Have you read the Threading Programming Guide? I'm not a Windows developer, so I had to look up the MSDN docs, and based on those it seems like you want the OSAtomicIncrementxxx (and matching OSAtomicDecrementxxx) as direct analogues. However, since it sounds like you are trying to use these functions to implement locking in a multithreaded application, perhaps you should also examine whether higher level constructs would prove sufficient. A couple such mechanisms you can read about are NSLock and the @synchronized directive. GCD has some features (dispatch semaphores and barrier blocks come to mind) that may also be helpful in certain circumstances. -- Conrad Shultz Synthetiq Solutions www.synthetiqsolutions.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
