From 7ac5b8e2fae145766821d141cf892bbfa50d6618 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 16 May 2003 22:09:32 +0000 Subject: [PATCH] Update. * pthread_join.c (pthread_join): Set tid field of the joined thread to -1. This isn't necessary but helps to recognize some error conditions with almost no cost. * allocatestack.c (FREE_P): Also negative values indicate an unused stack. --- nptl/ChangeLog | 7 +++++++ nptl/allocatestack.c | 2 +- nptl/pthread_join.c | 3 +++ 3 files changed, 11 insertions(+), 1 deletion(-) diff --git a/nptl/ChangeLog b/nptl/ChangeLog index e63c71c841..60b03f764d 100644 --- a/nptl/ChangeLog +++ b/nptl/ChangeLog @@ -1,5 +1,12 @@ 2003-05-16 Ulrich Drepper + * pthread_join.c (pthread_join): Set tid field of the joined + thread to -1.
