# NAME
curl_share_init - Create a shared object
# SYNOPSIS
~~~c
#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 handle in
some places in the documentation. This init call MUST have a corresponding
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.
# EXAMPLE
~~~c
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 7.10
# RETURN VALUE
If this function returns NULL, something went wrong (out of memory, etc.)
and therefore the share object was not created.
