<?><?><?>
       pthread_testcancel - request delivery of any pending cancelation
       request

LIBRARY
       POSIX threads library (libpthread, -lpthread)

<?><?><?><?><?><?><?><?><?>
       #include <pthread.h>

       void pthread_testcancel(void);

<?><?><?><?><?><?><?><?>
       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.
