.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.
