2005-05-04 Neal H. Walfield <neal@gnu.org> * Makefile (SRCS): Add pt-thread_dealloc.c. * sysdeps/mach/pt-thread-dealloc.c: New file. * pthread/pt-internal.h (__pthread_thread_dealloc): New declaration. (__pthread_thread_halt): Add parameter NEED_DEALLOC. Update callers. * sysdeps/mach/pt-thread-halt.c (__pthread_thread_halt): Respect new NEED_DEALLOC parameter. Move code which deallocates kernel resources from here ... * sysdeps/mach/pt-thread-dealloc.c (__pthread_thread_dealloc): ...to here. * pthread/pt-create.c (__pthread_create_internal): Call __pthread_thread_dealloc on failure. * pthread/pt-exit.c (pthread_exit): Call __pthread_thread_dealloc. * sysdeps/mach/pt-thread-alloc.c (create_wakeupmsg): Call __mach_port_destroy to deallocate the receive right. __mach_port_deallocate won't do it. * pthread/pt-detach.c (pthread_detach): Don't call __pthread_thread_halt a second time. * sysdeps/mach/hurd/pt-sysdep.c (_cthread_init_routine): Fix declaration. (init_routine): Update declaration and remove gratuitous cast.
