CURLOPT_SHARE(3) curl_easy_setopt options 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 unshare
an object that was using cookies (or change to another object that does
not share cookies), the easy handle will get its cookie engine dis-
abled.
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

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);
