CURLOPT_SHARE(3)                    libcurl                   CURLOPT_SHARE(3)

NAME
       CURLOPT_SHARE - 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 stop
       sharing an object that was using cookies (or change to another object
       that does not 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);
       }
