There are specific man pages for each function mentioned in +here. + +All functions in the share interface are prefixed with curl_share. + +.SH "OBJECTIVES" +The share interface was added to enable sharing of data between curl +\&"handles". +.SH "ONE SET OF DATA - MANY TRANSFERS" +You can have multiple easy handles share data between them. Have them update +and use the \fBsame\fP cookie database or DNS cache! This way, each single +transfer will take advantage from data updates made by the other transfer(s). +.SH "SHARE OBJECT" +You create a shared object with \fIcurl_share_init(3)\fP. It returns a handle +for a newly created one. + +You tell the shared object what data you want it to share by using +\fIcurl_share_setopt(3)\fP. + +Since you can use this share from multiple threads, and libcurl has no +internal thread synchronization, you must provide mutex callbacks if you're +using this multi-threaded. You set lock and unlock functions with +\fIcurl_share_setopt(3)\fP too. + +Then, you make an easy handle to use this share, you set the +\fICURLOPT_SHARE\fP option with \fIcurl_easy_setopt(3)\fP, and pass in share +handle. You can make any number of easy handles share the same share handle. + +To make an easy handle stop using that particular share, you set +\fICURLOPT_SHARE\fP to NULL for that easy handle. To make a handle stop +sharing a particular data, you can \fICURLSHOPT_UNSHARE\fP it. + +When you're done using the share, make sure that no easy handle is still using +it, and call \fIcurl_share_cleanup(3)\fP on the handle. +.SH "SEE ALSO" +.BR curl_share_init "(3), " curl_share_setopt "(3), " curl_share_cleanup "(3)" |
