|
|
.SH NAME
|
|
curl_multi_timeout \- how long to wait for action before proceeding
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLMcode curl_multi_timeout(CURLM *multi_handle, long *timeout);
|
|
.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.
|
|
|
|
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
|
|
at all set.
|
|
.SH "RETURN VALUE"
|
|
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
|
|
by a previous call to \fBcurl_multi_socket(3)\fP.
|
|
.SH AVAILABILITY
|
|
This function was added in libcurl 7.15.4, although not deemed stable yet.
