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,
makes 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 uses
that cookie cache and get the cookie engine enabled. If you stop shar-
ing an object that was using cookies (or change to another object that
does not share cookies), the easy handle gets its cookie engine dis-
abled.
Data that the share object is not set to share is 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

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);
