.SH SYNOPSIS

#include <curl/curl.h>

long curl_multi_timeout(CURLM *multi_handle);

CURLMcode curl_multi_timeout(CURLM *multi_handle, long *timeout);

.SH DESCRIPTION

An application using the libcurl multi interface should call

simply calling \fBcurl_multi_perform(3)\fP if you're using the simpler and

older multi interface approach.

The timeout value returned in the long \fBtimeout\fP points to, is in number

of milliseconds at this very moment. If 0, it means you should proceed

immediately without waiting for anything. If it returns -1, there's no timeout

.SH "RETURN VALUE"

The timeout value in number of milliseconds. If 0, it means you should proceed

immediately without waiting for anything.

The standard CURLMcode for multi interface error codes.

.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
