(Actually, the ANSI C standard doesn't mandate that a null pointer  
have all its bits zero, so there's no guarantee that, for example,  
memset(xxx, 0, yyy) will set pointers to null.

However, null pointers are implemented, on all platforms on which we  
run, as pointers with all their bits zero, so, in practice, memset 
(xxx, 0, yyy) *will* set pointers to null on all those platforms.)
