From 75f8ad67d45d48b9cdde5a298083881790c76c73 Mon Sep 17 00:00:00 2001 From: rpj Date: Thu, 31 Jan 2002 06:56:03 +0000 Subject: 2002-01-27 Ross Johnson * mutex.c (pthread_mutex_timedlock): New function suggested by Alexander Terekhov. The logic required to implement this properly came from Alexander, with some collaboration with Thomas Pfaff. (pthread_mutex_unlock): Wrap the waiters check and sema post in a critical section to prevent a race with pthread_mutex_timedlock. (ptw32_timed_semwait): New function; returns a special result if the absolute timeout parameter represents a time already passed when called; used by pthread_mutex_timedwait(). Have deliberately not reused the name "ptw32_sem_timedwait" because they are not the same routine. * condvar.c (ptw32_cond_timedwait): Use the new sem_timedwait() instead of ptw32_sem_timedwait(), which now has a different function. See previous. * implement.h: Remove prototype for ptw32_sem_timedwait. See next. (pthread_mutex_t_): Add critical section element for access to lock_idx during mutex post-timeout processing. * semaphore.h (sem_timedwait): See next. * semaphore.c (sem_timedwait): See next. * private.c (ptw32_sem_timedwait): Move to semaphore.c and rename as sem_timedwait(). 2002-01-18 Ross Johnson * sync.c (pthread_join): Was getting the exit code from the calling thread rather than the joined thread if defined(__MINGW32__) && !defined(__MSVCRT__). 2002-01-15 Ross Johnson * pthread.h: Unless the build explicitly defines __CLEANUP_SEH, __CLEANUP_CXX, or __CLEANUP_C, then the build defaults to __CLEANUP_C style cleanup. This style uses setjmp/longjmp in the cancelation and thread exit implementations and therefore won't do stack unwinding if linked to applications that have it (e.g. C++ apps). This is currently consistent with most/all commercial Unix POSIX threads implementations. * spin.c (pthread_spin_init): Edit renamed function call. * nonportable.c (pthread_num_processors_np): New. (pthread_getprocessors_np): Renamed to ptw32_getprocessors and moved to private.c. * private.c (pthread_getprocessors): Moved here from nonportable.c. * pthread.def (pthread_getprocessors_np): Removed from export list. * rwlock.c (pthread_rwlockattr_init): New. (pthread_rwlockattr_destroy): New. (pthread_rwlockattr_getpshared): New. (pthread_rwlockattr_setpshared): New. --- misc.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'misc.c') diff --git a/misc.c b/misc.c index 57685bf..0fbff03 100644 --- a/misc.c +++ b/misc.c @@ -333,7 +333,7 @@ ptw32_cancelable_wait (HANDLE waitHandle, DWORD timeout) else { /* - * Either got the mutex or the cancel event + * Either got the handle or the cancel event * was signaled */ switch (status - WAIT_OBJECT_0) @@ -341,7 +341,7 @@ ptw32_cancelable_wait (HANDLE waitHandle, DWORD timeout) case 0: /* - * Got the mutex + * Got the handle */ result = 0; break; -- cgit v1.2.3
