Yes. The PID is what uniquely identifies a process during its lifespan. (Technically it’s possible for running code to see its PID change if the process forks, but it’s infeasible to fork anything but a bare-metal process on a Darwin-based OS, so you’ll never have to worry about that. I’m sort of afraid to mention this because it may turn into an off-topic rathole, but I’m also afraid that if I don’t mention it someone will be all “But what about forking, huh?” ;-) —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
