSV command. The server is flawed. -.IP "CURLE_FTP_WEIRD_227_FORMAT (14)" -FTP servers return a 227-line as a response to a PASV command. If libcurl -fails to parse that line, this return code is passed back. -.IP "CURLE_FTP_CANT_GET_HOST (15)" -An internal failure to lookup the host used for the new connection. -.IP "CURLE_FTP_COULDNT_SET_TYPE (17)" -Received an error when trying to set the transfer mode to binary or ASCII. -.IP "CURLE_PARTIAL_FILE (18)" -A file transfer was shorter or larger than expected. This happens when the -server first reports an expected transfer size, and then delivers data that -doesn't match the previously given size. -.IP "CURLE_FTP_COULDNT_RETR_FILE (19)" -This was either a weird reply to a 'RETR' command or a zero byte transfer -complete. -.IP "CURLE_QUOTE_ERROR (21)" -When sending custom "QUOTE" commands to the remote server, one of the commands -returned an error code that was 400 or higher (for FTP) or otherwise -indicated unsuccessful completion of the command. -.IP "CURLE_HTTP_RETURNED_ERROR (22)" -This is returned if CURLOPT_FAILONERROR is set TRUE and the HTTP server -returns an error code that is >= 400. -.IP "CURLE_WRITE_ERROR (23)" -An error occurred when writing received data to a local file, or an error was -returned to libcurl from a write callback. -.IP "CURLE_UPLOAD_FAILED (25)" -Failed starting the upload. For FTP, the server typically denied the STOR -command. The error buffer usually contains the server's explanation for this. -.IP "CURLE_READ_ERROR (26)" -There was a problem reading a local file or an error returned by the read -callback. -.IP "CURLE_OUT_OF_MEMORY (27)" -A memory allocation request failed.

The specified time-out period was reached according to the -conditions. -.IP "CURLE_FTP_PORT_FAILED (30)" -The FTP PORT command returned error. This mostly happens when you haven't -specified a good enough address for libcurl to use. See \fICURLOPT_FTPPORT\fP. -.IP "CURLE_FTP_COULDNT_USE_REST (31)" -The FTP REST command returned error.

There are specific man pages for each function mentioned in -here. There's also the \fIlibcurl-tutorial(3)\fP man page for a complete -tutorial to programming with libcurl and the \fIlibcurl-easy(3)\fP man page -for an overview of the libcurl easy interface. - -All functions in the multi interface are prefixed with curl_multi. -.SH "OBJECTIVES" -The multi interface offers several abilities that the easy interface doesn't. -They are mainly: - -1. Enable a "pull" interface. The application that uses libcurl decides where -and when to ask libcurl to get/send data. - -2. Enable multiple simultaneous transfers in the same thread without making it -complicated for the application. - -3. Enable the application to wait for action on its own file descriptors and -curl's file descriptors simultaneous easily. -.SH "ONE MULTI HANDLE MANY EASY HANDLES" -To use the multi interface, you must first create a 'multi handle' with -\fIcurl_multi_init(3)\fP. This handle is then used as input to all further -curl_multi_* functions. - -Each single transfer is built up with an easy handle. You must create them, -and setup the appropriate options for each easy handle, as outlined in the -\fIlibcurl(3)\fP man page, using \fIcurl_easy_setopt(3)\fP. - -When the easy handle is setup for a transfer, then instead of using -\fIcurl_easy_perform(3)\fP (as when using the easy interface for transfers), -you should instead add the easy handle to the multi handle using -\fIcurl_multi_add_handle(3)\fP. The multi handle is sometimes referred to as a -\'multi stack\' because of the fact that it may hold a large amount of easy -handles. - -Should you change your mind, the easy handle is again removed from the multi -stack using \fIcurl_multi_remove_handle(3)\fP. Once removed from the multi -handle, you can again use other easy interface functions like -\fIcurl_easy_perform(3)\fP on the handle or whatever you think is necessary. - -Adding the easy handle to the multi handle does not start the transfer. -Remember that one of the main ideas with this interface is to let your -application drive. You drive the transfers by invoking -\fIcurl_multi_perform(3)\fP. libcurl will then transfer data if there is -anything available to transfer. It'll use the callbacks and everything else -you have setup in the individual easy handles. It'll transfer data on all -current transfers in the multi stack that are ready to transfer anything. It -may be all, it may be none. - -Your application can acquire knowledge from libcurl when it would like to get -invoked to transfer data, so that you don't have to busy-loop and call that -\fIcurl_multi_perform(3)\fP like crazy. \fIcurl_multi_fdset(3)\fP offers an -interface using which you can extract fd_sets from libcurl to use in select() -or poll() calls in order to get to know when the transfers in the multi stack -might need attention. This also makes it very easy for your program to wait -for input on your own private file descriptors at the same time or perhaps -timeout every now and then, should you want that. - -\fIcurl_multi_perform(3)\fP stores the number of still running transfers in -one of its input arguments, and by reading that you can figure out when all -the transfers in the multi handles are done. 'done' does not mean -successful. One or more of the transfers may have failed. Tracking when this -number changes, you know when one or more transfers are done. - -To get information about completed transfers, to figure out success or not and -similar, \fIcurl_multi_info_read(3)\fP should be called. It can return a -message about a current or previous transfer. Repeated invokes of the function -get more messages until the message queue is empty. The information you -receive there includes an easy handle pointer which you may use to identify -which easy handle the information regards. - -When a single transfer is completed, the easy handle is still left added to -the multi stack. You need to first remove the easy handle with -\fIcurl_multi_remove_handle(3)\fP and then close it with -\fIcurl_easy_cleanup(3)\fP, or possibly set new options to it and add it again -with \fIcurl_multi_add_handle(3)\fP to start another transfer. - -When all transfers in the multi stack are done, cleanup the multi handle with -\fIcurl_multi_cleanup(3)\fP. Be careful and please note that you \fBMUST\fP -invoke separate \fIcurl_easy_cleanup(3)\fP calls on every single easy handle -to clean them up properly. - -If you want to re-use an easy handle that was added to the multi handle for -transfer, you must first remove it from the multi stack and then re-add it -again (possibly after having altered some options at your own choice). -.SH "MULTI_SOCKET" -\fIcurl_multi_socket_action(3)\fP function offers a way for applications to -not only avoid being forced to use select(), but it also offers a much more -high-performance API that will make a significant difference for applications -using large numbers of simultaneous connections. - -\fIcurl_multi_socket_action(3)\fP is then used instead of -\fIcurl_multi_perform(3)\fP. - -When using this API, you add easy handles to the multi handle just as with the -normal multi interface. Then you also set two callbacks with the -CURLMOPT_SOCKETFUNCTION and CURLMOPT_TIMERFUNCTION options to -\fIcurl_multi_setopt(3)\fP. - -The API is then designed to inform your application about which sockets -libcurl is currently using and for what activities (read and/or write) on -those sockets your application is expected to wait for. - -Your application must then make sure to receive all sockets informed about in -the CURLMOPT_SOCKETFUNCTION callback and make sure it reacts on the given -activity on them. When a socket has the given activity, you call -\fIcurl_multi_socket_action(3)\fP specifying which socket and action there -are. - -The CURLMOPT_TIMERFUNCTION callback is called to set a timeout. When that -timeout expires, your application should call the -\fIcurl_multi_socket_action(3)\fP function saying it was due to a timeout. -.SH "BLOCKING" -A few areas in the code are still using blocking code, even when used from the -multi interface. While we certainly want and intend for these to get fixed in -the future, you should be aware of the following current restrictions: - -.nf - - Name resolves unless the c-ares or threaded-resolver backends are used - - NSS SSL connections - - HTTP proxy CONNECT operations - - SOCKS proxy handshakes - - file:// transfers - - TELNET transfers -.fi diff --git a/plugins/FTPFileYM/curl/docs/libcurl/libcurl-multi.html b/plugins/FTPFileYM/curl/docs/libcurl/libcurl-multi.html deleted file mode 100644 index efcc540265..0000000000 --- a/plugins/FTPFileYM/curl/docs/libcurl/libcurl-multi.html +++ /dev/null @@ -1,78 +0,0 @@ -<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" - "http://www.w3.org/TR/html4/loose.dtd"> -<html><head> -<title>libcurl-multi man page</title> -<meta name="generator" content="roffit"> -<STYLE type="text/css"> -P.level0 { - padding-left: 2em; -} - -P.level1 { - padding-left: 4em; -} - -P.level2 { - padding-left: 6em; -} - -span.emphasis { - font-style: italic; -} - -span.bold { - font-weight: bold; -} - -span.manpage { - font-weight: bold; -} - -h2.nroffsh { - background-color: #e0e0e0; -} - -span.nroffip { - font-weight: bold; - font-size: 120%; - font-family: monospace; -} - -p.roffit { - text-align: center; - font-size: 80%; -} -</STYLE> -</head><body> - -<p class="level0"><a name="NAME"></a><h2 class="nroffsh">NAME</h2> -<p class="level0">libcurl-multi - how to use the multi interface <a name="DESCRIPTION"></a><h2 class="nroffsh">DESCRIPTION</h2> -<p class="level0">This is an overview on how to use the libcurl multi interface in your C programs.

The text will focus -mainly on the C interface but might apply fairly well on other interfaces as -well as they usually follow the C one pretty closely. - -This document will refer to 'the user' as the person writing the source code -that uses libcurl. That would probably be you or someone in your position. -What will be generally referred to as 'the program' will be the collected -source code that you write that is using libcurl for transfers. The program -is outside libcurl and libcurl is outside of the program. - -To get more details on all options and functions described herein, please -refer to their respective man pages. - -.SH "Building" -There are many different ways to build C programs. This chapter will assume a -UNIX-style build process. If you use a different build system, you can still -read this to get general information that may apply to your environment as -well. -.IP "Compiling the Program" -Your compiler needs to know where the libcurl headers are located. Therefore -you must set your compiler's include path to point to the directory where you -installed them. The 'curl-config'[3] tool can be used to get this information: - -$ curl-config --cflags - -.IP "Linking the Program with libcurl" -When having compiled the program, you need to link your object files to create -a single executable. For that to succeed, you need to link with libcurl and -possibly also with other libraries that libcurl itself depends on. Like the -OpenSSL libraries, but even some standard OS libraries may be needed on the -command line. To figure out which flags to use, once again the 'curl-config' -tool comes to the rescue: - -$ curl-config --libs - -.IP "SSL or Not" -libcurl can be built and customized in many ways. One of the things that -varies from different libraries and builds is the support for SSL-based -transfers, like HTTPS and FTPS. If a supported SSL library was detected -properly at build-time, libcurl will be built with SSL support. To figure out -if an installed libcurl has been built with SSL support enabled, use -\&'curl-config' like this: - -$ curl-config --feature - -And if SSL is supported, the keyword 'SSL' will be written to stdout, -possibly together with a few other features that could be either on or off on -for different libcurls. - -See also the "Features libcurl Provides" further down. -.IP "autoconf macro" -When you write your configure script to detect libcurl and setup variables -accordingly, we offer a prewritten macro that probably does everything you -need in this area. See docs/libcurl/libcurl.m4 file - it includes docs on how -to use it. - -.SH "Portable Code in a Portable World" -The people behind libcurl have put a considerable effort to make libcurl work -on a large amount of different operating systems and environments. - -You program libcurl the same way on all platforms that libcurl runs on. There -are only very few minor considerations that differ. If you just make sure to -write your code portable enough, you may very well create yourself a very -portable program. libcurl shouldn't stop you from that. - -.SH "Global Preparation" -The program must initialize some of the libcurl functionality globally. That -means it should be done exactly once, no matter how many times you intend to -use the library. Once for your program's entire life time. This is done using - - curl_global_init() - -and it takes one parameter which is a bit pattern that tells libcurl what to -initialize. Using \fICURL_GLOBAL_ALL\fP will make it initialize all known -internal sub modules, and might be a good default option. The current two bits -that are specified are: -.RS -.IP "CURL_GLOBAL_WIN32" -which only does anything on Windows machines. When used on -a Windows machine, it'll make libcurl initialize the win32 socket -stuff. Without having that initialized properly, your program cannot use -sockets properly. You should only do this once for each application, so if -your program already does this or of another library in use does it, you -should not tell libcurl to do this as well. -.IP CURL_GLOBAL_SSL -which only does anything on libcurls compiled and built SSL-enabled. On these -systems, this will make libcurl initialize the SSL library properly for this -application. This only needs to be done once for each application so if your -program or another library already does this, this bit should not be needed. -.RE - -libcurl has a default protection mechanism that detects if -\fIcurl_global_init(3)\fP hasn't been called by the time -\fIcurl_easy_perform(3)\fP is called and if that is the case, libcurl runs the -function itself with a guessed bit pattern. Please note that depending solely -on this is not considered nice nor very good. - -When the program no longer uses libcurl, it should call -\fIcurl_global_cleanup(3)\fP, which is the opposite of the init call. It will -then do the reversed operations to cleanup the resources the -\fIcurl_global_init(3)\fP call initialized. - -Repeated calls to \fIcurl_global_init(3)\fP and \fIcurl_global_cleanup(3)\fP -should be avoided. They should only be called once each. - -.SH "Features libcurl Provides" -It is considered best-practice to determine libcurl features at run-time -rather than at build-time (if possible of course). By calling -\fIcurl_version_info(3)\fP and checking out the details of the returned -struct, your program can figure out exactly what the currently running libcurl -supports. - -.SH "Handle the Easy libcurl" -libcurl first introduced the so called easy interface. All operations in the -easy interface are prefixed with 'curl_easy'. - -Recent libcurl versions also offer the multi interface. More about that -interface, what it is targeted for and how to use it is detailed in a separate -chapter further down. You still need to understand the easy interface first, -so please continue reading for better understanding. - -To use the easy interface, you must first create yourself an easy handle. You -need one handle for each easy session you want to perform. Basically, you -should use one handle for every thread you plan to use for transferring. You -must never share the same handle in multiple threads. - -Get an easy handle with - - easyhandle = curl_easy_init(); - -It returns an easy handle. Using that you proceed to the next step: setting -up your preferred actions. A handle is just a logic entity for the upcoming -transfer or series of transfers. - -You set properties and options for this handle using -\fIcurl_easy_setopt(3)\fP. They control how the subsequent transfer or -transfers will be made. Options remain set in the handle until set again to -something different. Alas, multiple requests using the same handle will use -the same options. - -Many of the options you set in libcurl are "strings", pointers to data -terminated with a zero byte. When you set strings with -\fIcurl_easy_setopt(3)\fP, libcurl makes its own copy so that they don't -need to be kept around in your application after being set[4]. - -One of the most basic properties to set in the handle is the URL. You set -your preferred URL to transfer with CURLOPT_URL in a manner similar to: - -.nf - curl_easy_setopt(handle, CURLOPT_URL, "http://domain.com/"); -.fi - -Let's assume for a while that you want to receive data as the URL identifies a -remote resource you want to get here. Since you write a sort of application -that needs this transfer, I assume that you would like to get the data passed -to you directly instead of simply getting it passed to stdout. So, you write -your own function that matches this prototype: - - size_t write_data(void *buffer, size_t size, size_t nmemb, void *userp); - -You tell libcurl to pass all data to this function by issuing a function -similar to this: - - curl_easy_setopt(easyhandle, CURLOPT_WRITEFUNCTION, write_data); - -You can control what data your callback function gets in the fourth argument -by setting another property: - - curl_easy_setopt(easyhandle, CURLOPT_WRITEDATA, &internal_struct); - -Using that property, you can easily pass local data between your application -and the function that gets invoked by libcurl. libcurl itself won't touch the -data you pass with \fICURLOPT_WRITEDATA\fP. - -libcurl offers its own default internal callback that will take care of the data -if you don't set the callback with \fICURLOPT_WRITEFUNCTION\fP. It will then -simply output the received data to stdout. You can have the default callback -write the data to a different file handle by passing a 'FILE *' to a file -opened for writing with the \fICURLOPT_WRITEDATA\fP option. - -Now, we need to take a step back and have a deep breath. Here's one of those -rare platform-dependent nitpicks. Did you spot it? On some platforms[2], -libcurl won't be able to operate on files opened by the program. Thus, if you -use the default callback and pass in an open file with -\fICURLOPT_WRITEDATA\fP, it will crash. You should therefore avoid this to -make your program run fine virtually everywhere. - -(\fICURLOPT_WRITEDATA\fP was formerly known as \fICURLOPT_FILE\fP. Both names -still work and do the same thing). - -If you're using libcurl as a win32 DLL, you MUST use the -\fICURLOPT_WRITEFUNCTION\fP if you set \fICURLOPT_WRITEDATA\fP - or you will -experience crashes. - -There are of course many more options you can set, and we'll get back to a few -of them later. Let's instead continue to the actual transfer: - - success = curl_easy_perform(easyhandle); - -\fIcurl_easy_perform(3)\fP will connect to the remote site, do the necessary -commands and receive the transfer. Whenever it receives data, it calls the -callback function we previously set. The function may get one byte at a time, -or it may get many kilobytes at once. libcurl delivers as much as possible as -often as possible. Your callback function should return the number of bytes it -\&"took care of". If that is not the exact same amount of bytes that was -passed to it, libcurl will abort the operation and return with an error code. - -When the transfer is complete, the function returns a return code that informs -you if it succeeded in its mission or not. If a return code isn't enough for -you, you can use the CURLOPT_ERRORBUFFER to point libcurl to a buffer of yours -where it'll store a human readable error message as well. - -If you then want to transfer another file, the handle is ready to be used -again. Mind you, it is even preferred that you re-use an existing handle if -you intend to make another transfer. libcurl will then attempt to re-use the -previous connection. - -For some protocols, downloading a file can involve a complicated process of -logging in, setting the transfer mode, changing the current directory