Nowhere does the documentation say this. You can't call -[NSLock lock] multiple times, because you'll block on a lock you already have (that's why we have recursive locks). Otherwise -[NSLock tryLock] would be quite useless, wouldn't it? >From the questions you're asking, it sounds like you're going to implement a spinlock on top of NSLock. Don't do this. Just use @synchronized. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
