From 97cb4b33462735b93ac9522df6bf4d43d0b7fe71 Mon Sep 17 00:00:00 2001 From: bje Date: Sun, 4 Oct 1998 18:32:15 +0000 Subject: 1998-10-05 Ben Elliston * global.c (PTHREAD_MUTEX_INITIALIZER): Move to pthread.h. * pthread.h (PTHREAD_MUTEX_INITIALIZER): Define. (pthread_mutex_t): Reimplement as a struct containing a valid flag. If the flag is ever down upon entry to a mutex operation, we call pthread_mutex_create() to initialise the object. This fixes the problem of how to handle statically initialised objects that can't call InitializeCriticalSection() due to their context. * mutex.c (pthread_mutex_init): Set valid flag. (pthread_mutex_destroy): Clear valid flag. (pthread_mutex_lock): Check and handle the valid flag. (pthread_mutex_unlock): Likewise. (pthread_mutex_trylock): Likewise. * tests/mutex3.c: New file; test for the static initialisation macro. Passes. --- ChangeLog | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index cbabbdf..5934633 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,23 @@ +1998-10-05 Ben Elliston + + * global.c (PTHREAD_MUTEX_INITIALIZER): Move to pthread.h. + + * pthread.h (PTHREAD_MUTEX_INITIALIZER): Define. + (pthread_mutex_t): Reimplement as a struct containing a valid + flag.