and -finally transferring the file data. libcurl takes care of all that -complication for you. Given simply the URL to a file, libcurl will take care -of all the details needed to get the file moved from one machine to another. - -.SH "Multi-threading Issues" -The first basic rule is that you must \fBnever\fP simultaneously share a -libcurl handle (be it easy or multi or whatever) between multiple -threads. Only use one handle in one thread at any time. You can pass the -handles around among threads, but you must never use a single handle from more -than one thread at any given time. - -libcurl is completely thread safe, except for two issues: signals and SSL/TLS -handlers. Signals are used for timing out name resolves (during DNS lookup) - -when built without c-ares support and not on Windows. - -If you are accessing HTTPS or FTPS URLs in a multi-threaded manner, you are -then of course using the underlying SSL library multi-threaded and those libs -might have their own requirements on this issue. Basically, you need to -provide one or two functions to allow it to function properly. For all -details, see this: - -OpenSSL - - http://www.openssl.org/docs/crypto/threads.html#DESCRIPTION - -GnuTLS - - http://www.gnu.org/software/gnutls/manual/html_node/Multi_002dthreaded-applications.html - -NSS - - is claimed to be thread-safe already without anything required. - -PolarSSL - - Required actions unknown. - -yassl - - Required actions unknown. - -axTLS - - Required actions unknown. - -When using multiple threads you should set the CURLOPT_NOSIGNAL option to 1 -for all handles. Everything will or might work fine except that timeouts are -not honored during the DNS lookup - which you can work around by building -libcurl with c-ares support. c-ares is a library that provides asynchronous -name resolves. On some platforms, libcurl simply will not function properly -multi-threaded unless this option is set. - -Also, note that CURLOPT_DNS_USE_GLOBAL_CACHE is not thread-safe. - -.SH "When It Doesn't Work" -There will always be times when the transfer fails for some reason. You might -have set the wrong libcurl option or misunderstood what the libcurl option -actually does, or the remote server might return non-standard replies that -confuse the library which then confuses your program. - -There's one golden rule when these things occur: set the CURLOPT_VERBOSE -option to 1. It'll cause the library to spew out the entire protocol -details it sends, some internal info and some received protocol data as well -(especially when using FTP). If you're using HTTP, adding the headers in the -received output to study is also a clever way to get a better understanding -why the server behaves the way it does. Include headers in the normal body -output with CURLOPT_HEADER set 1. - -Of course, there are bugs left. We need to know about them to be able -to fix them, so we're quite dependent on your bug reports! When you do report -suspected bugs in libcurl, please include as many details as you possibly can: a -protocol dump that CURLOPT_VERBOSE produces, library version, as much as -possible of your code that uses libcurl, operating system name and version, -compiler name and version etc. - -If CURLOPT_VERBOSE is not enough, you increase the level of debug data your -application receive by using the CURLOPT_DEBUGFUNCTION. - -Getting some in-depth knowledge about the protocols involved is never wrong, -and if you're trying to do funny things, you might very well understand -libcurl and how to use it better if you study the appropriate RFC documents -at least briefly. - -.SH "Upload Data to a Remote Site" -libcurl tries to keep a protocol independent approach to most transfers, thus -uploading to a remote FTP site is very similar to uploading data to a HTTP -server with a PUT request. - -Of course, first you either create an easy handle or you re-use one existing -one. Then you set the URL to operate on just like before. This is the remote -URL, that we now will upload. - -Since we write an application, we most likely want libcurl to get the upload -data by asking us for it. To make it do that, we set the read callback and -the custom pointer libcurl will pass to our read callback. The read callback -should have a prototype similar to: - - size_t function(char *bufptr, size_t size, size_t nitems, void *userp); - -Where bufptr is the pointer to a buffer we fill in with data to upload and -size*nitems is the size of the buffer and therefore also the maximum amount -of data we can return to libcurl in this call. The 'userp' pointer is the -custom pointer we set to point to a struct of ours to pass private data -between the application and the callback. - - curl_easy_setopt(easyhandle, CURLOPT_READFUNCTION, read_function); - - curl_easy_setopt(easyhandle, CURLOPT_READDATA, &filedata); - -Tell libcurl that we want to upload: - - curl_easy_setopt(easyhandle, CURLOPT_UPLOAD, 1L); - -A few protocols won't behave properly when uploads are done without any prior -knowledge of the expected file size. So, set the upload file size using the -CURLOPT_INFILESIZE_LARGE for all known file sizes like this[1]: - -.nf - /* in this example, file_size must be an curl_off_t variable */ - curl_easy_setopt(easyhandle, CURLOPT_INFILESIZE_LARGE, file_size); -.fi - -When you call \fIcurl_easy_perform(3)\fP this time, it'll perform all the -necessary operations and when it has invoked the upload it'll call your -supplied callback to get the data to upload. The program should return as much -data as possible in every invoke, as that is likely to make the upload perform -as fast as possible. The callback should return the number of bytes it wrote -in the buffer. Returning 0 will signal the end of the upload. - -.SH "Passwords" -Many protocols use or even require that user name and password are provided -to be able to download or upload the data of your choice. libcurl offers -several ways to specify them. - -Most protocols support that you specify the name and password in the URL -itself. libcurl will detect this and use them accordingly. This is written -like this: - - protocol://user:password@example.com/path/ - -If you need any odd letters in your user name or password, you should enter -them URL encoded, as %XX where XX is a two-digit hexadecimal number. - -libcurl also provides options to set various passwords. The user name and -password as shown embedded in the URL can instead get set with the -CURLOPT_USERPWD option. The argument passed to libcurl should be a char * to -a string in the format "user:password". In a manner like this: - - curl_easy_setopt(easyhandle, CURLOPT_USERPWD, "myname:thesecret"); - -Another case where name and password might be needed at times, is for those -users who need to authenticate themselves to a proxy they use. libcurl offers -another option for this, the CURLOPT_PROXYUSERPWD. It is used quite similar -to the CURLOPT_USERPWD option like this: - - curl_easy_setopt(easyhandle, CURLOPT_PROXYUSERPWD, "myname:thesecret"); - -There's a long time UNIX "standard" way of storing ftp user names and -passwords, namely in the $HOME/.netrc file. The file should be made private -so that only the user may read it (see also the "Security Considerations" -chapter), as it might contain the password in plain text. libcurl has the -ability to use this file to figure out what set of user name and password to -use for a particular host. As an extension to the normal functionality, -libcurl also supports this file for non-FTP protocols such as HTTP. To make -curl use this file, use the CURLOPT_NETRC option: - - curl_easy_setopt(easyhandle, CURLOPT_NETRC, 1L); - -And a very basic example of how such a .netrc file may look like: - -.nf - machine myhost.mydomain.com - login userlogin - password secretword -.fi - -All these examples have been cases where the password has been optional, or -at least you could leave it out and have libcurl attempt to do its job -without it. There are times when the password isn't optional, like when -you're using an SSL private key for secure transfers. - -To pass the known private key password to libcurl: - - curl_easy_setopt(easyhandle, CURLOPT_KEYPASSWD, "keypassword"); - -.SH "HTTP Authentication" -The previous chapter showed how to set user name and password for getting -URLs that require authentication. When using the HTTP protocol, there are -many different ways a client can provide those credentials to the server and -you can control which way libcurl will (attempt to) use them. The default HTTP -authentication method is called 'Basic', which is sending the name and -password in clear-text in the HTTP request, base64-encoded. This is insecure. - -At the time of this writing, libcurl can be built to use: Basic, Digest, NTLM, -Negotiate, GSS-Negotiate and SPNEGO. You can tell libcurl which one to use -with CURLOPT_HTTPAUTH as in: - - curl_easy_setopt(easyhandle, CURLOPT_HTTPAUTH, CURLAUTH_DIGEST); - -And when you send authentication to a proxy, you can also set authentication -type the same way but instead with CURLOPT_PROXYAUTH: - - curl_easy_setopt(easyhandle, CURLOPT_PROXYAUTH, CURLAUTH_NTLM); - -Both these options allow you to set multiple types (by ORing them together), -to make libcurl pick the most secure one out of the types the server/proxy -claims to support. This method does however add a round-trip since libcurl -must first ask the server what it supports: - - curl_easy_setopt(easyhandle, CURLOPT_HTTPAUTH, - CURLAUTH_DIGEST|CURLAUTH_BASIC); - -For convenience, you can use the 'CURLAUTH_ANY' define (instead of a list -with specific types) which allows libcurl to use whatever method it wants. - -When asking for multiple types, libcurl will pick the available one it -considers "best" in its own internal order of preference. - -.SH "HTTP POSTing" -We get many questions regarding how to issue HTTP POSTs with libcurl the -proper way. This chapter will thus include examples using both different -versions of HTTP POST that libcurl supports. - -The first version is the simple POST, the most common version, that most HTML -pages using the <form> tag uses. We provide a pointer to the data and tell -libcurl to post it all to the remote site: - -.nf - char *data="name=daniel&project=curl"; - curl_easy_setopt(easyhandle, CURLOPT_POSTFIELDS, data); - curl_easy_setopt(easyhandle, CURLOPT_URL, "http://posthere.com/"); - - curl_easy_perform(easyhandle); /* post away! */ -.fi - -Simple enough, huh? Since you set the POST options with the -CURLOPT_POSTFIELDS, this automatically switches the handle to use POST in the -upcoming request. - -Ok, so what if you want to post binary data that also requires you to set the -Content-Type: header of the post? Well, binary posts prevent libcurl from -being able to do strlen() on the data to figure out the size, so therefore we -must tell libcurl the size of the post data. Setting headers in libcurl -requests are done in a generic way, by building a list of our own headers and -then passing that list to libcurl. - -.nf - struct curl_slist *headers=NULL; - headers = curl_slist_append(headers, "Content-Type: text/xml"); - - /* post binary data */ - curl_easy_setopt(easyhandle, CURLOPT_POSTFIELDS, binaryptr); - - /* set the size of the postfields data */ - curl_easy_setopt(easyhandle, CURLOPT_POSTFIELDSIZE, 23L); - - /* pass our list of custom made headers */ - curl_easy_setopt(easyhandle, CURLOPT_HTTPHEADER, headers); - - curl_easy_perform(easyhandle); /* post away! */ - - curl_slist_free_all(headers); /* free the header list */ -.fi - -While the simple examples above cover the majority of all cases where HTTP -POST operations are required, they don't do multi-part formposts. Multi-part -formposts were introduced as a better way to post (possibly large) binary data -and were first documented in the RFC1867 (updated in RFC2388). They're called -multi-part because they're built by a chain of parts, each part being a single -unit of data. Each part has its own name and contents. You can in fact create -and post a multi-part formpost with the regular libcurl POST support described -above, but that would require that you build a formpost yourself and provide -to libcurl. To make that easier, libcurl provides \fIcurl_formadd(3)\fP. Using -this function, you add parts to the form. When you're done adding parts, you -post the whole form. - -The following example sets two simple text parts with plain textual contents, -and then a file with binary contents and uploads the whole thing. - -.nf - struct curl_httppost *post=NULL; - struct curl_httppost *last=NULL; - curl_formadd(&post, &last, - CURLFORM_COPYNAME, "name", - CURLFORM_COPYCONTENTS, "daniel", CURLFORM_END); - curl_formadd(&post, &last, - CURLFORM_COPYNAME, "project", - CURLFORM_COPYCONTENTS, "curl", CURLFORM_END); - curl_formadd(&post, &last, - CURLFORM_COPYNAME, "logotype-image", - CURLFORM_FILECONTENT, "curl.png", CURLFORM_END); - - /* Set the form info */ - curl_easy_setopt(easyhandle, CURLOPT_HTTPPOST, post); - - curl_easy_perform(easyhandle); /* post away! */ - - /* free the post data again */ - curl_formfree(post); -.fi - -Multipart formposts are chains of parts using MIME-style separators and -headers. It means that each one of these separate parts get a few headers set -that describe the individual content-type, size etc. To enable your -application to handicraft this formpost even more, libcurl allows you to -supply your own set of custom headers to such an individual form part. You can -of course supply headers to as many parts as you like, but this little example -will show how you set headers to one specific part when you add that to the -post handle: - -.nf - struct curl_slist *headers=NULL; - headers = curl_slist_append(headers, "Content-Type: text/xml"); - - curl_formadd(&post, &last, - CURLFORM_COPYNAME, "logotype-image", - CURLFORM_FILECONTENT, "curl.xml", - CURLFORM_CONTENTHEADER, headers, - CURLFORM_END); - - curl_easy_perform(easyhandle); /* post away! */ - - curl_formfree(post); /* free post */ - curl_slist_free_all(headers); /* free custom header list */ -.fi - -Since all options on an easyhandle are "sticky", they remain the same until -changed even if you do call \fIcurl_easy_perform(3)\fP, you may need to tell -curl to go back to a plain GET request if you intend to do one as your -next request. You force an easyhandle to go back to GET by using the -CURLOPT_HTTPGET option: - - curl_easy_setopt(easyhandle, CURLOPT_HTTPGET, 1L); - -Just setting CURLOPT_POSTFIELDS to "" or NULL will *not* stop libcurl from -doing a POST. It will just make it POST without any data to send! - -.SH "Showing Progress" - -For historical and traditional reasons, libcurl has a built-in progress meter -that can be switched on and then makes it present a progress meter in your -terminal. - -Switch on the progress meter by, oddly enough, setting CURLOPT_NOPROGRESS to -zero. This option is set to 1 by default. - -For most applications however, the built-in progress meter is useless and -what instead is interesting is the ability to specify a progress -callback. The function pointer you pass to libcurl will then be called on -irregular intervals with information about the current transfer. - -Set the progress callback by using CURLOPT_PROGRESSFUNCTION. And pass a -pointer to a function that matches this prototype: - -.nf - int progress_callback(void *clientp, - double dltotal, - double dlnow, - double ultotal, - double ulnow); -.fi - -If any of the input arguments is unknown, a 0 will be passed. The first -argument, the 'clientp' is the pointer you pass to libcurl with -CURLOPT_PROGRESSDATA. libcurl won't touch it. - -.SH "libcurl with C++" - -There's basically only one thing to keep in mind when using C++ instead of C -when interfacing libcurl: - -The callbacks CANNOT be non-static class member functions - -Example C++ code: - -.nf -class AClass { - static size_t write_data(void *ptr, size_t size, size_t nmemb, - void *ourpointer) - { - /* do what you want with the data */ - } - } -.fi - -.SH "Proxies" - -What "proxy" means according to Merriam-Webster: "a person authorized to act -for another" but also "the agency, function, or office of a deputy who acts as -a substitute for another". - -Proxies are exceedingly common these days. Companies often only offer Internet -access to employees through their proxies. Network clients or user-agents ask -the proxy for documents, the proxy does the actual request and then it returns -them. - -libcurl supports SOCKS and HTTP proxies. When a given URL is wanted, libcurl -will ask the proxy for it instead of trying to connect to the actual host -identified in the URL. - -If you're using a SOCKS proxy, you may find that libcurl doesn't quite support -all operations through it. - -For HTTP proxies: the fact that the proxy is a HTTP proxy puts certain -restrictions on what can actually happen. A requested URL that might not be a -HTTP URL will be still be passed to the HTTP proxy to deliver back to -libcurl. This happens transparently, and an application may not need to -know. I say "may", because at times it is very important to understand that -all operations over a HTTP proxy use the HTTP protocol. For example, you -can't invoke your own custom FTP commands or even proper FTP directory -listings. - -.IP "Proxy Options" - -To tell libcurl to use a proxy at a given port number: - - curl_easy_setopt(easyhandle, CURLOPT_PROXY, "proxy-host.com:8080"); - -Some proxies require user authentication before allowing a request, and you -pass that information similar to this: - - curl_easy_setopt(easyhandle, CURLOPT_PROXYUSERPWD, "user:password"); - -If you want to, you can specify the host name only in the CURLOPT_PROXY -option, and set the port number separately with CURLOPT_PROXYPORT. - -Tell libcurl what kind of proxy it is with CURLOPT_PROXYTYPE (if not, it will -default to assume a HTTP proxy): - - curl_easy_setopt(easyhandle, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS4); - -.IP "Environment Variables" - -libcurl automatically checks and uses a set of environment variables to know -what proxies to use for certain protocols. The names of the variables are -following an ancient de facto standard and are built up as "[protocol]_proxy" -(note the lower casing). Which makes the variable \&'http_proxy' checked for a -name of a proxy to use when the input URL is HTTP. Following the same rule, -the variable named 'ftp_proxy' is checked for FTP URLs. Again, the proxies are -always HTTP proxies, the different names of the variables simply allows -different HTTP proxies to be used. - -The proxy environment variable contents should be in the format -\&"[protocol://][user:password@]machine[:port]". Where the protocol:// part is -simply ignored if present (so http://proxy and bluerk://proxy will do the -same) and the optional port number specifies on which port the proxy operates -on the host. If not specified, the internal default port number will be used -and that is most likely *not* the one you would like it to be. - -There are two special environment variables. 