SYNOPSIS
       #include <curl/curl.h>

       CURLM *curl_multi_init( );

DESCRIPTION
       This  function  returns  a  CURLM handle to be used as input to all the
       other multi-functions, sometimes referred to as a multi handle in  some
       places  in  the documentation. This init call MUST have a corresponding
       call to curl_multi_cleanup(3) when the operation is complete.

RETURN VALUE
       If this function returns NULL, something went wrong and you cannot  use
       the other curl functions.
