curl_multi_fdset(3)	 libcurl Manual	      curl_multi_fdset(3)

     curl_multi_fdset - extracts file descriptor information from
     a multi handle

     #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);

     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,	but  be	 sure  to
     FD_ZERO	them	before	  calling    this   function   as
     curl_multi_fdset(3) only adds its own descriptors it doesn't
     zero     or     otherwise	   remove    any    other.    The
     curl_multi_perform(3) function should be called as	 soon  as
     one of them are ready to be read from or written to.

     If no file descriptors are set by libcurl, max_fd will  con-
     tain  -1  when this function returns. Otherwise it will con-
     tain the higher descriptor number libcurl set.

     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 other-
     wise libcurl-internal retries and timeouts may not	 work  as
     you'd think and want.

     CURLMcode type, general libcurl multi interface error  code.
