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() 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).
