If you use CF or NS (or anything build on top of that) to connect, then it should "just work". If you are using raw BSD sockets, then there is no way to connect other than using CF or NS. Also Reachability isn't meant to be used to determine online vs offline. Its meant to determine if it is a good time to try to connect or not. Due to realities of networking it is entirely possible for Reachability to tell you "try to connect" and to fail completely. Basically when using Reachability, you should always use the callback to know when to retry any previously failed connections, and once you get a callback that says that connection is possible, then you should try to make the connection, while continuing plan for possible failure. -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
