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(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).
