# NAME
|
||
|
|
|
||
|
|
CURLOPT_SHARE - share handle to use
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#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,
|
||
|
|
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 **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 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.
