Yes, but a 0 pointer value has not the meaning of an int value 0.

(Probably badly worded.)

I meant; the internal binary representation of a 0 pointer value
has not necessarily the internal binary representation of an int
value 0. (So you could use it also in architectures like the one
you mention.)

use the NULL macro in both C and C++ code.