'all_proxy' is what sets proxy -for any URL in case the protocol specific variable wasn't set, and -\&'no_proxy' defines a list of hosts that should not use a proxy even though a -variable may say so. If 'no_proxy' is a plain asterisk ("*") it matches all -hosts. - -To explicitly disable libcurl's checking for and using the proxy environment -variables, set the proxy name to "" - an empty string - with CURLOPT_PROXY. -.IP "SSL and Proxies" - -SSL is for secure point-to-point connections. This involves strong encryption -and similar things, which effectively makes it impossible for a proxy to -operate as a "man in between" which the proxy's task is, as previously -discussed. Instead, the only way to have SSL work over a HTTP proxy is to ask -the proxy to tunnel trough everything without being able to check or fiddle -with the traffic. - -Opening an SSL connection over a HTTP proxy is therefor a matter of asking the -proxy for a straight connection to the target host on a specified port. This -is made with the HTTP request CONNECT. ("please mr proxy, connect me to that -remote host"). - -Because of the nature of this operation, where the proxy has no idea what kind -of data that is passed in and out through this tunnel, this breaks some of the -very few advantages that come from using a proxy, such as caching. Many -organizations prevent this kind of tunneling to other destination port numbers -than 443 (which is the default HTTPS port number). - -.IP "Tunneling Through Proxy" -As explained above, tunneling is required for SSL to work and often even -restricted to the operation intended for SSL; HTTPS. - -This is however not the only time proxy-tunneling might offer benefits to -you or your application. - -As tunneling opens a direct connection from your application to the remote -machine, it suddenly also re-introduces the ability to do non-HTTP -operations over a HTTP proxy. You can in fact use things such as FTP -upload or FTP custom commands this way. - -Again, this is often prevented by the administrators of proxies and is -rarely allowed. - -Tell libcurl to use proxy tunneling like this: - - curl_easy_setopt(easyhandle, CURLOPT_HTTPPROXYTUNNEL, 1L); - -In fact, there might even be times when you want to do plain HTTP -operations using a tunnel like this, as it then enables you to operate on -the remote server instead of asking the proxy to do so. libcurl will not -stand in the way for such innovative actions either! - -.IP "Proxy Auto-Config" - -Netscape first came up with this. It is basically a web page (usually using a -\&.pac extension) with a Javascript that when executed by the browser with the -requested URL as input, returns information to the browser on how to connect -to the URL. The returned information might be "DIRECT" (which means no proxy -should be used), "PROXY host:port" (to tell the browser where the proxy for -this particular URL is) or "SOCKS host:port" (to direct the browser to a SOCKS -proxy). - -libcurl has no means to interpret or evaluate Javascript and thus it doesn't -support this. If you get yourself in a position where you face this nasty -invention, the following advice have been mentioned and used in the past: - -- Depending on the Javascript complexity, write up a script that translates it -to another language and execute that. - -- Read the Javascript code and rewrite the same logic in another language. - -- Implement a Javascript interpreter; people have successfully used the -Mozilla Javascript engine in the past. - -- Ask your admins to stop this, for a static proxy setup or similar. - -.SH "Persistence Is The Way to Happiness" - -Re-cycling the same easy handle several times when doing multiple requests is -the way to go. - -After each single \fIcurl_easy_perform(3)\fP operation, libcurl will keep the -connection alive and open. A subsequent request using the same easy handle to -the same host might just be able to use the already open connection! This -reduces network impact a lot. - -Even if the connection is dropped, all connections involving SSL to the same -host again, will benefit from libcurl's session ID cache that drastically -reduces re-connection time. - -FTP connections that are kept alive save a lot of time, as the command- -response round-trips are skipped, and also you don't risk getting blocked -without permission to login again like on many FTP servers only allowing N -persons to be logged in at the same time. - -libcurl caches DNS name resolving results, to make lookups of a previously -looked up name a lot faster. - -Other interesting details that improve performance for subsequent requests -may also be added in the future. - -Each easy handle will attempt to keep the last few connections alive for a -while in case they are to be used again. You can set the size of this "cache" -with the CURLOPT_MAXCONNECTS option. Default is 5. There is very seldom any -point in changing this value, and if you think of changing this it is often -just a matter of thinking again. - -To force your upcoming request to not use an already existing connection (it -will even close one first if there happens to be one alive to the same host -you're about to operate on), you can do that by setting CURLOPT_FRESH_CONNECT -to 1. In a similar spirit, you can also forbid the upcoming request to be -"lying" around and possibly get re-used after the request by setting -CURLOPT_FORBID_REUSE to 1. - -.SH "HTTP Headers Used by libcurl" -When you use libcurl to do HTTP requests, it'll pass along a series of headers -automatically. It might be good for you to know and understand these. You -can replace or remove them by using the CURLOPT_HTTPHEADER option. - -.IP "Host" -This header is required by HTTP 1.1 and even many 1.0 servers and should be -the name of the server we want to talk to. This includes the port number if -anything but default. - -.IP "Accept" -\&"*/*". - -.IP "Expect" -When doing POST requests, libcurl sets this header to \&"100-continue" to ask -the server for an "OK" message before it proceeds with sending the data part -of the post. If the POSTed data amount is deemed "small", libcurl will not use -this header. - -.SH "Customizing Operations" -There is an ongoing development today where more and more protocols are built -upon HTTP for transport. This has obvious benefits as HTTP is a tested and -reliable protocol that is widely deployed and has excellent proxy-support. - -When you use one of these protocols, and even when doing other kinds of -programming you may need to change the traditional HTTP (or FTP or...) -manners. You may need to change words, headers or various data. - -libcurl is your friend here too. - -.IP CUSTOMREQUEST -If just changing the actual HTTP request keyword is what you want, like when -GET, HEAD or POST is not good enough for you, CURLOPT_CUSTOMREQUEST is there -for you. It is very simple to use: - - curl_easy_setopt(easyhandle, CURLOPT_CUSTOMREQUEST, "MYOWNREQUEST"); - -When using the custom request, you change the request keyword of the actual -request you are performing. Thus, by default you make a GET request but you can -also make a POST operation (as described before) and then replace the POST -keyword if you want to. You're the boss. - -.IP "Modify Headers" -HTTP-like protocols pass a series of headers to the server when doing the -request, and you're free to pass any amount of extra headers that you -think fit. Adding headers is this easy: - -.nf - struct curl_slist *headers=NULL; /* init to NULL is important */ - - headers = curl_slist_append(headers, "Hey-server-hey: how are you?"); - headers = curl_slist_append(headers, "X-silly-content: yes"); - - /* pass our list of custom made headers */ - curl_easy_setopt(easyhandle, CURLOPT_HTTPHEADER, headers); - - curl_easy_perform(easyhandle); /* transfer http */ - - curl_slist_free_all(headers); /* free the header list */ -.fi - -\&... and if you think some of the internally generated headers, such as -Accept: or Host: don't contain the data you want them to contain, you can -replace them by simply setting them too: - -.nf - headers = curl_slist_append(headers, "Accept: Agent-007"); - headers = curl_slist_append(headers, "Host: munged.host.line"); -.fi - -.IP "Delete Headers" -If you replace an existing header with one with no contents, you will prevent -the header from being sent. For instance, if you want to completely prevent the -\&"Accept:" header from being sent, you can disable it with code similar to this: - - headers = curl_slist_append(headers, "Accept:"); - -Both replacing and canceling internal headers should be done with careful -consideration and you should be aware that you may violate the HTTP protocol -when doing so. - -.IP "Enforcing chunked transfer-encoding" - -By making sure a request uses the custom header "Transfer-Encoding: chunked" -when doing a non-GET HTTP operation, libcurl will switch over to "chunked" -upload, even though the size of the data to upload might be known. By default, -libcurl usually switches over to chunked upload automatically if the upload -data size is unknown. - -.IP "HTTP Version" - -All HTTP requests includes the version number to tell the server which version -we support. libcurl speaks HTTP 1.1 by default. Some very old servers don't -like getting 1.1-requests and when dealing with stubborn old things like that, -you can tell libcurl to use 1.0 instead by doing something like this: - - curl_easy_setopt(easyhandle, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0); - -.IP "FTP Custom Commands" - -Not all protocols are HTTP-like, and thus the above may not help you when -you want to make, for example, your FTP transfers to behave differently. - -Sending custom commands to a FTP server means that you need to send the -commands exactly as the FTP server expects them (RFC959 is a good guide -here), and you can only use commands that work on the control-connection -alone. All kinds of commands that require data interchange and thus need -a data-connection must be left to libcurl's own judgement. Also be aware -that libcurl will do its very best to change directory to the target -directory before doing any transfer, so if you change directory (with CWD -or similar) you might confuse libcurl and then it might not attempt to -transfer the file in the correct remote directory. - -A little example that deletes a given file before an operation: - -.nf - headers = curl_slist_append(headers, "DELE file-to-remove"); - - /* pass the list of custom commands to the handle */ - curl_easy_setopt(easyhandle, CURLOPT_QUOTE, headers); - - curl_easy_perform(easyhandle); /* transfer ftp data! */ - - curl_slist_free_all(headers); /* free the header list */ -.fi - -If you would instead want this operation (or chain of operations) to happen -_after_ the data transfer took place the option to \fIcurl_easy_setopt(3)\fP -would instead be called CURLOPT_POSTQUOTE and used the exact same way. - -The custom FTP command will be issued to the server in the same order they are -added to the list, and if a command gets an error code returned back from the -server, no more commands will be issued and libcurl will bail out with an -error code (CURLE_QUOTE_ERROR). Note that if you use CURLOPT_QUOTE to send -commands before a transfer, no transfer will actually take place when a quote -command has failed. - -If you set the CURLOPT_HEADER to 1, you will tell libcurl to get -information about the target file and output "headers" about it. The headers -will be in "HTTP-style", looking like they do in HTTP. - -The option to enable headers or to run custom FTP commands may be useful to -combine with CURLOPT_NOBODY. If this option is set, no actual file content -transfer will be performed. - -.IP "FTP Custom CUSTOMREQUEST" -If you do want to list the contents of a FTP directory using your own defined FTP -command, CURLOPT_CUSTOMREQUEST will do just that. "NLST" is the default one -for listing directories but you're free to pass in your idea of a good -alternative. - -.SH "Cookies Without Chocolate Chips" -In the HTTP sense, a cookie is a name with an associated value. A server sends -the name and value to the client, and expects it to get sent back on every -subsequent request to the server that matches the particular conditions -set. The conditions include that the domain name and path match and that the -cookie hasn't become too old. - -In real-world cases, servers send new cookies to replace existing ones to -update them. Server use cookies to "track" users and to keep "sessions". - -Cookies are sent from server to clients with the header Set-Cookie: and -they're sent from clients to servers with the Cookie: header. - -To just send whatever cookie you want to a server, you can use CURLOPT_COOKIE -to set a cookie string like this: - - curl_easy_setopt(easyhandle, CURLOPT_COOKIE, "name1=var1; name2=var2;"); - -In many cases, that is not enough. You might want to dynamically save -whatever cookies the remote server passes to you, and make sure those cookies -are then used accordingly on later requests. - -One way to do this, is to save all headers you receive in a plain file and -when you make a request, you tell libcurl to read the previous headers to -figure out which cookies to use. Set the header file to read cookies from with -CURLOPT_COOKIEFILE. - -The CURLOPT_COOKIEFILE option also automatically enables the cookie parser in -libcurl. Until the cookie parser is enabled, libcurl will not parse or -understand incoming cookies and they will just be ignored. However, when the -parser is enabled the cookies will be understood and the cookies will be kept -in memory and used properly in subsequent requests when the same handle is -used. Many times this is enough, and you may not have to save the cookies to -disk at all. Note that the file you specify to CURLOPT_COOKIEFILE doesn't have -to exist to enable the parser, so a common way to just enable the parser and -not read any cookies is to use the name of a file you know doesn't exist. - -If you would rather use existing cookies that you've previously received with -your Netscape or Mozilla browsers, you can make libcurl use that cookie file -as input. The CURLOPT_COOKIEFILE is used for that too, as libcurl will -automatically find out what kind of file it is and act accordingly. - -Perhaps the most advanced cookie operation libcurl offers, is saving the -entire internal cookie state back into a Netscape/Mozilla formatted cookie -file. We call that the cookie-jar. When you set a file name with -CURLOPT_COOKIEJAR, that file name will be created and all received cookies -will be stored in it when \fIcurl_easy_cleanup(3)\fP is called. This enables -cookies to get passed on properly between multiple handles without any -information getting lost. - -.SH "FTP Peculiarities We Need" - -FTP transfers use a second TCP/IP connection for the data transfer. This is -usually a fact you can forget and ignore but at times this fact will come -back to haunt you. libcurl offers several different ways to customize how the -second connection is being made. - -libcurl can either connect to the server a second time or tell the server to -connect back to it. The first option is the default and it is also what works -best for all the people behind firewalls, NATs or IP-masquerading setups. -libcurl then tells the server to open up a new port and wait for a second -connection. This is by default attempted with EPSV first, and if that doesn't -work it tries PASV instead. (EPSV is an extension to the original FTP spec -and does not exist nor work on all FTP servers.) - -You can prevent libcurl from first trying the EPSV command by setting -CURLOPT_FTP_USE_EPSV to zero. - -In some cases, you will prefer to have the server connect back to you for the -second connection. This might be when the server is perhaps behind a firewall -or something and only allows connections on a single port. libcurl then -informs the remote server which IP address and port number to connect to. -This is made with the CURLOPT_FTPPORT option. If you set it to "-", libcurl -will use your system's "default IP address". If you want to use a particular -IP, you can set the full IP address, a host name to resolve to an IP address -or even a local network interface name that libcurl will get the IP address -from. - -When doing the "PORT" approach, libcurl will attempt to use the EPRT and the -LPRT before trying PORT, as they work with more protocols. You can disable -this behavior by setting CURLOPT_FTP_USE_EPRT to zero. - -.SH "Headers Equal Fun" - -Some protocols provide "headers", meta-data separated from the normal -data. These headers are by default not included in the normal data stream, -but you can make them appear in the data stream by setting CURLOPT_HEADER to -1. - -What might be even more useful, is libcurl's ability to separate the headers -from the data and thus make the callbacks differ. You can for example set a -different pointer to pass to the ordinary write callback by setting -CURLOPT_WRITEHEADER. - -Or, you can set an entirely separate function to receive the headers, by -using CURLOPT_HEADERFUNCTION. - -The headers are passed to the callback function one by one, and you can -depend on that fact. It makes it easier for you to add custom header parsers -etc. - -\&"Headers" for FTP transfers equal all the FTP server responses. They aren't -actually true headers, but in this case we pretend they are! ;-) - -.SH "Post Transfer Information" - - [ curl_easy_getinfo ] - -.SH "Security Considerations" - -The libcurl project takes security seriously. The library is written with -caution and precautions are taken to mitigate many kinds of risks encountered -while operating with potentially malicious servers on the Internet. It is a -powerful library, however, which allows application writers to make trade offs -between ease of writing and exposure to potential risky operations. If -used the right way, you can use libcurl to transfer data pretty safely. - -Many applications are used in closed networks where users and servers -can be trusted, but many others are used on arbitrary servers and are fed -input from potentially untrusted users. Following is a discussion about -some risks in the ways in which applications commonly use libcurl and -potential mitigations of those risks. It is by no means comprehensive, but -shows classes of attacks that robust applications should consider. The -Common Weakness Enumeration project at http://cwe.mitre.org/ is a good -reference for many of these and similar types of weaknesses of which -application writers should be aware. - -.IP "Command Lines" -If you use a command line tool (such as curl) that uses libcurl, and you give -options to the tool on the command line those options can very likely get read -by other users of your system when they use 'ps' or other tools to list -currently running processes. - -To avoid this problem, never feed sensitive things to programs using command -line options. Write them to a protected file and use the \-K option to -avoid this. - -.IP ".netrc" -\&.netrc is a pretty handy file/feature that allows you to login quickly and -automatically to frequently visited sites. The file contains passwords in -clear text and is a real security risk. In some cases, your .netrc is also -stored in a home directory that is NFS mounted or used on another network -based file system, so the clear text password will fly through your network -every time anyone reads that file! - -To avoid this problem, don't use .netrc files and never store passwords in -plain text anywhere. - -.IP "Clear Text Passwords" -Many of the protocols libcurl supports send name and password unencrypted as -clear text (HTTP Basic authentication, FTP, TELNET etc). It is very easy for -anyone on your network or a network nearby yours to just fire up a network -analyzer tool and eavesdrop on your passwords. Don't let the fact that HTTP -Basic uses base64 encoded passwords fool you. They may not look readable at a -first glance, but they very easily "deciphered" by anyone within seconds. - -To avoid this problem, use HTTP authentication methods or other protocols that -don't let snoopers see your password: HTTP with Digest, NTLM or GSS -authentication, HTTPS, FTPS, SCP, SFTP and FTP-Kerberos are a few examples. - -.IP "Redirects" -The CURLOPT_FOLLOWLOCATION option automatically follows HTTP redirects sent -by a remote server. These redirects can refer to any kind of URL, not just -HTTP. A redirect to a file: URL would cause the libcurl to read (or write) -arbitrary files from the local filesystem. If the application returns -the data back to the user (as would happen in some kinds of CGI scripts), -an attacker could leverage this to read otherwise forbidden data (e.g. -file://localhost/etc/passwd). - -If authentication credentials are stored in the ~/.netrc file, or Kerberos -is in use, any other URL type (not just file:) that requires -authentication is also at risk. A redirect such as -ftp://some-internal-server/private-file would then return data even when -the server is password protected. - -In the same way, if an unencrypted SSH private key has been configured for -the user running the libcurl application, SCP: or SFTP: URLs could access -password or private-key protected resources, -e.g. sftp://user@some-internal-server/etc/passwd - -The CURLOPT_REDIR_PROTOCOLS and CURLOPT_NETRC options can be used to -mitigate against this kind of attack. - -A redirect can also specify a location available only on the machine running -libcurl, including servers hidden behind a firewall from the attacker. -e.g. http://127.0.0.1/ or http://intranet/delete-stuff.cgi?delete=all or -tftp://bootp-server/pc-config-data - -Apps can mitigate against this by disabling CURLOPT_FOLLOWLOCATION