( _PTHREAD_NEW, _PTHREAD_INUSE, _PTHREAD_EXITED, _PTHREAD_REUSE): Add. * create.c (pthread_create): Minor rename "us" to "new" (I need these cues but it doesn't stop me coming out with some major bugs at times). Load start_routine and arg into the thread so the wrapper can call it. * exit.c (pthread_exit): Fix pthread_this should be pthread_self. * cancel.c (pthread_setcancelstate): Change _pthread_threads_thread_t * to pthread_t and init with pthread_this().

Not complete. * implement.h (_pthread_threads_thread): Rename, remove thread member, add win32handle and ptstatus members.

1998-07-26Mon Jul 27 00:20:37 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj

1998-07-26Sun Jul 26 13:06:12 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* exit.c (_pthread_exit): New function. Called from pthread_exit() and _pthread_start_call() to exit the thread. It allows an extra argument which is the return code passed to _endthreadex(). * create.c (_pthread_start_call): Change pthread_exit() call to _pthread_exit() call.
1998-07-26Sun Jul 26 13:06:12 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* exit.c (_pthread_vacuum): Add thread entry deletion code moved from _pthread_start_call(). See next item. (pthread_exit): Remove longjmp(). Add mutex lock around thread table manipulation code.

1998-07-251998-07-26 Ben Elliston <bje@cygnus.com>bje

1998-07-251998-07-26 Ben Elliston <bje@cygnus.com>bje
* mutex.c (pthread_mutexattr_setpshared): Not supported; remove. (pthread_mutexattr_getpshared): Likewise. * pthread.h (pthread_mutexattr_setpshared): Remove prototype. (pthread_mutexattr_getpshared): Likewise.
1998-07-25Sun Jul 26 00:09:59 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* sync.c: Rename all instances of _pthread_count_mutex to _pthread_table_mutex. * implement.h: Rename _pthread_count_mutex to _pthread_table_mutex. * global.c: Rename _pthread_count_mutex to _pthread_table_mutex. * create.c (pthread_create): Add critical sections.

1998-07-25Sun Jul 26 00:09:59 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* cancel.c (pthread_setcancelstate): Fix indirection bug and rename "this" to "us".
1998-07-25Sun Jul 26 00:09:59 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* signal.c (pthread_sigmask): Rename "this" to "us" and fix some minor syntax errors. Declare "us" and initialise it. * sync.c (pthread_detach): Rename "this" to "target".
1998-07-25Sun Jul 26 00:09:59 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* pthread.h: Converting PTHREAD_* defines to alias the (const int) values in global.c. * global.c: Started converting PTHREAD_* defines to (const int) as a part of making the eventual pthreads DLL binary compatible through version changes.
1998-07-25Sun Jul 26 00:09:59 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj
* condvar.c (cond_wait): Add cancelation point. This applies the point to both pthread_cond_wait() and pthread_cond_timedwait(). * exit.c (pthread_exit): Rename "this" to "us". * implement.h: Add comment. * sync.c (pthread_join): I've satisfied myself that pthread_detach() does set the detached attribute in the thread entry attributes to PTHREAD_CREATE_DETACHED. "if" conditions were changed to test that attribute instead of a separate flag. * create.c (pthread_create): Rename "this" to "us". (pthread_create): cancelstate and canceltype are not attributes so the copy to thread entry attribute storage was removed. Only the thread itself can change it's cancelstate or canceltype, ie. the thread must exist already.
1998-07-25Sun Jul 26 00:09:59 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>rpj

(_pthread_find_thread_entry): Rename "this" to "entry". (_pthread_delete_thread_entry): Rename "thread_entry" to "entry". * create.c (_pthread_start_call): Mutexes changed to _pthread_count_mutex. All access to the threads table entries is under the one mutex. Otherwise chaos reigns. Sat Jul 25 23:16:51 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au> * implement.h (_pthread_threads_thread): Move cancelstate and canceltype members out of pthread_attr_t into here.
