NAME
       curl_multi_timeout - how long to wait for action before proceeding

SYNOPSIS
       #include <curl/curl.h>

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

DESCRIPTION
       An application using the libcurl multi interface should call curl_multi_timeout(3) 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 curl_multi_socket_action(3) function with the sockfd  argument  set
       to CURL_SOCKET_TIMEOUT, or call curl_multi_perform(3) if you're using the simpler and older multi interface approach.

       The  timeout value returned in the long timeout points to, is in number of milliseconds at this very moment. If 0, it means you should pro-
       ceed immediately without waiting for anything. If it returns -1, there's no timeout at all set.

       An application that uses the multi_socket API SHOULD not use this function, but SHOULD  instead	use  curl_multi_setopt(3)  and	its  CURL-
       MOPT_TIMERFUNCTION option for proper and desired behavior.

       Note:  if  libcurl  returns a -1 timeout here, it just means that libcurl currently has no stored timeout value. You must not wait too long
       (more than a few seconds perhaps) before you call curl_multi_perform() again.

RETURN VALUE
       The standard CURLMcode for multi interface error codes.

TYPICAL USAGE
       Call curl_multi_timeout(3), then wait for action on the sockets. You figure out which sockets to wait for by calling curl_multi_fdset(3) or
       by a previous call to curl_multi_socket(3).

AVAILABILITY
       This function was added in libcurl 7.15.4.