and -handling redirects itself, sanitizing URLs as necessary. Alternately, an -app could leave CURLOPT_FOLLOWLOCATION enabled but set CURLOPT_REDIR_PROTOCOLS -and install a CURLOPT_OPENSOCKETFUNCTION callback function in which addresses -are sanitized before use. - -.IP "Private Resources" -A user who can control the DNS server of a domain being passed in within -a URL can change the address of the host to a local, private address -which the libcurl application will then use. e.g. The innocuous URL -http://fuzzybunnies.example.com/ could actually resolve to the IP address -of a server behind a firewall, such as 127.0.0.1 or 10.1.2.3 -Apps can mitigate against this by setting a CURLOPT_OPENSOCKETFUNCTION -and checking the address before a connection. - -All the malicious scenarios regarding redirected URLs apply just as well -to non-redirected URLs, if the user is allowed to specify an arbitrary URL -that could point to a private resource. For example, a web app providing -a translation service might happily translate file://localhost/etc/passwd -and display the result. Apps can mitigate against this with the -CURLOPT_PROTOCOLS option as well as by similar mitigation techniques for -redirections. - -A malicious FTP server could in response to the PASV command return an -IP address and port number for a server local to the app running libcurl -but behind a firewall. Apps can mitigate against this by using the -CURLOPT_FTP_SKIP_PASV_IP option or CURLOPT_FTPPORT. - -.IP Uploads -When uploading, a redirect can cause a local (or remote) file to be -overwritten. Apps must not allow any unsanitized URL to be passed in -for uploads. Also, CURLOPT_FOLLOWLOCATION should not be used on uploads. -Instead, the app should handle redirects itself, sanitizing each URL first. - -.IP Authentication -Use of CURLOPT_UNRESTRICTED_AUTH could cause authentication information to -be sent to an unknown second server. Apps can mitigate against this -by disabling CURLOPT_FOLLOWLOCATION and handling redirects itself, -sanitizing where necessary. - -Use of the CURLAUTH_ANY option to CURLOPT_HTTPAUTH could result in user -name and password being sent in clear text to an HTTP server. Instead, -use CURLAUTH_ANYSAFE which ensures that the password is encrypted over -the network, or else fail the request. - -Use of the CURLUSESSL_TRY option to CURLOPT_USE_SSL could result in user -name and password being sent in clear text to an FTP server. Instead, -use CURLUSESSL_CONTROL to ensure that an encrypted connection is used or -else fail the request. - -.IP Cookies -If cookies are enabled and cached, then a user could craft a URL which -performs some malicious action to a site whose authentication is already -stored in a cookie. e.g. http://mail.example.com/delete-stuff.cgi?delete=all -Apps can mitigate against this by disabling cookies or clearing them -between requests. - -.IP "Dangerous URLs" -SCP URLs can contain raw commands within the scp: URL, which is a side effect -of how the SCP protocol is designed. e.g. -scp://user:pass@host/a;date >/tmp/test; -Apps must not allow unsanitized SCP: URLs to be passed in for downloads. - -.IP "Denial of Service" -A malicious server could cause libcurl to effectively hang by sending -a trickle of data through, or even no data at all but just keeping the TCP -connection open. This could result in a denial-of-service attack. The -CURLOPT_TIMEOUT and/or CURLOPT_LOW_SPEED_LIMIT options can be used to -mitigate against this. - -A malicious server could cause libcurl to effectively hang by starting to -send data, then severing the connection without cleanly closing the -TCP connection. The app could install a CURLOPT_SOCKOPTFUNCTION callback -function and set the TCP SO_KEEPALIVE option to mitigate against this. -Setting one of the timeout options would also work against this attack. - -A malicious server could cause libcurl to download an infinite amount of -data, potentially causing all of memory or disk to be filled. Setting -the CURLOPT_MAXFILESIZE_LARGE option is not sufficient to guard against this. -Instead, the app should monitor the amount of data received within the -write or progress callback and abort once the limit is reached. - -A malicious HTTP server could cause an infinite redirection loop, causing a -denial-of-service. This can be mitigated by using the CURLOPT_MAXREDIRS -option. - -.IP "Arbitrary Headers" -User-supplied data must be sanitized when used in options like -CURLOPT_USERAGENT, CURLOPT_HTTPHEADER, CURLOPT_POSTFIELDS and others that -are used to generate structured data. Characters like embedded carriage -returns or ampersands could allow the user to create additional headers or -fields that could cause malicious transactions. - -.IP "Server-supplied Names" -A server can supply data which the application may, in some cases, use as -a file name. The curl command-line tool does this with --remote-header-name, -using the Content-disposition: header to generate a file name. An application -could also use CURLINFO_EFFECTIVE_URL to generate a file name from a -server-supplied redirect URL. Special care must be taken to sanitize such -names to avoid the possibility of a malicious server supplying one like -"/etc/passwd", "\autoexec.bat" or even ".bashrc". - -.IP "Server Certificates" -A secure application should never use the CURLOPT_SSL_VERIFYPEER option to -disable certificate validation. There are numerous attacks that are enabled -by apps that fail to properly validate server TLS/SSL certificates, -thus enabling a malicious server to spoof a legitimate one. HTTPS without -validated certificates is potentially as insecure as a plain HTTP connection. - -.IP "Showing What You Do" -On a related issue, be aware that even in situations like when you have -problems with libcurl and ask someone for help, everything you reveal in order -to get best possible help might also impose certain security related -risks. Host names, user names, paths, operating system specifics, etc (not to -mention passwords of course) may in fact be used by intruders to gain -additional information of a potential target. - -To avoid this problem, you must of course use your common sense. Often, you -can just edit out the sensitive data or just search/replace your true -information with faked data. - -.SH "Multiple Transfers Using the multi Interface" - -The easy interface as described in detail in this document is a synchronous -interface that transfers one file at a time and doesn't return until it is -done. - -The multi interface, on the other hand, allows your program to transfer -multiple files in both directions at the same time, without forcing you -to use multiple threads. The name might make it seem that the multi -interface is for multi-threaded programs, but the truth is almost the -reverse. The multi interface can allow a single-threaded application -to perform the same kinds of multiple, simultaneous transfers that -multi-threaded programs can perform. It allows many of the benefits -of multi-threaded transfers without the complexity of managing and -synchronizing many threads. - -To use this interface, you are better off if you first understand the basics -of how to use the easy interface. The multi interface is simply a way to make -multiple transfers at the same time by adding up multiple easy handles into -a "multi stack". - -You create the easy handles you want and you set all the options just like you -have been told above, and then you create a multi handle with -\fIcurl_multi_init(3)\fP and add all those easy handles to that multi handle -with \fIcurl_multi_add_handle(3)\fP. - -When you've added the handles you have for the moment (you can still add new -ones at any time), you start the transfers by calling -\fIcurl_multi_perform(3)\fP. - -\fIcurl_multi_perform(3)\fP is asynchronous. It will only execute as little as -possible and then return back control to your program. It is designed to never -block. - -The best usage of this interface is when you do a select() on all possible -file descriptors or sockets to know when to call libcurl again. This also -makes it easy for you to wait and respond to actions on your own application's -sockets/handles. You figure out what to select() for by using -\fIcurl_multi_fdset(3)\fP, that fills in a set of fd_set variables for you -with the particular file descriptors libcurl uses for the moment. - -When you then call select(), it'll return when one of the file handles signal -action and you then call \fIcurl_multi_perform(3)\fP to allow libcurl to do -what it wants to do. Take note that libcurl does also feature some time-out -code so we advise you to never use very long timeouts on select() before you -call \fIcurl_multi_perform(3)\fP, which thus should be called unconditionally -every now and then even if none of its file descriptors have signaled -ready.

That would probably be you or someone in your position. What will be generally referred to as 'the program' will be the collected source code that you write that is using libcurl for transfers. The program is outside libcurl and libcurl is outside of the program. -<p class="level0">To get more details on all options and functions described herein, please refer to their respective man pages. -<p class="level0"><a name="Building"></a><h2 class="nroffsh">Building</h2> -<p class="level0">There are many different ways to build C programs. This chapter will assume a UNIX-style build process. If you use a different build system, you can still read this to get general information that may apply to your environment as well. -<p class="level0"><a name="Compiling"></a><span class="nroffip">Compiling the Program</span> -<p class="level1">Your compiler needs to know where the libcurl headers are located. Therefore you must set your compiler's include path to point to the directory where you installed them. The 'curl-config'[3] tool can be used to get this information: -<p class="level1">$ curl-config --cflags -<p class="level1"> -<p class="level0"><a name="Linking"></a><span class="nroffip">Linking the Program with libcurl</span> -<p class="level1">When having compiled the program, you need to link your object files to create a single executable. For that to succeed, you need to link with libcurl and possibly also with other libraries that libcurl itself depends on. Like the OpenSSL libraries, but even some standard OS libraries may be needed on the command line. To figure out which flags to use, once again the 'curl-config' tool comes to the rescue: -<p class="level1">$ curl-config --libs -<p class="level1"> -<p class="level0"><a name="SSL"></a><span class="nroffip">SSL or Not</span> -<p class="level1">libcurl can be built and customized in many ways. One of the things that varies from different libraries and builds is the support for SSL-based transfers, like HTTPS and FTPS. If a supported SSL library was detected properly at build-time, libcurl will be built with SSL support. To figure out if an installed libcurl has been built with SSL support enabled, use 'curl-config' like this: -<p class="level1">$ curl-config --feature -<p class="level1">And if SSL is supported, the keyword 'SSL' will be written to stdout, possibly together with a few other features that could be either on or off on for different libcurls. -<p class="level1">See also the "Features libcurl Provides" further down. -<p class="level0"><a name="autoconf"></a><span class="nroffip">autoconf macro</span> -<p class="level1">When you write your configure script to detect libcurl and setup variables accordingly, we offer a prewritten macro that probably does everything you need in this area. See docs/libcurl/libcurl.m4 file - it includes docs on how to use it. -<p class="level1"><a name="Portable"></a><h2 class="nroffsh">Portable Code in a Portable World</h2> -<p class="level0">The people behind libcurl have put a considerable effort to make libcurl work on a large amount of different operating systems and environments. -<p class="level0">You program libcurl the same way on all platforms that libcurl runs on. There are only very few minor considerations that differ. If you just make sure to write your code portable enough, you may very well create yourself a very portable program. libcurl shouldn't stop you from that. -<p class="level0"><a name="Global"></a><h2 class="nroffsh">Global Preparation</h2> -<p class="level0">The program must initialize some of the libcurl functionality globally. That means it should be done exactly once, no matter how many times you intend to use the library. Once for your program's entire life time. This is done using -<p class="level0"> curl_global_init() -<p class="level0">and it takes one parameter which is a bit pattern that tells libcurl what to initialize. Using <span Class="emphasis">CURL_GLOBAL_ALL</span> will make it initialize all known internal sub modules, and might be a good default option. The current two bits that are specified are: -<p class="level1"> -<p class="level0"><a name="CURLGLOBALWIN32"></a><span class="nroffip">CURL_GLOBAL_WIN32</span> -<p class="level1">which only does anything on Windows machines. When used on a Windows machine, it'll make libcurl initialize the win32 socket stuff. Without having that initialized properly, your program cannot use sockets properly. You should only do this once for each application, so if your program already does this or of another library in use does it, you should not tell libcurl to do this as well. -<p class="level0"><a name="CURLGLOBALSSL"></a><span class="nroffip">CURL_GLOBAL_SSL</span> -<p class="level1">which only does anything on libcurls compiled and built SSL-enabled. On these systems, this will make libcurl initialize the SSL library properly for this application. This only needs to be done once for each application so if your program or another library already does this, this bit should not be needed. -<p class="level0"> -<p class="level0">libcurl has a default protection mechanism that detects if <a class="emphasis" href="./curl_global_init.html">curl_global_init(3)</a> hasn't been called by the time <a class="emphasis" href="./curl_easy_perform.html">curl_easy_perform(3)</a> is called and if that is the case, libcurl runs the function itself with a guessed bit pattern. Please note that depending solely on this is not considered nice nor very good. -<p class="level0">When the program no longer uses libcurl, it should call <a class="emphasis" href="./curl_global_cleanup.html">curl_global_cleanup(3)</a>, which is the opposite of the init call. It will then do the reversed operations to cleanup the resources the <a class="emphasis" href="./curl_global_init.html">curl_global_init(3)</a> call initialized. -<p class="level0">Repeated calls to <a class="emphasis" href="./curl_global_init.html">curl_global_init(3)</a> and <a class="emphasis" href="./curl_global_cleanup.html">curl_global_cleanup(3)</a> should be avoided. They should only be called once each. -<p class="level0"><a name="Features"></a><h2 class="nroffsh">Features libcurl Provides</h2> -<p class="level0">It is considered best-practice to determine libcurl features at run-time rather than at build-time (if possible of course). By calling <a class="emphasis" href="./curl_version_info.html">curl_version_info(3)</a> and checking out the details of the returned struct, your program can figure out exactly what the currently running libcurl supports. -<p class="level0"><a name="Handle"></a><h2 class="nroffsh">Handle the Easy libcurl</h2> -<p class="level0">libcurl first introduced the so called easy interface. All operations in the easy interface are prefixed with 'curl_easy'. -<p class="level0">Recent libcurl versions also offer the multi interface. More about that interface, what it is targeted for and how to use it is detailed in a separate chapter further down. You still need to understand the easy interface first, so please continue reading for better understanding. -<p class="level0">To use the easy interface, you must first create yourself an easy handle. You need one handle for each easy session you want to perform. Basically, you should use one handle for every thread you plan to use for transferring. You must never share the same handle in multiple threads. -<p class="level0">Get an easy handle with -<p class="level0"> easyhandle = curl_easy_init(); -<p class="level0">It returns an easy handle. Using that you proceed to the next step: setting up your preferred actions. A handle is just a logic entity for the upcoming transfer or series of transfers. -<p class="level0">You set properties and options for this handle using <a class="emphasis" href="./curl_easy_setopt.html">curl_easy_setopt(3)</a>. They control how the subsequent transfer or transfers will be made. Options remain set in the handle until set again to something different. Alas, multiple requests using the same handle will use the same options. -<p class="level0">Many of the options you set in libcurl are "strings", pointers to data terminated with a zero byte. When you set strings with <a class="emphasis" href="./curl_easy_setopt.html">curl_easy_setopt(3)</a>, libcurl makes its own copy so that they don't need to be kept around in your application after being set[4]. -<p class="level0">One of the most basic properties to set in the handle is the URL. You set your preferred URL to transfer with CURLOPT_URL in a manner similar to: -<p class="level0"> -<p class="level0"> curl_easy_setopt(handle, CURLOPT_URL, "<a href="http://domain.com/">http://domain.com/</a>"); -<p class="level0"> -<p class="level0">Let's assume for a while that you want to receive data as the URL identifies a remote resource you want to get here. Since you write a sort of application that needs this transfer, I assume that you would like to get the data passed to you directly instead of simply getting it passed to stdout. So, you write your own function that matches this prototype: -<p class="level0"> size_t write_data(void *buffer, size_t size, size_t nmemb, void *userp); -<p class="level0">You tell libcurl to pass all data to this function by issuing a function similar to this: -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_WRITEFUNCTION, write_data); -<p class="level0">You can control what data your callback function gets in the fourth argument by setting another property: -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_WRITEDATA, &internal_struct); -<p class="level0">Using that property, you can easily pass local data between your application and the function that gets invoked by libcurl. libcurl itself won't touch the data you pass with <span Class="emphasis">CURLOPT_WRITEDATA</span>. -<p class="level0">libcurl offers its own default internal callback that will take care of the data if you don't set the callback with <span Class="emphasis">CURLOPT_WRITEFUNCTION</span>. It will then simply output the received data to stdout. You can have the default callback write the data to a different file handle by passing a 'FILE *' to a file opened for writing with the <span Class="emphasis">CURLOPT_WRITEDATA</span> option. -<p class="level0">Now, we need to take a step back and have a deep breath. Here's one of those rare platform-dependent nitpicks. Did you spot it? On some platforms[2], libcurl won't be able to operate on files opened by the program. Thus, if you use the default callback and pass in an open file with <span Class="emphasis">CURLOPT_WRITEDATA</span>, it will crash. You should therefore avoid this to make your program run fine virtually everywhere. -<p class="level0">(<span Class="emphasis">CURLOPT_WRITEDATA</span> was formerly known as <span Class="emphasis">CURLOPT_FILE</span>. Both names still work and do the same thing). -<p class="level0">If you're using libcurl as a win32 DLL, you MUST use the <span Class="emphasis">CURLOPT_WRITEFUNCTION</span> if you set <span Class="emphasis">CURLOPT_WRITEDATA</span> - or you will experience crashes. -<p class="level0">There are of course many more options you can set, and we'll get back to a few of them later. Let's instead continue to the actual transfer: -<p class="level0"> success = curl_easy_perform(easyhandle); -<p class="level0"><a class="emphasis" href="./curl_easy_perform.html">curl_easy_perform(3)</a> will connect to the remote site, do the necessary commands and receive the transfer. Whenever it receives data, it calls the callback function we previously set. The