The documentation Robert quoted seems to imply that multitasking doesn't result in your sockets behaving any differently than they might under other normal circumstances. Which means that you should be perfectly okay with using BSD sockets. The documentation you've quoted seems to me to simply state that the higher-level networking constructs properly handle socket errors, which means they correctly deal with app backgrounding. Have you tried using BSD sockets and gotten any bad results? There's no point going around and around in circles without actually trying the code. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
