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 _share_init&section=3">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
       _share_setopt&section=3">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.

DEFAULT
       NULL

PROTOCOLS
       All

EXAMPLE
       CURL *curl = curl_easy_init();
       CURL *curl2 = curl_easy_init(); /* a second handle */
       if(curl) {
         CURLSH *shobject = curl_share_init();
         curl_share_setopt(shobject, CURLSHOPT_SHARE, CURL_LOCK_DATA_COOKIE);

         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
         curl_easy_setopt(curl, CURLOPT_COOKIEFILE, "");
         curl_easy_setopt(curl, CURLOPT_SHARE, shobject);
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);

         /* the second handle shares cookies from the first */
         curl_easy_setopt(curl2, CURLOPT_URL, "https://example.com/second");
         curl_easy_setopt(curl2, CURLOPT_COOKIEFILE, "");
         curl_easy_setopt(curl2, CURLOPT_SHARE, shobject);
         ret = curl_easy_perform(curl2);
         curl_easy_cleanup(curl2);

         curl_share_cleanup(shobject);
       }
