1998-07-18 Ben Elliston * condvar.c (pthread_condattr_init): Do not attempt to malloc any storage; none is needed now that condattr_t is an empty struct. (pthread_condattr_destory): Likewise; do not free storage. (pthread_condattr_setpshared): No longer supported; return ENOSYS. (pthread_condattr_getpshared): Likewise. (pthread_cond_init): Implement with help from Douglas Schmidt. Remember to initialise the cv's internal mutex. (pthread_cond_wait): Likewise. (pthread_cond_signal): Likewise. (pthread_cond_broadcast): Likewise. (pthread_cond_timedwait): Preliminary implementation, but I need to see some API documentation for `WaitForMultipleObject'. (pthread_destory): Implement. * pthread.h (pthread_cond_init): Add function protoype. (pthread_cond_broadcast): Likewise. (pthread_cond_signal): Likewise. (pthread_cond_timedwait): Likewise. (pthread_cond_wait): Likewise. (pthread_cond_destroy): Likewise. (pthread_cond_t): Define this type. Fix for u_int. Do not assume that the mutex contained withing the pthread_cond_t structure will be a critical section. Use our new POSIX type! * implement.h (_pthread_condattr_t): Remove shared attribute. 1998-07-17 Ben Elliston * 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 * 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 * 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 * 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. (pthread_lock): Likewise. (pthread_trylock): Likewise. (pthread_unlock): Likewise. (pthread_condattr_init): Likewise. (pthread_condattr_destroy): Likewise. (pthread_condattr_setpshared): Likewise. (pthread_condattr_getpshared): Likewise. * mutex.c (pthread_mutex_init): Implement. (pthread_mutex_destroy): Likewise. (pthread_lock): Likewise. (pthread_trylock): Likewise. (pthread_unlock): Likewise. 1998-07-12 Ben Elliston * 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_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 * implement.h: Preliminary implementation specific defines. * create.c (pthread_create): Preliminary implementation. 1998-07-11 Ben Elliston * 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 * misc.c (pthread_self): Implement. * exit.c (pthread_exit): Implement. * pthread.h (pthread_exit): Add function prototype.
