Actually it is--in fact there can even be multiple representations that are null, but again the language is specified to take care of making NULL pointers equivalent to 0 for comparing pointers to 0 and assigning constant 0 to pointers. It's not something most of us need to worry about: obscure embedded stuff, ancient segmented architectures, different size pointers to different data types, and other such madness. -- Scott Ribe scott_r...@elevated-dev.com http://www.elevated-dev.com/ (303) 722-0567 voice _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
