Rather than do that, create another, custom CFRunLoopSource that can be used to wake up the run loop (via CFRunLoopSourceSignal) when the condition changes. Then instead of just condition = NO; use condition = NO; CFRunLoopSourceSignal(mySource); to wake the run loop immediately. That'll let you set a nice high timeout rather than something low like 0.5 or 1, and prevent you from wasting CPU. -- Chris _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
