If the function is called when there is no \fIcurl_multi_poll(3)\fP call, it will cause the next call to return immediately. Calling this function only guarantees to wake up the current (or the next if there is no current) \fIcurl_multi_poll(3)\fP call, which means it is possible that multiple calls to this function will wake up the same waiting operation. This function has no effect on \fIcurl_multi_wait(3)\fP calls. .SH RETURN VALUE CURLMcode type, general libcurl multi interface error code. .SH "SEE ALSO" .BR curl_multi_poll "(3), " curl_multi_wait "(3)"
