NAME

       pthread_testcancel - request delivery of any pending cancelation request

LIBRARY

       POSIX threads library (libpthread, -lpthread)

SYNOPSIS

       #include <pthread.h>

       void pthread_testcancel(void);

DESCRIPTION

       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.

RETURN VALUE

       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.

ERRORS

       This function always succeeds.
