trusty (3) pthread_testcancel.3.gz

NAME

       pthread_testcancel - request delivery of any pending cancellation request

SYNOPSIS

       #include <pthread.h>

       void pthread_testcancel(void);

       Compile and link with -pthread.

DESCRIPTION

       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.

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.

CONFORMING TO

       POSIX.1-2001.

EXAMPLE

       See pthread_cleanup_push(3).
