(Of course, that assumes NULL is 0, but I don't
think I've run into any
architecture so braindead as to not have NULL=0.)
It has nothing to do with machine architecture. The C standard
says 0 coerces to the null pointer. NULL, defined in <stddef.h>,
is part of the library, not the language. I always use 0,
because NULL is a frill.
