- avoid writing "set ..." or "enable/disable ..." or "specify ..." *All* options for curl_easy_setopt() are about setting or enabling things and most of the existing options didn't use that way of description. - start with lowercase letter, unless abbreviation. For consistency. - Some additional touch-ups Closes #7688

.SH NAME
|
|
CURLOPT_SHARE \- 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.
