CURLOPT_SHARE(3)					     curl_easy_setopt options						  CURLOPT_SHARE(3)

NAME

       CURLOPT_SHARE - specify share handle to use

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SHARE, CURLSH *share);

DESCRIPTION

       Pass  a share handle as a parameter. The share handle must have been created by a previous call to curl_share_init(3). 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 MUST use the locking methods in the share handle. See
       curl_share_setopt(3) 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.

       Set this option to NULL again to stop using that share object.

       NULL

NAME

       libcurl-share - how to use the share interface

DESCRIPTION

       This  is an overview on how to use the libcurl share interface in your C programs. There are specific man pages for each function mentioned
       in here.

       All functions in the share interface are prefixed with curl_share.

OBJECTIVES

       The share interface was added to enable sharing of data between curl "handles".

ONE SET OF DATA - MANY TRANSFERS
       You can have multiple easy handles share data between them. Have them update and use the same cookie database or DNS cache! This way,  each
       single transfer will take advantage from data updates made by the other transfer(s).

SHARE OBJECT

       You create a shared object with curl_share_init(3). It returns a handle for a newly created one.

       You tell the shared object what data you want it to share by using curl_share_setopt(3).

       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 curl_share_setopt(3) too.

       Then, you make an easy handle to use this share, you set the CURLOPT_SHARE option with curl_easy_setopt(3), 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 CURLOPT_SHARE to NULL for that easy handle. To make a handle stop sharing
       a particular data, you can CURLSHOPT_UNSHARE it.

       When you're done using the share, make sure that no easy handle is still using it, and call curl_share_cleanup(3) on the handle.
