Yeah that has never correct. It used to take a single pointer argument,
no varargs (presumably because varargs was even weirder in K&R C and
awkward for syscalls), and that was still the case in 4.2BSD when
TIOCFLUSH started accepting a non-NULL argument for flags. Only NULL
and a pointer to an int have ever been valid.
