From c0239a0b8b5efaa5b0666e778f61f5cd402c0526 Mon Sep 17 00:00:00 2001 From: "Richard M. Stallman" Date: Thu, 1 Feb 1996 20:35:59 +0000 Subject: [PATCH] (wait_reading_process_input): If select times out, return only if we had no timers to shorten the wait. Don't shorten the wait for timers if time_limit is -1. --- src/process.c | 15 +++++++++++---- 1 file changed, 11 insertions(+), 4 deletions(-) diff --git a/src/process.c b/src/process.c index 59bcd8cb11d..7af4115de6f 100644 --- a/src/process.c +++ b/src/process.c @@ -2026,6 +2026,8 @@ wait_reading_process_input (time_limit, microsecs, read_kbd, do_display) while (1) { + int timeout_reduced_for_timers = 0; + /* If calling from keyboard input, do not quit since we want to return C-g as an input character.
