That sounds like a good approach, but it’s not 100% reliable. If the creating process opened the file without requesting an exclusive lock, then your open call will succeed even though the file is still open. Unfortunately you probably can’t do any better than that, since there’s no cheap way to find out if another process has the file open. —Jens_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
