2003-07-07 Ulrich Drepper <drepper@redhat.com> * descr.h (struct pthread): Add pid field. * allocatestack.c (allocate_stack): Initialize pid field in descriptor. (__reclaim_stacks): Likewise. * init.c (sigcancel_handler): If __ASSUME_CORRECT_SI_PID is defined also check for PID of the signal source. (__pthread_initialize_minimal_internal): Also initialize pid field of initial thread's descriptor. * pthread_cancel.c: Use tgkill instead of tkill if possible. * sysdeps/unix/sysv/linux/fork.c: Likewise. * sysdeps/unix/sysv/linux/pt-raise.c: Likewise. * sysdeps/unix/sysv/linux/pthread_kill.c: Likewise. * sysdeps/unix/sysv/linux/raise.c: Likewise.
