1998-07-17 Ben Elliston <bje@cygnus.com>
* pthread.h (PTHREADS_PROCESS_PRIVATE): Remove.
(PTHREAD_PROCESS_SHARED): Likewise. No support for mutexes shared
across processes for now.
(pthread_mutex_t): Use a Win32 CRITICAL_SECTION type for better
performance.
* implement.h (_pthread_mutexattr_t): Remove shared attribute.
* mutex.c (pthread_mutexattr_setpshared): This optional function
is no longer supported, since we want to implement POSIX mutex
variables using the much more efficient Win32 critical section
primitives. Critical section objects in Win32 cannot be shared
between processes.
(pthread_mutexattr_getpshared): Likewise.
(pthread_mutexattr_init): No need to malloc any storage; the
attributes structure is now empty.
(pthread_mutexattr_destroy): This is now a nop.
(pthread_mutex_init): Use InitializeCriticalSection().
(pthread_mutex_destroy): Use DeleteCriticalSection().
(pthread_mutex_lock): Use EnterCriticalSection().
(pthread_mutex_trylock): Use TryEnterCriticalSection(). This is
not supported by Windows 9x, but trylock is a hack anyway, IMHO.
(pthread_mutex_unlock): Use LeaveCriticalSection().
1998-07-14 Ben Elliston <bje@cygnus.com>
* attr.c (pthread_attr_setstacksize): Implement.
(pthread_attr_getstacksize): Likewise.
(pthread_attr_setstackaddr): Likewise.
(pthread_attr_getstackaddr): Likewise.
(pthread_attr_init): Likewise.
(pthread_attr_destroy): Likewise.
* condvar.c (pthread_condattr_init): Add `_cond' to function name.
* mutex.c (pthread_mutex_lock): Add `_mutex' to function name.
(pthread_mutex_trylock): Likewise.
(pthread_mutex_unlock): Likewise.
* pthread.h (pthread_condattr_setpshared): Fix typo.
(pthread_attr_init): Add function prototype.
(pthread_attr_destroy): Likewise.
(pthread_attr_setstacksize): Likewise.
(pthread_attr_getstacksize): Likewise.
(pthread_attr_setstackaddr): Likewise.
(pthread_attr_getstackaddr): Likewise.
Mon Jul 13 01:09:55 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>
* implement.h: Wrap in #ifndef _IMPLEMENT_H
* create.c (pthread_create): Map stacksize attr to Win32.
* mutex.c: Include implement.h
1998-07-13 Ben Elliston <bje@cygnus.com>
* condvar.c (pthread_condattr_init): Implement.
(pthread_condattr_destroy): Likewise.
(pthread_condattr_setpshared): Likewise.
(pthread_condattr_getpshared): Likewise.
* implement.h (PTHREAD_THREADS_MAX): Remove trailing semicolon.
(PTHREAD_STACK_MIN): Specify; needs confirming.
(_pthread_attr_t): Define this type.
(_pthread_condattr_t): Likewise.
* pthread.h (pthread_mutex_t): Define this type.
(pthread_condattr_t): Likewise.
(pthread_mutex_destroy): Add function prototype.

* mutex.c (pthread_mutex_init): Implement.
(pthread_mutex_destroy): Likewise.
(pthread_lock): Likewise.
(pthread_trylock): Likewise.
(pthread_unlock): Likewise.
1998-07-12 Ben Elliston <bje@cygnus.com>
* implement.h (_pthread_mutexattr_t): Define this implementation
internal type. Application programmers only see a mutex attribute
object as a void pointer.
* pthread.h (pthread_mutexattr_t): Define this type.
(pthread_mutexattr_init): Add function prototype.
(pthread_mutexattr_destroy): Likewise.
(pthread_mutexattr_setpshared): Likewise.
(pthread_mutexattr_getpshared): Likewise.
(pthread_mutexattr_setprotocol): Likewise.
(pthread_mutexattr_getprotocol): Likewise.
(pthread_mutexattr_setprioceiling): Likewise.
(pthread_mutexattr_getprioceiling): Likewise.
(PTHREAD_PROCESS_PRIVATE): Define.
(PTHREAD_PROCESS_SHARED): Define.
* mutex.c (pthread_mutexattr_init): Implement.
(pthread_mutexattr_destroy): Implement.

(pthread_mutexattr_getprotocol): Likewise.
(pthread_mutexattr_setprioceiling): Likewise.
(pthread_mutexattr_getprioceiling): Likewise.
(pthread_mutexattr_setpshared): Likewise.
(pthread_mutexattr_getpshared): Likewise.
(insert_attr): New function; very preliminary implementation!
(is_attr): Likewise.
(remove_attr): Likewise.
Sat Jul 11 14:48:54 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>
* implement.h: Preliminary implementation specific defines.
* create.c (pthread_create): Preliminary implementation.
1998-07-11 Ben Elliston <bje@cygnus.com>
* sync.c (pthread_join): Implement.
* misc.c (pthread_equal): Likewise.
* pthread.h (pthread_join): Add function prototype.
(pthread_equal): Likewise.
1998-07-10 Ben Elliston <bje@cygnus.com>
* misc.c (pthread_self): Implement.
* exit.c (pthread_exit): Implement.
* pthread.h (pthread_exit): Add function prototype.
(pthread_self): Likewise.
(pthread_t): Define this type.
1998-07-09 Ben Elliston <bje@cygnus.com>
* create.c (pthread_create): A dummy stub right now.
* pthread.h (pthread_create): Add function prototype.
