curl_share_setopt(3) libcurl Manual curl_share_setopt(3)
NAME
curl_share_setopt - Set options for a shared object
SYNOPSIS
#include <curl/curl.h>
CURLSHcode curl_share_setopt(CURLSH *share, CURLSHoption option, parameter);
DESCRIPTION
Set the option to parameter for the given share.
OPTIONS
CURLSHOPT_LOCKFUNC
The parameter must be a pointer to a function matching the following prototype:
void lock_function(CURL *handle, curl_lock_data data, curl_lock_access access, void
*userptr);
data defines what data libcurl wants to lock, and you must make sure that only one
lock is given at any time for each kind of data.
access defines what access type libcurl wants, shared or single.
userptr is the pointer you set with CURLSHOPT_USERDATA.
CURLSHOPT_UNLOCKFUNC
The parameter must be a pointer to a function matching the following prototype:
void unlock_function(CURL *handle, curl_lock_data data, void *userptr);
data defines what data libcurl wants to unlock, and you must make sure that only
one lock is given at any time for each kind of data.
userptr is the pointer you set with CURLSHOPT_USERDATA.
CURLSHOPT_SHARE
The parameter specifies a type of data that should be shared. This may be set to
one of the values described below.
CURL_LOCK_DATA_COOKIE
Cookie data will be shared across the easy handles using this shared object.
CURL_LOCK_DATA_DNS
Cached DNS hosts will be shared across the easy handles using this shared
object. Note that when you use the multi interface, all easy handles added
to the same multi handle will share DNS cache by default without this having
to be used!
CURL_LOCK_DATA_SSL_SESSION
SSL session IDs will be shared across the easy handles using this shared
object. This will reduce the time spent in the SSL handshake when reconnect-
ing to the same server. Note SSL session IDs are reused within the same easy
handle by default.
CURLSHOPT_UNSHARE
This option does the opposite of CURLSHOPT_SHARE. It specifies that the specified
parameter will no longer be shared. Valid values are the same as those for CURL-
SHOPT_SHARE.
CURLSHOPT_USERDATA
The parameter allows you to specify a pointer to data that will be passed to the
lock_function and unlock_function each time it is called.
RETURN VALUE
CURLSHE_OK (zero) means that the option was set properly, non-zero means an error occurred
as <curl/curl.h> defines. See the libcurl-errors.3 man page for the full list with
descriptions.