function may get one byte at a time, or it may get many kilobytes at once. libcurl delivers as much as possible as often as possible. Your callback function should return the number of bytes it "took care of". If that is not the exact same amount of bytes that was passed to it, libcurl will abort the operation and return with an error code. -<p class="level0">When the transfer is complete, the function returns a return code that informs you if it succeeded in its mission or not. If a return code isn't enough for you, you can use the CURLOPT_ERRORBUFFER to point libcurl to a buffer of yours where it'll store a human readable error message as well. -<p class="level0">If you then want to transfer another file, the handle is ready to be used again. Mind you, it is even preferred that you re-use an existing handle if you intend to make another transfer. libcurl will then attempt to re-use the previous connection. -<p class="level0">For some protocols, downloading a file can involve a complicated process of logging in, setting the transfer mode, changing the current directory and finally transferring the file data. libcurl takes care of all that complication for you. Given simply the URL to a file, libcurl will take care of all the details needed to get the file moved from one machine to another. -<p class="level0"><a name="Multi-threading"></a><h2 class="nroffsh">Multi-threading Issues</h2> -<p class="level0">The first basic rule is that you must <span Class="bold">never</span> simultaneously share a libcurl handle (be it easy or multi or whatever) between multiple threads. Only use one handle in one thread at any time. You can pass the handles around among threads, but you must never use a single handle from more than one thread at any given time. -<p class="level0">libcurl is completely thread safe, except for two issues: signals and SSL/TLS handlers. Signals are used for timing out name resolves (during DNS lookup) - when built without c-ares support and not on Windows. -<p class="level0">If you are accessing HTTPS or FTPS URLs in a multi-threaded manner, you are then of course using the underlying SSL library multi-threaded and those libs might have their own requirements on this issue. Basically, you need to provide one or two functions to allow it to function properly. For all details, see this: -<p class="level0">OpenSSL -<p class="level0"> <a href="http://www.openssl.org/docs/crypto/threads.html">http://www.openssl.org/docs/crypto/threads.html</a>#DESCRIPTION -<p class="level0">GnuTLS -<p class="level0"> <a href="http://www.gnu.org/software/gnutls/manual/html_node/">http://www.gnu.org/software/gnutls/manual/html_node/</a>Multi_002dthreaded-applications.html -<p class="level0">NSS -<p class="level0"> is claimed to be thread-safe already without anything required. -<p class="level0">PolarSSL -<p class="level0"> Required actions unknown. -<p class="level0">yassl -<p class="level0"> Required actions unknown. -<p class="level0">axTLS -<p class="level0"> Required actions unknown. -<p class="level0">When using multiple threads you should set the CURLOPT_NOSIGNAL option to 1 for all handles. Everything will or might work fine except that timeouts are not honored during the DNS lookup - which you can work around by building libcurl with c-ares support. c-ares is a library that provides asynchronous name resolves. On some platforms, libcurl simply will not function properly multi-threaded unless this option is set. -<p class="level0">Also, note that CURLOPT_DNS_USE_GLOBAL_CACHE is not thread-safe. -<p class="level0"><a name="When"></a><h2 class="nroffsh">When It Doesn't Work</h2> -<p class="level0">There will always be times when the transfer fails for some reason. You might have set the wrong libcurl option or misunderstood what the libcurl option actually does, or the remote server might return non-standard replies that confuse the library which then confuses your program. -<p class="level0">There's one golden rule when these things occur: set the CURLOPT_VERBOSE option to 1. It'll cause the library to spew out the entire protocol details it sends, some internal info and some received protocol data as well (especially when using FTP). If you're using HTTP, adding the headers in the received output to study is also a clever way to get a better understanding why the server behaves the way it does. Include headers in the normal body output with CURLOPT_HEADER set 1. -<p class="level0">Of course, there are bugs left. We need to know about them to be able to fix them, so we're quite dependent on your bug reports! When you do report suspected bugs in libcurl, please include as many details as you possibly can: a protocol dump that CURLOPT_VERBOSE produces, library version, as much as possible of your code that uses libcurl, operating system name and version, compiler name and version etc. -<p class="level0">If CURLOPT_VERBOSE is not enough, you increase the level of debug data your application receive by using the CURLOPT_DEBUGFUNCTION. -<p class="level0">Getting some in-depth knowledge about the protocols involved is never wrong, and if you're trying to do funny things, you might very well understand libcurl and how to use it better if you study the appropriate RFC documents at least briefly. -<p class="level0"><a name="Upload"></a><h2 class="nroffsh">Upload Data to a Remote Site</h2> -<p class="level0">libcurl tries to keep a protocol independent approach to most transfers, thus uploading to a remote FTP site is very similar to uploading data to a HTTP server with a PUT request. -<p class="level0">Of course, first you either create an easy handle or you re-use one existing one. Then you set the URL to operate on just like before. This is the remote URL, that we now will upload. -<p class="level0">Since we write an application, we most likely want libcurl to get the upload data by asking us for it. To make it do that, we set the read callback and the custom pointer libcurl will pass to our read callback. The read callback should have a prototype similar to: -<p class="level0"> size_t function(char *bufptr, size_t size, size_t nitems, void *userp); -<p class="level0">Where bufptr is the pointer to a buffer we fill in with data to upload and size*nitems is the size of the buffer and therefore also the maximum amount of data we can return to libcurl in this call. The 'userp' pointer is the custom pointer we set to point to a struct of ours to pass private data between the application and the callback. -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_READFUNCTION, read_function); -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_READDATA, &filedata); -<p class="level0">Tell libcurl that we want to upload: -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_UPLOAD, 1L); -<p class="level0">A few protocols won't behave properly when uploads are done without any prior knowledge of the expected file size. So, set the upload file size using the CURLOPT_INFILESIZE_LARGE for all known file sizes like this[1]: -<p class="level0"> -<p class="level0"> /* in this example, file_size must be an curl_off_t variable */ curl_easy_setopt(easyhandle, CURLOPT_INFILESIZE_LARGE, file_size); -<p class="level0"> -<p class="level0">When you call <a class="emphasis" href="./curl_easy_perform.html">curl_easy_perform(3)</a> this time, it'll perform all the necessary operations and when it has invoked the upload it'll call your supplied callback to get the data to upload. The program should return as much data as possible in every invoke, as that is likely to make the upload perform as fast as possible. The callback should return the number of bytes it wrote in the buffer. Returning 0 will signal the end of the upload. -<p class="level0"><a name="Passwords"></a><h2 class="nroffsh">Passwords</h2> -<p class="level0">Many protocols use or even require that user name and password are provided to be able to download or upload the data of your choice. libcurl offers several ways to specify them. -<p class="level0">Most protocols support that you specify the name and password in the URL itself. libcurl will detect this and use them accordingly. This is written like this: -<p class="level0"> protocol://user:password@example.com/path/ -<p class="level0">If you need any odd letters in your user name or password, you should enter them URL encoded, as %XX where XX is a two-digit hexadecimal number. -<p class="level0">libcurl also provides options to set various passwords. The user name and password as shown embedded in the URL can instead get set with the CURLOPT_USERPWD option. The argument passed to libcurl should be a char * to a string in the format "user:password". In a manner like this: -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_USERPWD, "myname:thesecret"); -<p class="level0">Another case where name and password might be needed at times, is for those users who need to authenticate themselves to a proxy they use. libcurl offers another option for this, the CURLOPT_PROXYUSERPWD. It is used quite similar to the CURLOPT_USERPWD option like this: -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_PROXYUSERPWD, "myname:thesecret"); -<p class="level0">There's a long time UNIX "standard" way of storing ftp user names and passwords, namely in the $HOME/.netrc file. The file should be made private so that only the user may read it (see also the "Security Considerations" chapter), as it might contain the password in plain text. libcurl has the ability to use this file to figure out what set of user name and password to use for a particular host. As an extension to the normal functionality, libcurl also supports this file for non-FTP protocols such as HTTP. To make curl use this file, use the CURLOPT_NETRC option: -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_NETRC, 1L); -<p class="level0">And a very basic example of how such a .netrc file may look like: -<p class="level0"> -<p class="level0"> machine myhost.mydomain.com login userlogin password secretword -<p class="level0"> -<p class="level0">All these examples have been cases where the password has been optional, or at least you could leave it out and have libcurl attempt to do its job without it. There are times when the password isn't optional, like when you're using an SSL private key for secure transfers. -<p class="level0">To pass the known private key password to libcurl: -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_KEYPASSWD, "keypassword"); -<p class="level0"><a name="HTTP"></a><h2 class="nroffsh">HTTP Authentication</h2> -<p class="level0">The previous chapter showed how to set user name and password for getting URLs that require authentication. When using the HTTP protocol, there are many different ways a client can provide those credentials to the server and you can control which way libcurl will (attempt to) use them. The default HTTP authentication method is called 'Basic', which is sending the name and password in clear-text in the HTTP request, base64-encoded. This is insecure. -<p class="level0">At the time of this writing, libcurl can be built to use: Basic, Digest, NTLM, Negotiate, GSS-Negotiate and SPNEGO. You can tell libcurl which one to use with CURLOPT_HTTPAUTH as in: -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_HTTPAUTH, CURLAUTH_DIGEST); -<p class="level0">And when you send authentication to a proxy, you can also set authentication type the same way but instead with CURLOPT_PROXYAUTH: -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_PROXYAUTH, CURLAUTH_NTLM); -<p class="level0">Both these options allow you to set multiple types (by ORing them together), to make libcurl pick the most secure one out of the types the server/proxy claims to support. This method does however add a round-trip since libcurl must first ask the server what it supports: -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_HTTPAUTH, CURLAUTH_DIGEST|CURLAUTH_BASIC); -<p class="level0">For convenience, you can use the 'CURLAUTH_ANY' define (instead of a list with specific types) which allows libcurl to use whatever method it wants. -<p class="level0">When asking for multiple types, libcurl will pick the available one it considers "best" in its own internal order of preference. -<p class="level0"><a name="HTTP"></a><h2 class="nroffsh">HTTP POSTing</h2> -<p class="level0">We get many questions regarding how to issue HTTP POSTs with libcurl the proper way. This chapter will thus include examples using both different versions of HTTP POST that libcurl supports. -<p class="level0">The first version is the simple POST, the most common version, that most HTML pages using the <form> tag uses. We provide a pointer to the data and tell libcurl to post it all to the remote site: -<p class="level0"> -<p class="level0"> char *data="name=daniel&project=curl"; curl_easy_setopt(easyhandle, CURLOPT_POSTFIELDS, data); curl_easy_setopt(easyhandle, CURLOPT_URL, "<a href="http://posthere.com/">http://posthere.com/</a>"); -<p class="level0"> curl_easy_perform(easyhandle); /* post away! */ -<p class="level0"> -<p class="level0">Simple enough, huh? Since you set the POST options with the CURLOPT_POSTFIELDS, this automatically switches the handle to use POST in the upcoming request. -<p class="level0">Ok, so what if you want to post binary data that also requires you to set the Content-Type: header of the post? Well, binary posts prevent libcurl from being able to do strlen() on the data to figure out the size, so therefore we must tell libcurl the size of the post data. Setting headers in libcurl requests are done in a generic way, by building a list of our own headers and then passing that list to libcurl. -<p class="level0"> -<p class="level0"> struct curl_slist *headers=NULL; headers = curl_slist_append(headers, "Content-Type: text/xml"); -<p class="level0"> /* post binary data */ curl_easy_setopt(easyhandle, CURLOPT_POSTFIELDS, binaryptr); -<p class="level0"> /* set the size of the postfields data */ curl_easy_setopt(easyhandle, CURLOPT_POSTFIELDSIZE, 23L); -<p class="level0"> /* pass our list of custom made headers */ curl_easy_setopt(easyhandle, CURLOPT_HTTPHEADER, headers); -<p class="level0"> curl_easy_perform(easyhandle); /* post away! */ -<p class="level0"> curl_slist_free_all(headers); /* free the header list */ -<p class="level0"> -<p class="level0">While the simple examples above cover the majority of all cases where HTTP POST operations are required, they don't do multi-part formposts. Multi-part formposts were introduced as a better way to post (possibly large) binary data and were first documented in the <a href="http://www.ietf.org/rfc/rfc1867.txt">RFC 1867</a> (updated in RFC2388). They're called multi-part because they're built by a chain of parts, each part being a single unit of data. Each part has its own name and contents. You can in fact create and post a multi-part formpost with the regular libcurl POST support described above, but that would require that you build a formpost yourself and provide to libcurl. To make that easier, libcurl provides <a class="emphasis" href="./curl_formadd.html">curl_formadd(3)</a>. Using this function, you add parts to the form. When you're done adding parts, you post the whole form. -<p class="level0">The following example sets two simple text parts with plain textual contents, and then a file with binary contents and uploads the whole thing. -<p class="level0"> -<p class="level0"> struct curl_httppost *post=NULL; struct curl_httppost *last=NULL; curl_formadd(&post, &last, CURLFORM_COPYNAME, "name", CURLFORM_COPYCONTENTS, "daniel", CURLFORM_END); curl_formadd(&post, &last, CURLFORM_COPYNAME, "project", CURLFORM_COPYCONTENTS, "curl", CURLFORM_END); curl_formadd(&post, &last, CURLFORM_COPYNAME, "logotype-image", CURLFORM_FILECONTENT, "curl.png", CURLFORM_END); -<p class="level0"> /* Set the form info */ curl_easy_setopt(easyhandle, CURLOPT_HTTPPOST, post); -<p class="level0"> curl_easy_perform(easyhandle); /* post away! */ -<p class="level0"> /* free the post data again */ curl_formfree(post); -<p class="level0"> -<p class="level0">Multipart formposts are chains of parts using MIME-style separators and headers. It means that each one of these separate parts get a few headers set that describe the individual content-type, size etc. To enable your application to handicraft this formpost even more, libcurl allows you to supply your own set of custom headers to such an individual form part. You can of course supply headers to as many parts as you like, but this little example will show how you set headers to one specific part when you add that to the post handle: -<p class="level0"> -<p class="level0"> struct curl_slist *headers=NULL; headers = curl_slist_append(headers, "Content-Type: text/xml"); -<p class="level0"> curl_formadd(&post, &last, CURLFORM_COPYNAME, "logotype-image", CURLFORM_FILECONTENT, "curl.xml", CURLFORM_CONTENTHEADER, headers, CURLFORM_END); -<p class="level0"> curl_easy_perform(easyhandle); /* post away! */ -<p class="level0"> curl_formfree(post); /* free post */ curl_slist_free_all(headers); /* free custom header list */ -<p class="level0"> -<p class="level0">Since all options on an easyhandle are "sticky", they remain the same until changed even if you do call <a class="emphasis" href="./curl_easy_perform.html">curl_easy_perform(3)</a>, you may need to tell curl to go back to a plain GET request if you intend to do one as your next request. You force an easyhandle to go back to GET by using the CURLOPT_HTTPGET option: -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_HTTPGET, 1L); -<p class="level0">Just setting CURLOPT_POSTFIELDS to "" or NULL will *not* stop libcurl from doing a POST. It will just make it POST without any data to send! -<p class="level0"><a name="Showing"></a><h2 class="nroffsh">Showing Progress</h2> -<p class="level0"> -<p class="level0">For historical and traditional reasons, libcurl has a built-in progress meter that can be switched on and then makes it present a progress meter in your terminal. -<p class="level0">Switch on the progress meter by, oddly enough, setting CURLOPT_NOPROGRESS to zero. This option is set to 1 by default. -<p class="level0">For most applications however, the built-in progress meter is useless and what instead is interesting is the ability to specify a progress callback. The function pointer you pass to libcurl will then be called on irregular intervals with information about the current transfer. -<p class="level0">Set the progress callback by using CURLOPT_PROGRESSFUNCTION. And pass a pointer to a function that matches this prototype: -<p class="level0"> -<p class="level0"> int progress_callback(void *clientp, double dltotal, double dlnow, double ultotal, double ulnow); -<p class="level0"> -<p class="level0">If any of the input arguments is unknown, a 0 will be passed. The first argument, the 'clientp' is the pointer you pass to libcurl with CURLOPT_PROGRESSDATA. libcurl won't touch it. -<p class="level0"><a name="libcurl"></a><h2 class="nroffsh">libcurl with C++</h2> -<p class="level0"> -<p class="level0">There's basically only one thing to keep in mind when using C++ instead of C when interfacing libcurl: -<p class="level0">The callbacks CANNOT be non-static class member functions -<p class="level0">Example C++ code: -<p class="level0"> -<p class="level0">class AClass { static size_t write_data(void *ptr, size_t size, size_t nmemb, void *ourpointer) { /* do what you want with the data */ } } -<p class="level0"> -<p class="level0"><a name="Proxies"></a><h2 class="nroffsh">Proxies</h2> -<p class="level0"> -<p class="level0">What "proxy" means according to Merriam-Webster: "a person authorized to act for another" but also "the agency, function, or office of a deputy who acts as a substitute for another". -<p class="level0">Proxies are exceedingly common these days. Companies often only offer Internet access to employees through their proxies. Network clients or user-agents ask the proxy for documents, the proxy does the actual request and then it returns them. -<p class="level0">libcurl supports SOCKS and HTTP proxies. When a given URL is wanted, libcurl will ask the proxy for it instead of trying to connect to the actual host identified in the URL. -<p class="level0">If you're using a SOCKS proxy, you may find that libcurl doesn't quite support all operations through it. -<p class="level0">For HTTP proxies: the fact that the proxy is a HTTP proxy puts certain restrictions on what can actually happen. A requested URL that might not be a HTTP URL will be still be passed to the HTTP proxy to deliver back to libcurl. This happens transparently, and an application may not need to know. I say "may", because at times it is very important to understand that all operations over a HTTP proxy use the HTTP protocol. For example, you can't invoke your own custom FTP commands or even proper FTP directory listings. -<p class="level0"> -<p class="level0"><a name="Proxy"></a><span class="nroffip">Proxy Options</span> -<p class="level1"> -<p class="level1">To tell libcurl to use a proxy at a given port number: -<p class="level1"> curl_easy_setopt(easyhandle, CURLOPT_PROXY, "proxy-host.com:8080"); -<p class="level1">Some proxies require user authentication before allowing a request, and you pass that information similar to this: -<p class="level1"> curl_easy_setopt(easyhandle, CURLOPT_PROXYUSERPWD, "user:password"); -<p class="level1">If you want to, you can specify the host name only in the CURLOPT_PROXY option, and set the port number separately with CURLOPT_PROXYPORT. -<p class="level1">Tell libcurl what kind of proxy it is with CURLOPT_PROXYTYPE (if not, it will default to assume a HTTP proxy): -<p class="level1"> curl_easy_setopt(easyhandle, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS4); -<p class="level1"> -<p class="level0"><a name="Environment"></a><span class="nroffip">Environment Variables</span> -<p class="level1"> -<p class="level1">libcurl automatically checks and uses a set of environment variables to know what proxies to use for certain protocols. The names of the variables are following an ancient de facto standard and are built up as "[protocol]_proxy" (note the lower casing). Which makes the variable 'http_proxy' checked for a name of a proxy to use when the input URL is HTTP. Following the same rule, the variable named 'ftp_proxy' is checked for FTP URLs. Again, the proxies are always HTTP proxies, the different names of the variables simply allows different HTTP proxies to be used. -<p class="level1">The proxy environment variable contents should be in the format "[protocol://][user:password@]machine[:port]". Where the protocol:// part is simply ignored if present (so <a href="http://proxy">http://proxy</a> and bluerk://proxy will do the same) and the optional port number specifies on which port the proxy operates on the host. If not specified, the internal default port number will be used and that is most likely *not* the one you would like it to be. -<p class="level1">There are two special environment variables. 