pthread_cancel

The following programs demonstrate how one thread can cancel (terminate) another using the library call pthread_cancel.

The first program, pthread_cancel.c uses pthread_cancel to cancel a thread at a function that libc designates as a cancellation point (here, either printf or sleep).

      The second program, pthread_testcancel.c demonstrates a thread
      that calls
      pthread_testcancel
      to create a cancellation point in a function that otherwise would not have one.

      The final program, pthread_cleanup.c demonstrates the use
      of
      pthread_cleanup_push
      and
      pthread_cleanup_pop
      to install a cleanup function that is called upon thread termination.
