At least, that's the way it's coded and should work. Note that _nanosleep() isn't. By design, if libc is using _nanosleep() in places, then that wouldn't cause a cancellation point. > (this would also cover usleep()) Hmm, is your real complaint that usleep() is not a cancellation point? usleep() should be a cancellation point, so you can fix it if you want (s/_nano/nano/ and remove the namespace stuff). -- DE
