| .SH NAME |
| curl_multi_fdset - extracts file descriptor information from a multi handle |
| .SH 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); |
| .ad |
| .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. |
| .SH "SEE ALSO" |
| .BR curl_multi_cleanup "(3)," curl_multi_init "(3)" |
