.SH NAME
CURLOPT_SHARE \- share handle to use
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SHARE, CURLSH *share);
.fi
.SH DESCRIPTION
Pass a \fIshare\fP handle as a parameter. The share handle must have been
created by a previous call to \fIcurl_share_init(3)\fP. 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 \fBMUST\fP use
the locking methods in the share handle. See \fIcurl_share_setopt(3)\fP 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 sharing an object
that was using cookies (or change to another object that does not share
cookies), the easy handle gets its cookie engine disabled.

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.
.SH DEFAULT
NULL
.SH PROTOCOLS
This functionality affects all supported protocols
.SH EXAMPLE
.nf
int main(void)
{
  CURL *curl = curl_easy_init();
  CURL *curl2 = curl_easy_init(); /* a second handle */
  if(curl) {
    CURLcode res;
    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);
    res = 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);
    res = curl_easy_perform(curl2);
    curl_easy_cleanup(curl2);
