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.
