It's required because the arguments are simply passed on the stack one after the other. Their size is known from the type, but not their number. The nil is a sentinel so the code doesn't simply fall off the end of the stack and into garbage memory looking for parameters. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
