atomic-swap

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!

I want to verify that my understanding is correct. This kind of thing is tricky so I'm almost sure I am missing something. I have a program consisting of a real-time thread and a non-real-time thread. I want the non-RT thread to be able to swap a pointer to memory that is used by the RT thread… >>> More
