You may +use it together with \fIcurl_easy_recv(3)\fP to implement custom protocols +using libcurl. This functionality can be particularly useful if you use +proxies and/or SSL encryption: libcurl will take care of proxy negotiation and +connection set-up. + +\fBbuffer\fP is a pointer to the data of length \fBbuflen\fP that you want sent. +The variable \fBn\fP points to will receive the number of sent bytes. + +To establish the connection, set \fBCURLOPT_CONNECT_ONLY\fP option before +calling \fIcurl_easy_perform(3)\fP. Note that \fIcurl_easy_send(3)\fP will not +work on connections that were created without this option. + +You must ensure that the socket is writable before calling +\fIcurl_easy_send(3)\fP, otherwise the call will return \fBCURLE_AGAIN\fP - +the socket is used in non-blocking mode internally. Use +\fIcurl_easy_getinfo(3)\fP with \fBCURLINFO_LASTSOCKET\fP to obtain the +socket; use your operating system facilities like \fIselect(2)\fP to check if +it can be written to. +.SH AVAILABILITY +Added in 7.18.2. +.SH RETURN VALUE +On success, returns \fBCURLE_OK\fP and stores the number of bytes actually +sent into \fB*n\fP. Note that this may very well be less than the amount you +wanted to send. + +On failure, returns the appropriate error code. + +If there's no socket available to use from the previous transfer, this function +returns CURLE_UNSUPPORTED_PROTOCOL. +.SH EXAMPLE +See \fBsendrecv.c\fP in \fBdocs/examples\fP directory for usage example. +.SH "SEE ALSO" +.BR curl_easy_setopt "(3), " curl_easy_perform "(3), " curl_easy_getinfo "(3), " +.BR curl_easy_recv "(3) " |
