Compile and link with -pthread.
Calling pthread_testcancel() creates a cancellation point within the
calling thread, so that a thread that is otherwise executing code that
contains no cancellation points will respond to a cancellation request.
If cancelability is disabled (using pthread_setcancelstate(3)), or no
cancellation request is pending, then a call to pthread_testcancel()
has no effect.
This function does not return a value. If the calling thread is can-
celed as a consequence of a call to this function, then the function
does not return.
This function always succeeds.
