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);
}
