Oh, hogwash. Of course copy-on-write is a common optimization to fork. And with vfork modifications can be visible to the other process, but the calling process is suspended until the new process exits or calls exec, so it's not useful for interprocess communication, just a side effect available very briefly. Sorry for the prior noise. -- 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.
