Abstraction is good.
I don't see how the NSData write allows me to append to an open file. > > Finally, you don't have to guess that it works. It's a line of code I've used > many times.

But the entire email thread could've been avoided if there were methods with obvious names (like createFileURL: or whatever). Or if NSFileHandle write... would have created the file, like NSData's write... does. Those are the inconsistencies I refer to. -- Rick _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