'all_proxy' is what sets proxy for any URL in case the protocol specific variable wasn't set, and 'no_proxy' defines a list of hosts that should not use a proxy even though a variable may say so. If 'no_proxy' is a plain asterisk ("*") it matches all hosts. -<p class="level1">To explicitly disable libcurl's checking for and using the proxy environment variables, set the proxy name to "" - an empty string - with CURLOPT_PROXY. -<p class="level0"><a name="SSL"></a><span class="nroffip">SSL and Proxies</span> -<p class="level1"> -<p class="level1">SSL is for secure point-to-point connections. This involves strong encryption and similar things, which effectively makes it impossible for a proxy to operate as a "man in between" which the proxy's task is, as previously discussed. Instead, the only way to have SSL work over a HTTP proxy is to ask the proxy to tunnel trough everything without being able to check or fiddle with the traffic. -<p class="level1">Opening an SSL connection over a HTTP proxy is therefor a matter of asking the proxy for a straight connection to the target host on a specified port. This is made with the HTTP request CONNECT. ("please mr proxy, connect me to that remote host"). -<p class="level1">Because of the nature of this operation, where the proxy has no idea what kind of data that is passed in and out through this tunnel, this breaks some of the very few advantages that come from using a proxy, such as caching. Many organizations prevent this kind of tunneling to other destination port numbers than 443 (which is the default HTTPS port number). -<p class="level1"> -<p class="level0"><a name="Tunneling"></a><span class="nroffip">Tunneling Through Proxy</span> -<p class="level1">As explained above, tunneling is required for SSL to work and often even restricted to the operation intended for SSL; HTTPS. -<p class="level1">This is however not the only time proxy-tunneling might offer benefits to you or your application. -<p class="level1">As tunneling opens a direct connection from your application to the remote machine, it suddenly also re-introduces the ability to do non-HTTP operations over a HTTP proxy. You can in fact use things such as FTP upload or FTP custom commands this way. -<p class="level1">Again, this is often prevented by the administrators of proxies and is rarely allowed. -<p class="level1">Tell libcurl to use proxy tunneling like this: -<p class="level1"> curl_easy_setopt(easyhandle, CURLOPT_HTTPPROXYTUNNEL, 1L); -<p class="level1">In fact, there might even be times when you want to do plain HTTP operations using a tunnel like this, as it then enables you to operate on the remote server instead of asking the proxy to do so. libcurl will not stand in the way for such innovative actions either! -<p class="level1"> -<p class="level0"><a name="Proxy"></a><span class="nroffip">Proxy Auto-Config</span> -<p class="level1"> -<p class="level1">Netscape first came up with this. It is basically a web page (usually using a .pac extension) with a Javascript that when executed by the browser with the requested URL as input, returns information to the browser on how to connect to the URL. The returned information might be "DIRECT" (which means no proxy should be used), "PROXY host:port" (to tell the browser where the proxy for this particular URL is) or "SOCKS host:port" (to direct the browser to a SOCKS proxy). -<p class="level1">libcurl has no means to interpret or evaluate Javascript and thus it doesn't support this. If you get yourself in a position where you face this nasty invention, the following advice have been mentioned and used in the past: -<p class="level1">- Depending on the Javascript complexity, write up a script that translates it to another language and execute that. -<p class="level1">- Read the Javascript code and rewrite the same logic in another language. -<p class="level1">- Implement a Javascript interpreter; people have successfully used the Mozilla Javascript engine in the past. -<p class="level1">- Ask your admins to stop this, for a static proxy setup or similar. -<p class="level1"><a name="Persistence"></a><h2 class="nroffsh">Persistence Is The Way to Happiness</h2> -<p class="level0"> -<p class="level0">Re-cycling the same easy handle several times when doing multiple requests is the way to go. -<p class="level0">After each single <a class="emphasis" href="./curl_easy_perform.html">curl_easy_perform(3)</a> operation, libcurl will keep the connection alive and open. A subsequent request using the same easy handle to the same host might just be able to use the already open connection! This reduces network impact a lot. -<p class="level0">Even if the connection is dropped, all connections involving SSL to the same host again, will benefit from libcurl's session ID cache that drastically reduces re-connection time. -<p class="level0">FTP connections that are kept alive save a lot of time, as the command- response round-trips are skipped, and also you don't risk getting blocked without permission to login again like on many FTP servers only allowing N persons to be logged in at the same time. -<p class="level0">libcurl caches DNS name resolving results, to make lookups of a previously looked up name a lot faster. -<p class="level0">Other interesting details that improve performance for subsequent requests may also be added in the future. -<p class="level0">Each easy handle will attempt to keep the last few connections alive for a while in case they are to be used again. You can set the size of this "cache" with the CURLOPT_MAXCONNECTS option. Default is 5. There is very seldom any point in changing this value, and if you think of changing this it is often just a matter of thinking again. -<p class="level0">To force your upcoming request to not use an already existing connection (it will even close one first if there happens to be one alive to the same host you're about to operate on), you can do that by setting CURLOPT_FRESH_CONNECT to 1. In a similar spirit, you can also forbid the upcoming request to be "lying" around and possibly get re-used after the request by setting CURLOPT_FORBID_REUSE to 1. -<p class="level0"><a name="HTTP"></a><h2 class="nroffsh">HTTP Headers Used by libcurl</h2> -<p class="level0">When you use libcurl to do HTTP requests, it'll pass along a series of headers automatically. It might be good for you to know and understand these. You can replace or remove them by using the CURLOPT_HTTPHEADER option. -<p class="level0"> -<p class="level0"><a name="Host"></a><span class="nroffip">Host</span> -<p class="level1">This header is required by HTTP 1.1 and even many 1.0 servers and should be the name of the server we want to talk to. This includes the port number if anything but default. -<p class="level1"> -<p class="level0"><a name="Accept"></a><span class="nroffip">Accept</span> -<p class="level1">"*/*". -<p class="level1"> -<p class="level0"><a name="Expect"></a><span class="nroffip">Expect</span> -<p class="level1">When doing POST requests, libcurl sets this header to "100-continue" to ask the server for an "OK" message before it proceeds with sending the data part of the post. If the POSTed data amount is deemed "small", libcurl will not use this header. -<p class="level1"><a name="Customizing"></a><h2 class="nroffsh">Customizing Operations</h2> -<p class="level0">There is an ongoing development today where more and more protocols are built upon HTTP for transport. This has obvious benefits as HTTP is a tested and reliable protocol that is widely deployed and has excellent proxy-support. -<p class="level0">When you use one of these protocols, and even when doing other kinds of programming you may need to change the traditional HTTP (or FTP or...) manners. You may need to change words, headers or various data. -<p class="level0">libcurl is your friend here too. -<p class="level0"> -<p class="level0"><a name="CUSTOMREQUEST"></a><span class="nroffip">CUSTOMREQUEST</span> -<p class="level1">If just changing the actual HTTP request keyword is what you want, like when GET, HEAD or POST is not good enough for you, CURLOPT_CUSTOMREQUEST is there for you. It is very simple to use: -<p class="level1"> curl_easy_setopt(easyhandle, CURLOPT_CUSTOMREQUEST, "MYOWNREQUEST"); -<p class="level1">When using the custom request, you change the request keyword of the actual request you are performing. Thus, by default you make a GET request but you can also make a POST operation (as described before) and then replace the POST keyword if you want to. You're the boss. -<p class="level1"> -<p class="level0"><a name="Modify"></a><span class="nroffip">Modify Headers</span> -<p class="level1">HTTP-like protocols pass a series of headers to the server when doing the request, and you're free to pass any amount of extra headers that you think fit. Adding headers is this easy: -<p class="level1"> -<p class="level1"> struct curl_slist *headers=NULL; /* init to NULL is important */ -<p class="level1"> headers = curl_slist_append(headers, "Hey-server-hey: how are you?"); headers = curl_slist_append(headers, "X-silly-content: yes"); -<p class="level1"> /* pass our list of custom made headers */ curl_easy_setopt(easyhandle, CURLOPT_HTTPHEADER, headers); -<p class="level1"> curl_easy_perform(easyhandle); /* transfer http */ -<p class="level1"> curl_slist_free_all(headers); /* free the header list */ -<p class="level1"> -<p class="level1">... and if you think some of the internally generated headers, such as Accept: or Host: don't contain the data you want them to contain, you can replace them by simply setting them too: -<p class="level1"> -<p class="level1"> headers = curl_slist_append(headers, "Accept: Agent-007"); headers = curl_slist_append(headers, "Host: munged.host.line"); -<p class="level1"> -<p class="level1"> -<p class="level0"><a name="Delete"></a><span class="nroffip">Delete Headers</span> -<p class="level1">If you replace an existing header with one with no contents, you will prevent the header from being sent. For instance, if you want to completely prevent the "Accept:" header from being sent, you can disable it with code similar to this: -<p class="level1"> headers = curl_slist_append(headers, "Accept:"); -<p class="level1">Both replacing and canceling internal headers should be done with careful consideration and you should be aware that you may violate the HTTP protocol when doing so. -<p class="level1"> -<p class="level0"><a name="Enforcing"></a><span class="nroffip">Enforcing chunked transfer-encoding</span> -<p class="level1"> -<p class="level1">By making sure a request uses the custom header "Transfer-Encoding: chunked" when doing a non-GET HTTP operation, libcurl will switch over to "chunked" upload, even though the size of the data to upload might be known. By default, libcurl usually switches over to chunked upload automatically if the upload data size is unknown. -<p class="level1"> -<p class="level0"><a name="HTTP"></a><span class="nroffip">HTTP Version</span> -<p class="level1"> -<p class="level1">All HTTP requests includes the version number to tell the server which version we support. libcurl speaks HTTP 1.1 by default. Some very old servers don't like getting 1.1-requests and when dealing with stubborn old things like that, you can tell libcurl to use 1.0 instead by doing something like this: -<p class="level1"> curl_easy_setopt(easyhandle, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0); -<p class="level1"> -<p class="level0"><a name="FTP"></a><span class="nroffip">FTP Custom Commands</span> -<p class="level1"> -<p class="level1">Not all protocols are HTTP-like, and thus the above may not help you when you want to make, for example, your FTP transfers to behave differently. -<p class="level1">Sending custom commands to a FTP server means that you need to send the commands exactly as the FTP server expects them (<a href="http://www.ietf.org/rfc/rfc959.txt">RFC 959</a> is a good guide here), and you can only use commands that work on the control-connection alone. All kinds of commands that require data interchange and thus need a data-connection must be left to libcurl's own judgement. Also be aware that libcurl will do its very best to change directory to the target directory before doing any transfer, so if you change directory (with CWD or similar) you might confuse libcurl and then it might not attempt to transfer the file in the correct remote directory. -<p class="level1">A little example that deletes a given file before an operation: -<p class="level1"> -<p class="level1"> headers = curl_slist_append(headers, "DELE file-to-remove"); -<p class="level1"> /* pass the list of custom commands to the handle */ curl_easy_setopt(easyhandle, CURLOPT_QUOTE, headers); -<p class="level1"> curl_easy_perform(easyhandle); /* transfer ftp data! */ -<p class="level1"> curl_slist_free_all(headers); /* free the header list */ -<p class="level1"> -<p class="level1">If you would instead want this operation (or chain of operations) to happen _after_ the data transfer took place the option to <a class="emphasis" href="./curl_easy_setopt.html">curl_easy_setopt(3)</a> would instead be called CURLOPT_POSTQUOTE and used the exact same way. -<p class="level1">The custom FTP command will be issued to the server in the same order they are added to the list, and if a command gets an error code returned back from the server, no more commands will be issued and libcurl will bail out with an error code (CURLE_QUOTE_ERROR). Note that if you use CURLOPT_QUOTE to send commands before a transfer, no transfer will actually take place when a quote command has failed. -<p class="level1">If you set the CURLOPT_HEADER to 1, you will tell libcurl to get information about the target file and output "headers" about it. The headers will be in "HTTP-style", looking like they do in HTTP. -<p class="level1">The option to enable headers or to run custom FTP commands may be useful to combine with CURLOPT_NOBODY. If this option is set, no actual file content transfer will be performed. -<p class="level1"> -<p class="level0"><a name="FTP"></a><span class="nroffip">FTP Custom CUSTOMREQUEST</span> -<p class="level1">If you do want to list the contents of a FTP directory using your own defined FTP command, CURLOPT_CUSTOMREQUEST will do just that. "NLST" is the default one for listing directories but you're free to pass in your idea of a good alternative. -<p class="level1"><a name="Cookies"></a><h2 class="nroffsh">Cookies Without Chocolate Chips</h2> -<p class="level0">In the HTTP sense, a cookie is a name with an associated value. A server sends the name and value to the client, and expects it to get sent back on every subsequent request to the server that matches the particular conditions set. The conditions include that the domain name and path match and that the cookie hasn't become too old. -<p class="level0">In real-world cases, servers send new cookies to replace existing ones to update them. Server use cookies to "track" users and to keep "sessions". -<p class="level0">Cookies are sent from server to clients with the header Set-Cookie: and they're sent from clients to servers with the Cookie: header. -<p class="level0">To just send whatever cookie you want to a server, you can use CURLOPT_COOKIE to set a cookie string like this: -<p class="level0"> curl_easy_setopt(easyhandle, CURLOPT_COOKIE, "name1=var1; name2=var2;"); -<p class="level0">In many cases, that is not enough. You might want to dynamically save whatever cookies the remote server passes to you, and make sure those cookies are then used accordingly on later requests. -<p class="level0">One way to do this, is to save all headers you receive in a plain file and when you make a request, you tell libcurl to read the previous headers to figure out which cookies to use. Set the header file to read cookies from with CURLOPT_COOKIEFILE. -<p class="level0">The CURLOPT_COOKIEFILE option also automatically enables the cookie parser in libcurl. Until the cookie parser is enabled, libcurl will not parse or understand incoming cookies and they will just be ignored. However, when the parser is enabled the cookies will be understood and the cookies will be kept in memory and used properly in subsequent requests when the same handle is used. Many times this is enough, and you may not have to save the cookies to disk at all. Note that the file you specify to CURLOPT_COOKIEFILE doesn't have to exist to enable the parser, so a common way to just enable the parser and not read any cookies is to use the name of a file you know doesn't exist. -<p class="level0">If you would rather use existing cookies that you've previously received with your Netscape or Mozilla browsers, you can make libcurl use that cookie file as input. The CURLOPT_COOKIEFILE is used for that too, as libcurl will automatically find out what kind of file it is and act accordingly. -<p class="level0">Perhaps the most advanced cookie operation libcurl offers, is saving the entire internal cookie state back into a Netscape/Mozilla formatted cookie file. We call that the cookie-jar. When you set a file name with CURLOPT_COOKIEJAR, that file name will be created and all received cookies will be stored in it when <a class="emphasis" href="./curl_easy_cleanup.html">curl_easy_cleanup(3)</a> is called. This enables cookies to get passed on properly between multiple handles without any information getting lost. -<p class="level0"><a name="FTP"></a><h2 class="nroffsh">FTP Peculiarities We Need</h2> -<p class="level0"> -<p class="level0">FTP transfers use a second TCP/IP connection for the data transfer. This is usually a fact you can forget and ignore but at times this fact will come back to haunt you. libcurl offers several different ways to customize how the second connection