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.
