You rewrite the function call so that it follows the type system of the
language. This will require bouncing the control through an intermediate
static function within aio_notify.c:

    static void *notify_func_wrapper(void *arg)
    {

You use the void * parameter of this function to pass in a pointer to the
right context information so that a call can be made to to the user's
registered notification function. The call will pass the union directly, e.g

	struct sigevent *sigev = arg;
	sigev->sigev_notify_function(sigev->sigev_value);
	return 0;
    }

The pthread_create call is then modified:

    if (pthread_create(&tid, pattr, notify_func_wrapper, sigev) < 0)
	result = -1;

Try this, see if tst-aio5.c passes.
