       Calling pthread_testcancel() creates a cancelation point within the calling thread, so that a thread that
       is otherwise executing code that contains no cancelation points will respond to a cancelation request.

       If  cancelability  is  disabled  (using pthread_setcancelstate(3)), or no cancelation request is pending,
       then a call to pthread_testcancel() has no effect.

       This function always succeeds.

       See pthread_cleanup_push(3).

       This function does not return a value.  If the calling thread is canceled as a consequence of a  call  to
       this function, then the function does not return.
