|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLMcode curl_multi_fdset(CURLM *multi_handle,
|
|
fd_set *read_fd_set,
|
|

.SH 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.
|
|
.SH RETURN VALUE
|
|
CURLMcode type, general libcurl multi interface error code. See
|
|
\fIlibcurl-errors.3\fP