is being made. -<p class="level0">libcurl can either connect to the server a second time or tell the server to connect back to it. The first option is the default and it is also what works best for all the people behind firewalls, NATs or IP-masquerading setups. libcurl then tells the server to open up a new port and wait for a second connection. This is by default attempted with EPSV first, and if that doesn't work it tries PASV instead. (EPSV is an extension to the original FTP spec and does not exist nor work on all FTP servers.) -<p class="level0">You can prevent libcurl from first trying the EPSV command by setting CURLOPT_FTP_USE_EPSV to zero. -<p class="level0">In some cases, you will prefer to have the server connect back to you for the second connection. This might be when the server is perhaps behind a firewall or something and only allows connections on a single port. libcurl then informs the remote server which IP address and port number to connect to. This is made with the CURLOPT_FTPPORT option. If you set it to "-", libcurl will use your system's "default IP address". If you want to use a particular IP, you can set the full IP address, a host name to resolve to an IP address or even a local network interface name that libcurl will get the IP address from. -<p class="level0">When doing the "PORT" approach, libcurl will attempt to use the EPRT and the LPRT before trying PORT, as they work with more protocols. You can disable this behavior by setting CURLOPT_FTP_USE_EPRT to zero. -<p class="level0"><a name="Headers"></a><h2 class="nroffsh">Headers Equal Fun</h2> -<p class="level0"> -<p class="level0">Some protocols provide "headers", meta-data separated from the normal data. These headers are by default not included in the normal data stream, but you can make them appear in the data stream by setting CURLOPT_HEADER to 1. -<p class="level0">What might be even more useful, is libcurl's ability to separate the headers from the data and thus make the callbacks differ. You can for example set a different pointer to pass to the ordinary write callback by setting CURLOPT_WRITEHEADER. -<p class="level0">Or, you can set an entirely separate function to receive the headers, by using CURLOPT_HEADERFUNCTION. -<p class="level0">The headers are passed to the callback function one by one, and you can depend on that fact. It makes it easier for you to add custom header parsers etc. -<p class="level0">"Headers" for FTP transfers equal all the FTP server responses. They aren't actually true headers, but in this case we pretend they are! ;-) -<p class="level0"><a name="Post"></a><h2 class="nroffsh">Post Transfer Information</h2> -<p class="level0"> -<p class="level0"> [ curl_easy_getinfo ] -<p class="level0"><a name="Security"></a><h2 class="nroffsh">Security Considerations</h2> -<p class="level0"> -<p class="level0">The libcurl project takes security seriously. The library is written with caution and precautions are taken to mitigate many kinds of risks encountered while operating with potentially malicious servers on the Internet. It is a powerful library, however, which allows application writers to make trade offs between ease of writing and exposure to potential risky operations. If used the right way, you can use libcurl to transfer data pretty safely. -<p class="level0">Many applications are used in closed networks where users and servers can be trusted, but many others are used on arbitrary servers and are fed input from potentially untrusted users. Following is a discussion about some risks in the ways in which applications commonly use libcurl and potential mitigations of those risks. It is by no means comprehensive, but shows classes of attacks that robust applications should consider. The Common Weakness Enumeration project at <a href="http://cwe.mitre.org/">http://cwe.mitre.org/</a> is a good reference for many of these and similar types of weaknesses of which application writers should be aware. -<p class="level0"> -<p class="level0"><a name="Command"></a><span class="nroffip">Command Lines</span> -<p class="level1">If you use a command line tool (such as curl) that uses libcurl, and you give options to the tool on the command line those options can very likely get read by other users of your system when they use 'ps' or other tools to list currently running processes. -<p class="level1">To avoid this problem, never feed sensitive things to programs using command line options. Write them to a protected file and use the -K option to avoid this. -<p class="level1"> -<p class="level0"><a name="netrc"></a><span class="nroffip">.netrc</span> -<p class="level1">.netrc is a pretty handy file/feature that allows you to login quickly and automatically to frequently visited sites. The file contains passwords in clear text and is a real security risk. In some cases, your .netrc is also stored in a home directory that is NFS mounted or used on another network based file system, so the clear text password will fly through your network every time anyone reads that file! -<p class="level1">To avoid this problem, don't use .netrc files and never store passwords in plain text anywhere. -<p class="level1"> -<p class="level0"><a name="Clear"></a><span class="nroffip">Clear Text Passwords</span> -<p class="level1">Many of the protocols libcurl supports send name and password unencrypted as clear text (HTTP Basic authentication, FTP, TELNET etc). It is very easy for anyone on your network or a network nearby yours to just fire up a network analyzer tool and eavesdrop on your passwords. Don't let the fact that HTTP Basic uses base64 encoded passwords fool you. They may not look readable at a first glance, but they very easily "deciphered" by anyone within seconds. -<p class="level1">To avoid this problem, use HTTP authentication methods or other protocols that don't let snoopers see your password: HTTP with Digest, NTLM or GSS authentication, HTTPS, FTPS, SCP, SFTP and FTP-Kerberos are a few examples. -<p class="level1"> -<p class="level0"><a name="Redirects"></a><span class="nroffip">Redirects</span> -<p class="level1">The CURLOPT_FOLLOWLOCATION option automatically follows HTTP redirects sent by a remote server. These redirects can refer to any kind of URL, not just HTTP. A redirect to a file: URL would cause the libcurl to read (or write) arbitrary files from the local filesystem. If the application returns the data back to the user (as would happen in some kinds of CGI scripts), an attacker could leverage this to read otherwise forbidden data (e.g. file://localhost/etc/passwd). -<p class="level1">If authentication credentials are stored in the ~/.netrc file, or Kerberos is in use, any other URL type (not just file:) that requires authentication is also at risk. A redirect such as <a href="ftp://some-internal-server/private-file">ftp://some-internal-server/private-file</a> would then return data even when the server is password protected. -<p class="level1">In the same way, if an unencrypted SSH private key has been configured for the user running the libcurl application, SCP: or SFTP: URLs could access password or private-key protected resources, e.g. s<a href="ftp://user">ftp://user</a>@some-internal-server/etc/passwd -<p class="level1">The CURLOPT_REDIR_PROTOCOLS and CURLOPT_NETRC options can be used to mitigate against this kind of attack. -<p class="level1">A redirect can also specify a location available only on the machine running libcurl, including servers hidden behind a firewall from the attacker. e.g. <a href="http://127.0.0.1/">http://127.0.0.1/</a> or <a href="http://intranet/delete-stuff.cgi">http://intranet/delete-stuff.cgi</a>?delete=all or t<a href="ftp://bootp-server/pc-config-data">ftp://bootp-server/pc-config-data</a> -<p class="level1">Apps can mitigate against this by disabling CURLOPT_FOLLOWLOCATION and handling redirects itself, sanitizing URLs as necessary. Alternately, an app could leave CURLOPT_FOLLOWLOCATION enabled but set CURLOPT_REDIR_PROTOCOLS and install a CURLOPT_OPENSOCKETFUNCTION callback function in which addresses are sanitized before use. -<p class="level1"> -<p class="level0"><a name="Private"></a><span class="nroffip">Private Resources</span> -<p class="level1">A user who can control the DNS server of a domain being passed in within a URL can change the address of the host to a local, private address which the libcurl application will then use. e.g. The innocuous URL <a href="http://fuzzybunnies.example.com/">http://fuzzybunnies.example.com/</a> could actually resolve to the IP address of a server behind a firewall, such as 127.0.0.1 or 10.1.2.3 Apps can mitigate against this by setting a CURLOPT_OPENSOCKETFUNCTION and checking the address before a connection. -<p class="level1">All the malicious scenarios regarding redirected URLs apply just as well to non-redirected URLs, if the user is allowed to specify an arbitrary URL that could point to a private resource. For example, a web app providing a translation service might happily translate file://localhost/etc/passwd and display the result. Apps can mitigate against this with the CURLOPT_PROTOCOLS option as well as by similar mitigation techniques for redirections. -<p class="level1">A malicious FTP server could in response to the PASV command return an IP address and port number for a server local to the app running libcurl but behind a firewall. Apps can mitigate against this by using the CURLOPT_FTP_SKIP_PASV_IP option or CURLOPT_FTPPORT. -<p class="level1"> -<p class="level0"><a name="Uploads"></a><span class="nroffip">Uploads</span> -<p class="level1">When uploading, a redirect can cause a local (or remote) file to be overwritten. Apps must not allow any unsanitized URL to be passed in for uploads. Also, CURLOPT_FOLLOWLOCATION should not be used on uploads. Instead, the app should handle redirects itself, sanitizing each URL first. -<p class="level1"> -<p class="level0"><a name="Authentication"></a><span class="nroffip">Authentication</span> -<p class="level1">Use of CURLOPT_UNRESTRICTED_AUTH could cause authentication information to be sent to an unknown second server. Apps can mitigate against this by disabling CURLOPT_FOLLOWLOCATION and handling redirects itself, sanitizing where necessary. -<p class="level1">Use of the CURLAUTH_ANY option to CURLOPT_HTTPAUTH could result in user name and password being sent in clear text to an HTTP server. Instead, use CURLAUTH_ANYSAFE which ensures that the password is encrypted over the network, or else fail the request. -<p class="level1">Use of the CURLUSESSL_TRY option to CURLOPT_USE_SSL could result in user name and password being sent in clear text to an FTP server. Instead, use CURLUSESSL_CONTROL to ensure that an encrypted connection is used or else fail the request. -<p class="level1"> -<p class="level0"><a name="Cookies"></a><span class="nroffip">Cookies</span> -<p class="level1">If cookies are enabled and cached, then a user could craft a URL which performs some malicious action to a site whose authentication is already stored in a cookie. e.g. <a href="http://mail.example.com/delete-stuff.cgi">http://mail.example.com/delete-stuff.cgi</a>?delete=all Apps can mitigate against this by disabling cookies or clearing them between requests. -<p class="level1"> -<p class="level0"><a name="Dangerous"></a><span class="nroffip">Dangerous URLs</span> -<p class="level1">SCP URLs can contain raw commands within the scp: URL, which is a side effect of how the SCP protocol is designed. e.g. scp://user:pass@host/a;date >/tmp/test; Apps must not allow unsanitized SCP: URLs to be passed in for downloads. -<p class="level1"> -<p class="level0"><a name="Denial"></a><span class="nroffip">Denial of Service</span> -<p class="level1">A malicious server could cause libcurl to effectively hang by sending a trickle of data through, or even no data at all but just keeping the TCP connection open. This could result in a denial-of-service attack. The CURLOPT_TIMEOUT and/or CURLOPT_LOW_SPEED_LIMIT options can be used to mitigate against this. -<p class="level1">A malicious server could cause libcurl to effectively hang by starting to send data, then severing the connection without cleanly closing the TCP connection. The app could install a CURLOPT_SOCKOPTFUNCTION callback function and set the TCP SO_KEEPALIVE option to mitigate against this. Setting one of the timeout options would also work against this attack. -<p class="level1">A malicious server could cause libcurl to download an infinite amount of data, potentially causing all of memory or disk to be filled. Setting the CURLOPT_MAXFILESIZE_LARGE option is not sufficient to guard against this. Instead, the app should monitor the amount of data received within the write or progress callback and abort once the limit is reached. -<p class="level1">A malicious HTTP server could cause an infinite redirection loop, causing a denial-of-service. This can be mitigated by using the CURLOPT_MAXREDIRS option. -<p class="level1"> -<p class="level0"><a name="Arbitrary"></a><span class="nroffip">Arbitrary Headers</span> -<p class="level1">User-supplied data must be sanitized when used in options like CURLOPT_USERAGENT, CURLOPT_HTTPHEADER, CURLOPT_POSTFIELDS and others that are used to generate structured data. Characters like embedded carriage returns or ampersands could allow the user to create additional headers or fields that could cause malicious transactions. -<p class="level1"> -<p class="level0"><a name="Server-supplied"></a><span class="nroffip">Server-supplied Names</span> -<p class="level1">A server can supply data which the application may, in some cases, use as a file name. The curl command-line tool does this with --remote-header-name, using the Content-disposition: header to generate a file name. An application could also use CURLINFO_EFFECTIVE_URL to generate a file name from a server-supplied redirect URL. Special care must be taken to sanitize such names to avoid the possibility of a malicious server supplying one like "/etc/passwd", "autoexec.bat" or even ".bashrc". -<p class="level1"> -<p class="level0"><a name="Server"></a><span class="nroffip">Server Certificates</span> -<p class="level1">A secure application should never use the CURLOPT_SSL_VERIFYPEER option to disable certificate validation. There are numerous attacks that are enabled by apps that fail to properly validate server TLS/SSL certificates, thus enabling a malicious server to spoof a legitimate one. HTTPS without validated certificates is potentially as insecure as a plain HTTP connection. -<p class="level1"> -<p class="level0"><a name="Showing"></a><span class="nroffip">Showing What You Do</span> -<p class="level1">On a related issue, be aware that even in situations like when you have problems with libcurl and ask someone for help, everything you reveal in order to get best possible help might also impose certain security related risks. Host names, user names, paths, operating system specifics, etc (not to mention passwords of course) may in fact be used by intruders to gain additional information of a potential target. -<p class="level1">To avoid this problem, you must of course use your common sense. Often, you can just edit out the sensitive data or just search/replace your true information with faked data. -<p class="level1"><a name="Multiple"></a><h2 class="nroffsh">Multiple Transfers Using the multi Interface</h2> -<p class="level0"> -<p class="level0">The easy interface as described in detail in this document is a synchronous interface that transfers one file at a time and doesn't return until it is done. -<p class="level0">The multi interface, on the other hand, allows your program to transfer multiple files in both directions at the same time, without forcing you to use multiple threads. The name might make it seem that the multi interface is for multi-threaded programs, but the truth is almost the reverse. The multi interface can allow a single-threaded application to perform the same kinds of multiple, simultaneous transfers that multi-threaded programs can perform. It allows many of the benefits of multi-threaded transfers without the complexity of managing and synchronizing many threads. -<p class="level0">To use this interface, you are better off if you first understand the basics of how to use the easy interface. The multi interface is simply a way to make multiple transfers at the same time by adding up multiple easy handles into a "multi stack". -<p class="level0">You create the easy handles you want and you set all the options just like you have been told above, and then you create a multi handle with <a class="emphasis" href="./curl_multi_init.html">curl_multi_init(3)</a> and add all those easy handles to that multi handle with <a class="emphasis" href="./curl_multi_add_handle.html">curl_multi_add_handle(3)</a>. -<p class="level0">When you've added the handles you have for the moment (you can still add new ones at any time), you start the transfers by calling <a class="emphasis" href="./curl_multi_perform.html">curl_multi_perform(3)</a>. -<p class="level0"><a class="emphasis" href="./curl_multi_perform.html">curl_multi_perform(3)</a> is asynchronous. It will only execute as little as possible and then return back control to your program. It is designed to never block. -<p class="level0">The best usage of this interface is when you do a select() on all possible file descriptors or sockets to know when to call libcurl again. This also makes it easy for you to wait and respond to actions on your own application's sockets/handles. You figure out what to select() for by using <a class="emphasis" href="./curl_multi_fdset.html">curl_multi_fdset(3)</a>, that fills in a set of fd_set variables for you with the particular file descriptors libcurl uses for the moment. -<p class="level0">When you then call select(), it'll return when one of the file handles signal action and you then call <a class="emphasis" href="./curl_multi_perform.html">curl_multi_perform(3)</a> to allow libcurl to do what it wants to do. Take note that libcurl does also feature some time-out code so we advise you to never use very long timeouts on select() before you call <a class="emphasis" href="./curl_multi_perform.html">curl_multi_perform(3)</a>, which thus should be called unconditionally every now and then even if none of its file descriptors have signaled ready. Another precaution you should use: always call <a class="emphasis" href="./curl_multi_fdset.html">curl_multi_fdset(3)</a> immediately before the select() call since the current set of file descriptors may change when calling a curl function. -<p class="level0">If you want to stop the transfer of one of the easy handles in the stack, you can use <a class="emphasis" href="./curl_multi_remove_handle.html">curl_multi_remove_handle(3)</a> to remove individual easy handles. Remember that easy handles should be <a class="emphasis" href="./curl_easy_cleanup.html">curl_easy_cleanup(3)</a>ed. -<p class="level0">When a transfer within the multi stack has finished, the counter of running transfers (as filled in by <a class="emphasis" href="./curl_multi_perform.html">curl_multi_perform(3)</a>) will decrease. When the number reaches zero, all transfers are done. -<p class="level0"><a class="emphasis" href="./curl_multi_info_read.html">curl_multi_info_read(3)</a> can be used to get information about completed transfers. It then returns the CURLcode for each easy transfer, to allow you to figure out success on each individual transfer. -<p class="level0"><a name="SSL"></a><h2 class="nroffsh">SSL, Certificates and Other Tricks</h2> -<p class="level0"> -<p class="level0"> [ seeding, passwords, keys, certificates, ENGINE, ca certs ] -<p class="level0"><a name="Sharing"></a><h2 class="nroffsh">Sharing Data Between Easy Handles</h2> -<p class="level0">You can share some data between easy handles when the easy interface is used, and some data is share automatically when you use the multi interface. -<p class="level0">When you add easy handles to a multi handle, these easy handles will automatically share a lot of the data that otherwise would be kept on a per-easy handle basis when the easy interface is used. -<p class="level0">The DNS cache is shared between handles within a multi handle, making subsequent name resolvings faster and the connection pool that is kept to better allow persistent connections and connection re-use is shared.

