From 0749394433f301cccd22d280cee1dd760b72e876 Mon Sep 17 00:00:00 2001 From: rpj Date: Mon, 28 Dec 1998 23:01:00 +0000 Subject: With this update I'm able to build the library and build and run the tsd1.c test successfully using buildlib.bat and build.bat scripts. I not convinced that I understand the relationships between "__cplusplus" and "_WIN32" and the MS compiler, particularly in pthread.h where pthread_cleanup_push etc is defined. In particular, I have assumed that the __try/__finally blocks are only available if _WIN32 and __cplusplus are defined. I suspect this is wrong. Tue Dec 29 13:11:16 1998 Ross Johnson * implement.h: Move the following struct definitions to pthread.h: pthread_t_, pthread_attr_t_, pthread_mutex_t_, pthread_mutex_t_, pthread_mutexattr_t_, pthread_key_t_, pthread_cond_t_, pthread_condattr_t_, pthread_once_t_. * pthread.h: Add "_" prefix to pthread_push_cleanup and pthread_pop_cleanup internal routines, and associated struct and typedefs. * buildlib.bat: Add compile command for semaphore.c * pthread.def: Comment out pthread_atfork routine name. Now unimplemented. * tsd.c (pthread_setspecific): Rename tkAssocCreate to _pthread_tkAssocCreate. (pthread_key_delete): Rename tkAssocDestroy to _pthread_tkAssocDestroy. * sync.c (pthread_join): Rename threadDestroy to _pthread_threadDestroy * sched.c (is_attr): attr is now **attr (was *attr), so add extra NULL pointer test. (pthread_attr_setschedparam): Increase redirection for attr which is now a **. (pthread_attr_getschedparam): Ditto. (pthread_setschedparam): Change thread validation and rename "thread" Win32 thread Handle element name to match John Bossom's version. (pthread_getschedparam): Ditto. * private.c (_pthread_threadDestroy): Rename call to callUserDestroyRoutines() as _pthread_callUserDestroyRoutines() * misc.c: Add #include "implement.h". * dll.c: Remove defined(KLUDGE) wrapped code. * fork.c: Remove redefinition of ENOMEM. Remove pthread_atfork() and fork() with #if 0/#endif. * create.c (pthread_create): Rename threadStart and threadDestroy calls to _pthread_threadStart and _pthread_threadDestroy. * implement.h: Rename "detachedstate" to "detachstate". * attr.c: Rename "detachedstate" to "detachstate". Mon Dec 28 09:54:39 1998 Ross Johnson * pthread.h (pthread_attr_t_): Change to *pthread_attr_t. * attr.c (pthread_attr_setstacksize): Merge with John Bossom's version. (pthread_attr_getstacksize): Merge with John Bossom's version. (pthread_attr_setstackaddr): Merge with John Bossom's version. (pthread_attr_getstackaddr): Merge with John Bossom's version. (pthread_attr_init): Merge with John Bossom's version. (pthread_attr_destroy): Merge with John Bossom's version. (pthread_attr_getdetachstate): Merge with John Bossom's version. (pthread_attr_setdetachstate): Merge with John Bossom's version. (is_attr): attr is now **attr (was *attr), so add extra NULL pointer test. * implement.h (pthread_attr_t_): Add and rename elements in JEB's version to correspond to original, so that it can be used with original attr routines. * pthread.h: Add #endif at end which was truncated in merging. --- semaphore.h | 65 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 65 insertions(+) create mode 100644 semaphore.h (limited to 'semaphore.h') diff --git a/semaphore.h b/semaphore.h new file mode 100644 index 0000000..7b9d352 --- /dev/null +++ b/semaphore.h @@ -0,0 +1,65 @@ +/* + * ------------------------------------------------------------- + * + * $Header: /cvs/pthreads-win32/pthreads/semaphore.h,v 1.1.2.1 1998/12/28 23:01:15 rpj Exp $ + * + * Module: semaphore.h + * + * Purpose: + * Semaphores aren't actually part of the PThreads standard. + * They are defined by the POSIX Standard: + * + * POSIX 1003.1b-1993 (POSIX.1b) + * + * They are supposed to follow the older UNIX convention for + * reporting errors.
