curl_share_init(3) Library Functions Manual curl_share_init(3)
NAME
curl_share_init - create a share object
SYNOPSIS
#include <curl/curl.h>
CURLSH *curl_share_init();
DESCRIPTION
This function returns a pointer to a CURLSH handle to be used as input
to all the other share-functions, sometimes referred to as a share han-
dle in some places in the documentation. This init call MUST have a cor-
responding call to curl_share_cleanup(3) when all operations using the
share are complete.
This share handle is what you pass to curl using the CURLOPT_SHARE(3)
option with curl_easy_setopt(3), to make that specific curl handle use
the data in this share.
PROTOCOLS
This functionality affects all supported protocols
EXAMPLE
int main(void)
{
CURLSHcode sh;
CURLSH *share = curl_share_init();
sh = curl_share_setopt(share, CURLSHOPT_SHARE, CURL_LOCK_DATA_CONNECT);
if(sh)
printf("Error: %s\n", curl_share_strerror(sh));
}
AVAILABILITY
Added in curl 7.10
RETURN VALUE
If this function returns NULL, something went wrong (out of memory,
etc.) and therefore the share object was not created.
