.TH curl_multi_timeout 3 "2 Jan 2006" "libcurl 7.16.0" "libcurl Manual"
.SH NAME
curl_multi_timeout \- how long to wait for action before proceeding
.SH SYNOPSIS
#include <curl/curl.h>
long curl_multi_timeout(CURLM *multi_handle);
.SH DESCRIPTION
An application using the libcurl multi interface should call
\fBcurl_multi_timeout(3)\fP to figure out how long it should wait for socket
actions \- at most \- before proceeding.
Proceeding means either doing the socket-style timeout action: call the
\fBcurl_multi_socket(3)\fP function with the \fBsockfd\fP argument set to
CURL_SOCKET_TIMEOUT and the \fBeasy\fP argument set to CURL_EASY_TIMEOUT, or
simply calling \fBcurl_multi_perform(3)\fP if you're using the simpler and
older multi interface approach.
.SH "RETURN VALUE"
The timeout value in number of milliseconds. If 0, it means you should proceed
immediately without waiting for anything.
.SH "TYPICAL USAGE"
Call \fBcurl_multi_timeout(3)\fP, then wait for action on the sockets. You
figure out which sockets to wait for by calling \fBcurl_multi_fdset(3)\fP or
by a previous call to \fBcurl_multi_socket(3)\fP.
.SH AVAILABILITY
This function was added in libcurl 7.16.0
