+.TH CURLOPT_SHARE 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
+.SH NAME
+CURLOPT_SHARE \- specify share handle to use
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SHARE, CURLSH *share);
+.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,
+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
+\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 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 doesn't 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.

+NULL
