I know that on MacOSX / PosiX systems, there is atomic-compare-and-swap for C/C++ code via g++.

However, I don't need the compare -- I just want to atomically swap two values. Is there an atomic swap operation available? [Everythign I can find is atomic_compare_and_swap ... and I just want to do the swap, without comparing].

Thanks!
