1999-11-02 Ulrich Drepper <drepper@cygnus.com>
* Makefile (libpthread-routines): Add events.
* events.c: New file.
* internals.h: Protect against multiple inclusion.
Include thread_dbP.h header.
(struct _pthread_descr_struct): Add new fields p_report_events and
p_eventbuf.
Declare event reporting functions.
* join.c (pthread_exit): Signal event if this is wanted.
* manager.c (__pthread_threads_events): New variable.
(pthread_handle_create): Take new parameters with event information.
Signal TD_CREATE event if wanted.
(__pthread_manager): Adjust pthread_handle_create call.
(pthread_start_thread_event): New function. Block until manager is
finished and then call pthread_start_thread.
(pthread_exited): Signal TD_REAP event if wanted.
1999-10-26 Ulrich Drepper <drepper@cygnus.com>
* restart.h (suspend_with_cancellation): Rewrite as a macro.
