- Thread-topic: MPProcessing in Lion
This past weekend I tried compiling my Snow Leopard Cocoa app in Lion (Xcode 4.3) just to make sure all was OK. I got two warnings stating that MPProcessorsScheduled and MPCreateCriticalRegion were deprecated in Lion but the relevant Lion docs did not say what they should to be replaced with.
I use MPProcessorsScheduled to create an equal number of parallel threads (for a long computation) and MPCreateCriticalRegion to serialize the core of a pseudo-random-number generator.
Two questions:
1. What should I replace these with?
2. Will that replacement also work in Snow Leopard and, if not, what if-criterion should I use to make the code work in both places?
Thanks very much for any help.
