From 29bf0598aad58d9da5dd8c5358f5175dae49026d Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Mon, 3 Jun 2013 20:19:51 +0200 Subject: curl_multi_wait: reduce timeout if the multi handle wants to If the multi handle's pending timeout is less than what is passed into this function, it will now opt to use the shorter time anyway since it is a very good hint that the handle wants to process something in a shorter time than what otherwise would happen. curl_multi_wait.3 was updated accordingly to clarify This is the reason for bug #1224 Bug: http://curl.haxx.se/bug/view.cgi?id=1224 Reported-by: Andrii Moiseiev --- docs/libcurl/curl_multi_wait.3 | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'docs/libcurl') diff --git a/docs/libcurl/curl_multi_wait.3 b/docs/libcurl/curl_multi_wait.3 index b14760bf3..c266f2569 100644 --- a/docs/libcurl/curl_multi_wait.3 +++ b/docs/libcurl/curl_multi_wait.3 @@ -5,7 +5,7 @@ .\" * | (__| |_| | _ <| |___ .\" * \___|\___/|_| \_\_____| .\" * -.\" * Copyright (C) 1998 - 2012, Daniel Stenberg, , et al. +.\" * Copyright (C) 1998 - 2013, Daniel Stenberg, , et al. .\" * .\" * This software is licensed as described in the file COPYING, which .\" * you should have received as part of this distribution.
