NAME
       curl_multi_fdset - add an easy handle to a multi session

SYNOPSIS
       #include <curl/curl.h>

       CURLMcode curl_multi_fdset(CURLM *multi_handle,
				  fd_set *read_fd_set,
				  fd_set *write_fd_set,
				  fd_set *exc_fd_set,
				  int *max_fd);

DESCRIPTION
       This  function  extracts  file  descriptor information from a given multi_handle.  libcurl returns its fd_set sets. The application can use
       these to select() or poll() on. The curl_multi_perform() function should be called as soon as one of them are ready  to	be  read  from	or
       written to.

       NOTE  that  once  this call is made, you must not remove the sets you point to, as libcurl will need to be able to read them. It needs them
       after select() calls, to know if certain sockets are readable or writable.

RETURN VALUE
       CURLMcode type, general libcurl multi interface error code.
