Hi,

I was looking for some kind of atomic counter which is able to deal with 64 bit values on 32/64 bit machines.

I was just wondering if this could be done with this library on Windows (yes, I know). As far as I can see it uses the InterlockedIncrement() API methods internally. But for 64 bit values you have to use InterlockedIncrement64().

Has anyone of you tried this?

FWIW, you can do a loop-free 63-bit counter on a 32-bit machine by using the following clever algorithm from Joe Seigh: http://groups.google.com/group/comp.lang.asm.x86/browse_frm/thread/15271b4da...
