* attr.c (pthread_setstacksize): Update test of attr argument. (pthread_getstacksize): Likewise. (pthread_setstackaddr): Likewise. (pthread_getstackaddr): Likewise. (pthread_attr_init): No need to allocate any storage. (pthread_attr_destroy): No need to free any storage. * mutex.c (is_attr): Not likely to be needed; remove. (remove_attr): Likewise. (insert_attr): Likewise. * pthread.h (pthread_attr_t): Moved here from implement.h. * implement.h (_pthread_mutexattr_t): Moved to a public definition in pthread.h. There was little gain in hiding these details. (_pthread_condattr_t): Likewise.

* pthread.h (pthread_atfork): Add function prototype. * fork.c (pthread_atfork): Preliminary implementation. (_pthread_fork): Likewise.

* exit2.c (main): Fix size of pthread_t array.

* cleanup.c (_pthread_cleanup_push): Implement. (_pthread_cleanup_pop): Implement. (_pthread_do_cancellation): Implement. These are private to the implementation. The real cleanup functions are macros. See below. * pthread.h (pthread_cleanup_push): Implement as a macro. (pthread_cleanup_pop): Implement as a macro. Because these are macros which start and end a block, the POSIX scoping requirement is observed. See the comment in the file. * exit.c (pthread_exit): Refine the code. * create.c (pthread_create): Code cleanup. * implement.h (RND_SIZEOF): Add RND_SIZEOF(T) to round sizeof(T) up to multiple of DWORD. Add function prototypes. * private.c (_pthread_getthreadindex): "*thread" should have been "thread". Detect empty slot fail condition.

* misc.c (pthread_once): Don't use a per-application flag and mutex--make `pthread_once_t' contain these elements in their structure. The earlier version had incorrect semantics.
1998-07-201998-07-20 Ben Elliston <bje@cygnus.com>bje
* pthread.h (_pthread_once_flag): Remove. (_pthread_once_lock): Remove. (pthread_once): Add function prototype. (pthread_once_t): Define this type.

1998-07-191998-07-20 Ben Elliston <bje@cygnus.com>bje
* pthread.h (_pthread_once_flag): Add new variable. (_pthread_once_lock): Add new mutex lock to ensure integrity of access to _pthread_once_flag.

* private.c (_pthread_getthreadindex): Implement.
1998-07-19Mon Jul 20 02:31:05 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* private.c (_pthread_getthreadindex): Implement. * pthread.h: Add application static data dependent on _PTHREADS_BUILD_DLL define. This is needed to avoid allocating non-sharable static data within the pthread DLL. * implement.h: Add _pthread_cleanup_stack_t, _pthread_cleanup_node_t and _PTHREAD_HASH_INDEX. * exit.c (pthread_exit): Begin work on cleanup and de-allocate thread-private storage. * create.c (pthread_create): Add thread to thread table. Keep a thread-private copy of the attributes with default values filled in when necessary. Same for the cleanup stack. Make pthread_create C run-time library friendly by using _beginthreadex() instead of CreateThread(). Fix error returns. Sun Jul 19 16:26:23 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * implement.h: Rename pthreads_thread_count to _pthread_threads_count. Create _pthread_threads_thread_t struct to keep thread specific data. * create.c: Rename pthreads_thread_count to _pthread_threads_count. (pthread_create): Handle errors from CreateThread().

* condvar.c (pthread_cond_wait): Generalise. Moved from here .. (cond_wait): To here. (pthread_cond_timedwait): Implement; use generalised cond_wait().

* 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.
1998-07-171998-07-18 Ben Elliston <bje@cygnus.com>bje
* pthread.h (pthread_cond_t): 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!
1998-07-171998-07-18 Ben Elliston <bje@cygnus.com>bje

1998-07-171998-07-17 Ben Elliston <bje@cygnus.com>bje
* mutex.c (pthread_mutex_init): Use InitializeCritcalSection(). (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().
1998-07-171998-07-17 Ben Elliston <bje@cygnus.com>bje
* 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.
1998-07-171998-07-17 Ben Elliston <bje@cygnus.com>bje
* mutex.c (pthread_mutexattr_init): No need to malloc any storage; the attributes structure is now empty. (pthread_mutexattr_destroy): This is now a nop.

1998-07-171998-07-17 Ben Elliston <bje@cygnus.com>bje
* 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.
