PTHREAD_TESTCANCEL(3)					     Linux Programmer's Manual					     PTHREAD_TESTCANCEL(3)

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(3)
       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).
