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_cancel() 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).