Look elsewhere for documentation on those. - -libcurl has a global constant environment that you must set up and -maintain while using libcurl. This essentially means you call -\fIcurl_global_init(3)\fP at the start of your program and -\fIcurl_global_cleanup(3)\fP at the end. See GLOBAL CONSTANTS below -for details. - -To transfer files, you always set up an "easy handle" using -\fIcurl_easy_init(3)\fP, but when you want the file(s) transferred you have -the option of using the "easy" interface, or the "multi" interface. - -The easy interface is a synchronous interface with which you call -\fIcurl_easy_perform(3)\fP and let it perform the transfer.

The multi interface allows you to select() on libcurl action, and -even to easily download multiple files simultaneously using a single thread. See further details in the \fIlibcurl-multi(3)\fP man page. - -You can have multiple easy handles share certain data, even if they are used -in different threads. This magic is setup using the share interface, as -described in the \fIlibcurl-share(3)\fP man page. - -There is also a series of other helpful functions to use, including these: -.RS -.IP curl_version_info() -gets detailed libcurl (and other used libraries) version info -.IP curl_getdate() -converts a date string to time_t -.IP curl_easy_getinfo() -get information about a performed transfer -.IP curl_formadd() -helps building an HTTP form POST -.IP curl_formfree() -free a list built with \fIcurl_formadd(3)\fP -.IP curl_slist_append() -builds a linked list -.IP curl_slist_free_all() -frees a whole curl_slist -.RE - -.SH "LINKING WITH LIBCURL" -On unix-like machines, there's a tool named curl-config that gets installed -with the rest of the curl stuff when 'make install' is performed. - -curl-config is added to make it easier for applications to link with libcurl -and developers to learn about libcurl and how to use it. - -Run 'curl-config --libs' to get the (additional) linker options you need to -link with the particular version of libcurl you've installed. See the -\fIcurl-config(1)\fP man page for further details. - -Unix-like operating system that ship libcurl as part of their distributions -often don't provide the curl-config tool, but simply install the library and -headers in the common path for this purpose. - -.SH "LIBCURL SYMBOL NAMES" -All public functions in the libcurl interface are prefixed with 'curl_' (with -a lowercase c). You can find other functions in the library source code, but -other prefixes indicate that the functions are private and may change without -further notice in the next release. - -Only use documented functions and functionality! -.SH "PORTABILITY" -libcurl works -.B exactly -the same, on any of the platforms it compiles and builds on. -.SH "THREADS" -Never ever call curl-functions simultaneously using the same handle from -several threads. libcurl is thread-safe and can be used in any number of -threads, but you must use separate curl handles if you want to use libcurl in -more than one thread simultaneously. - -The global environment functions are not thread-safe. See GLOBAL CONSTANTS -below for details. - -.SH "PERSISTENT CONNECTIONS" -Persistent connections means that libcurl can re-use the same connection for -several transfers, if the conditions are right. - -libcurl will \fBalways\fP attempt to use persistent connections. Whenever you -use \fIcurl_easy_perform(3)\fP or \fIcurl_multi_perform(3)\fP, libcurl will -attempt to use an existing connection to do the transfer, and if none exists -it'll open a new one that will be subject for re-use on a possible following -call to \fIcurl_easy_perform(3)\fP or \fIcurl_multi_perform(3)\fP. - -To allow libcurl to take full advantage of persistent connections, you should -do as many of your file transfers as possible using the same curl handle. When -you call \fIcurl_easy_cleanup(3)\fP, all the possibly open connections held by -libcurl will be closed and forgotten. - -Note that the options set with \fIcurl_easy_setopt(3)\fP will be used on -every repeated \fIcurl_easy_perform(3)\fP call. - -.SH "GLOBAL CONSTANTS" -There are a variety of constants that libcurl uses, mainly through its -internal use of other libraries, which are too complicated for the -library loader to set up. Therefore, a program must call a library -function after the program is loaded and running to finish setting up -the library code. For example, when libcurl is built for SSL -capability via the GNU TLS library, there is an elaborate tree inside -that library that describes the SSL protocol. - -\fIcurl_global_init()\fP is the function that you must call. This may -allocate resources (e.g. the memory for the GNU TLS tree mentioned -above), so the companion function \fIcurl_global_cleanup()\fP releases -them. - -The basic rule for constructing a program that uses libcurl is this: -Call \fIcurl_global_init()\fP, with a \fICURL_GLOBAL_ALL\fP argument, -immediately after the program starts, while it is still only one -thread and before it uses libcurl at all. Call -\fIcurl_global_cleanup()\fP immediately before the program exits, when -the program is again only one thread and after its last use of -libcurl. - -You can call both of these multiple times, as long as all calls meet -these requirements and the number of calls to each is the same. - -It isn't actually required that the functions be called at the beginning -and end of the program -- that's just usually the easiest way to do it. -It \fIis\fP required that the functions be called when no other thread -in the program is running. - -These global constant functions are \fInot thread safe\fP, so you must -not call them when any other thread in the program is running. It -isn't good enough that no other thread is using libcurl at the time, -because these functions internally call similar functions of other -libraries, and those functions are similarly thread-unsafe. You can't -generally know what these libraries are, or whether other threads are -using them. - -The global constant situation merits special consideration when the -code you are writing to use libcurl is not the main program, but rather -a modular piece of a program, e.g. another library. As a module, -your code doesn't know about other parts of the program -- it doesn't -know whether they use libcurl or not. And its code doesn't necessarily -run at the start and end of the whole program. - -A module like this must have global constant functions of its own, -just like \fIcurl_global_init()\fP and \fIcurl_global_cleanup()\fP. -The module thus has control at the beginning and end of the program -and has a place to call the libcurl functions. Note that if multiple -modules in the program use libcurl, they all will separately call the -libcurl functions, and that's OK because only the first -\fIcurl_global_init()\fP and the last \fIcurl_global_cleanup()\fP in a -program change anything. (libcurl uses a reference count in static -memory). - -In a C++ module, it is common to deal with the global constant -situation by defining a special class that represents the global -constant environment of the module. A program always has exactly one -object of the class, in static storage. That way, the program -automatically calls the constructor of the object as the program -starts up and the destructor as it terminates. As the author of this -libcurl-using module, you can make the constructor call -\fIcurl_global_init()\fP and the destructor call -\fIcurl_global_cleanup()\fP and satisfy libcurl's requirements without -your user having to think about it. - -\fIcurl_global_init()\fP has an argument that tells what particular -parts of the global constant environment to set up. In order to -successfully use any value except \fICURL_GLOBAL_ALL\fP (which says to -set up the whole thing), you must have specific knowledge of internal -workings of libcurl and all other parts of the program of which it is -part. - -A special part of the global constant environment is the identity of -the memory allocator. \fIcurl_global_init()\fP selects the system -default memory allocator, but you can use \fIcurl_global_init_mem()\fP -to supply one of your own. However, there is no way to use -\fIcurl_global_init_mem()\fP in a modular program -- all modules in -the program that might use libcurl would have to agree on one -allocator. - -There is a failsafe in libcurl that makes it usable in simple -situations without you having to worry about the global constant -environment at all: \fIcurl_easy_init()\fP sets up the environment -itself if it hasn't been done yet. The resources it acquires to do so -get released by the operating system automatically when the program -exits. - -This failsafe feature exists mainly for backward compatibility because -there was a time when the global functions didn't exist. Because it -is sufficient only in the simplest of programs, it is not recommended -for any program to rely on it. diff --git a/plugins/FTPFileYM/curl/docs/libcurl/libcurl.html b/plugins/FTPFileYM/curl/docs/libcurl/libcurl.html deleted file mode 100644 index e1c00f0d37..0000000000 --- a/plugins/FTPFileYM/curl/docs/libcurl/libcurl.html +++ /dev/null @@ -1,105 +0,0 @@ -<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" - "http://www.w3.org/TR/html4/loose.dtd"> -<html><head> -<title>libcurl man page</title> -<meta name="generator" content="roffit"> -<STYLE type="text/css"> -P.level0 { - padding-left: 2em; -} - -P.level1 { - padding-left: 4em; -} - -P.level2 { - padding-left: 6em; -} - -span.emphasis { - font-style: italic; -} - -span.bold { - font-weight: bold; -} - -span.manpage { - font-weight: bold; -} - -h2.nroffsh { - background-color: #e0e0e0; -} - -span.nroffip { - font-weight: bold; - font-size: 120%; - font-family: monospace; -} - -p.roffit { - text-align: center; - font-size: 80%; -} -</STYLE> -</head><body> - -<p class="level0"><a name="NAME"></a><h2 class="nroffsh">NAME</h2> -<p class="level0">libcurl - client-side URL transfers <a name="DESCRIPTION"></a><h2 class="nroffsh">DESCRIPTION</h2> -<p class="level0">This is a short overview on how to use libcurl in your C programs.

See the <span Class="emphasis">curl-config(1)</span> man page for further details. -<p class="level0">Unix-like operating system that ship libcurl as part of their distributions often don't provide the curl-config tool, but simply install the library and headers in the common path for this purpose. -<p class="level0"><a name="LIBCURL"></a><h2 class="nroffsh">LIBCURL SYMBOL NAMES</h2> -<p class="level0">All public functions in the libcurl interface are prefixed with 'curl_' (with a lowercase c). You can find other functions in the library source code, but other prefixes indicate that the functions are private and may change without further notice in the next release. -<p class="level0">Only use documented functions and functionality! <a name="PORTABILITY"></a><h2 class="nroffsh">PORTABILITY</h2> -<p class="level0">libcurl works <span Class="bold">exactly</span> the same, on any of the platforms it compiles and builds on. <a name="THREADS"></a><h2 class="nroffsh">THREADS</h2> -<p class="level0">Never ever call curl-functions simultaneously using the same handle from several threads. libcurl is thread-safe and can be used in any number of threads, but you must use separate curl handles if you want to use libcurl in more than one thread simultaneously. -<p class="level0">The global environment functions are not thread-safe. See GLOBAL CONSTANTS below for details. -<p class="level0"><a name="PERSISTENT"></a><h2 class="nroffsh">PERSISTENT CONNECTIONS</h2> -<p class="level0">Persistent connections means that libcurl can re-use the same connection for several transfers, if the conditions are right. -<p class="level0">libcurl will <span Class="bold">always</span> attempt to use persistent connections. Whenever you use <a class="emphasis" href="./curl_easy_perform.html">curl_easy_perform(3)</a> or <a class="emphasis" href="./curl_multi_perform.html">curl_multi_perform(3)</a>, libcurl will attempt to use an existing connection to do the transfer, and if none exists it'll open a new one that will be subject for re-use on a possible following call to <a class="emphasis" href="./curl_easy_perform.html">curl_easy_perform(3)</a> or <a class="emphasis" href="./curl_multi_perform.html">curl_multi_perform(3)</a>. -<p class="level0">To allow libcurl to take full advantage of persistent connections, you should do as many of your file transfers as possible using the same curl handle. When you call <a class="emphasis" href="./curl_easy_cleanup.html">curl_easy_cleanup(3)</a>, all the possibly open connections held by libcurl will be closed and forgotten. -<p class="level0">Note that the options set with <a class="emphasis" href="./curl_easy_setopt.html">curl_easy_setopt(3)</a> will be used on every repeated <a class="emphasis" href="./curl_easy_perform.html">curl_easy_perform(3)</a> call. -<p class="level0"><a name="GLOBAL"></a><h2 class="nroffsh">GLOBAL CONSTANTS</h2> -<p class="level0">There are a variety of constants that libcurl uses, mainly through its internal use of other libraries, which are too complicated for the library loader to set up. Therefore, a program must call a library function after the program is loaded and running to finish setting up the library code. For example, when libcurl is built for SSL capability via the GNU TLS library, there is an elaborate tree inside that library that describes the SSL protocol. -<p class="level0"><span Class="emphasis">curl_global_init()</span> is the function that you must call. This may allocate resources (e.g. the memory for the GNU TLS tree mentioned above), so the companion function <span Class="emphasis">curl_global_cleanup()</span> releases them. -<p class="level0">The basic rule for constructing a program that uses libcurl is this: Call <span Class="emphasis">curl_global_init()</span>, with a <span Class="emphasis">CURL_GLOBAL_ALL</span> argument, immediately after the program starts, while it is still only one thread and before it uses libcurl at all. Call <span Class="emphasis">curl_global_cleanup()</span> immediately before the program exits, when the program is again only one thread and after its last use of libcurl. -<p class="level0">You can call both of these multiple times, as long as all calls meet these requirements and the number of calls to each is the same. -<p class="level0">It isn't actually required that the functions be called at the beginning and end of the program -- that's just usually the easiest way to do it. It <span Class="emphasis">is</span> required that the functions be called when no other thread in the program is running. -<p class="level0">These global constant functions are <span Class="emphasis">not thread safe</span>, so you must not call them when any other thread in the program is running. It isn't good enough that no other thread is using libcurl at the time, because these functions internally call similar functions of other libraries, and those functions are similarly thread-unsafe. You can't generally know what these libraries are, or whether other threads are using them. -<p class="level0">The global constant situation merits special consideration when the code you are writing to use libcurl is not the main program, but rather a modular piece of a program, e.g. another library. As a module, your code doesn't know about other parts of the program -- it doesn't know whether they use libcurl or not. And its code doesn't necessarily run at the start and end of the whole program. -<p class="level0">A module like this must have global constant functions of its own, just like <span Class="emphasis">curl_global_init()</span> and <span Class="emphasis">curl_global_cleanup()</span>. The module thus has control at the beginning and end of the program and has a place to call the libcurl functions. Note that if multiple modules in the program use libcurl, they all will separately call the libcurl functions, and that's OK because only the first <span Class="emphasis">curl_global_init()</span> and the last <span Class="emphasis">curl_global_cleanup()</span> in a program change anything. (libcurl uses a reference count in static memory). -<p class="level0">In a C++ module, it is common to deal with the global constant situation by defining a special class that represents the global constant environment of the module. A program always has exactly one object of the class, in static storage. That way, the program automatically calls the constructor of the object as the program starts up and the destructor as it terminates. As the author of this libcurl-using module, you can make the constructor call <span Class="emphasis">curl_global_init()</span> and the destructor call <span Class="emphasis">curl_global_cleanup()</span> and satisfy libcurl's requirements without your user having to think about it. -<p class="level0"><span Class="emphasis">curl_global_init()</span> has an argument that tells what particular parts of the global constant environment to set up. In order to successfully use any value except <span Class="emphasis">CURL_GLOBAL_ALL</span> (which says to set up the whole thing), you must have specific knowledge of internal workings of libcurl and all other parts of the program of which it is part. -<p class="level0">A special part of the global constant environment is the identity of the memory allocator. <span Class="emphasis">curl_global_init()</span> selects the system default memory allocator, but you can use <span Class="emphasis">curl_global_init_mem()</span> to supply one of your own. However, there is no way to use <span Class="emphasis">curl_global_init_mem()</span> in a modular program -- all modules in the program that might use libcurl would have to agree on one allocator. -<p class="level0">There is a failsafe in libcurl that makes it usable in simple situations without you having to worry about the global constant environment at all: <span Class="emphasis">curl_easy_init()</span> sets up the environment itself if it hasn't been done yet. The resources it acquires to do so get released by the operating system automatically when the program exits. -<p class="level0">This failsafe feature exists mainly for backward compatibility because there was a time when the global functions didn't exist. Because it is sufficient only in the simplest of programs, it is not recommended for any program to rely on it. <p class="roffit"> - This HTML page was made with <a href="http://daniel.haxx.se/projects/roffit/">roffit</a>. -</body></html> diff --git a/plugins/FTPFileYM/curl/docs/libcurl/libcurl.m4 b/plugins/FTPFileYM/curl/docs/libcurl/libcurl.m4 deleted file mode 100644 index d7d5a52591..0000000000 --- a/plugins/FTPFileYM/curl/docs/libcurl/libcurl.m4 +++ /dev/null @@ -1,251 +0,0 @@ -# LIBCURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION], -# [ACTION-IF-YES], [ACTION-IF-NO]) -# ---------------------------------------------------------- -# David Shaw <dshaw@jabberwocky.com> May-09-2006 -# -# Checks for libcurl.
