pthread_testcancel - request delivery of any pending cancellation request
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 canceled as a
consequence of a call to this function, then the function does not return.
This function always succeeds.
For an explanation of the terms used in this section, see attributes(7).
