curl_multi_fdset(3)             libcurl Manual             curl_multi_fdset(3)



NAME
       curl_multi_fdset - extracts file descriptor information from a multi handle

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() on.  The
       curl_multi_perform(3) function should be called as soon as one of them are ready to
       be read from or written to.

       You should also be aware that when doing select(),  you  should  consider  using  a
       rather  small  (single-digit number of seconds) timeout and call curl_multi_perform
       regularly - even if no activity has  been  seen  on  the  fd_sets  -  as  otherwise
       libcurl-internal retries and timeouts may not work as you’d think.

RETURN VALUE
       CURLMcode type, general libcurl multi interface error code. See libcurl-errors(3)

SEE ALSO
       curl_multi_cleanup(3),curl_multi_init(3)
