Hi Graeme,

I'm very far from beeing an expert and I faced the same problems as you when I had to write some tough MT code: no clear documentation on the subject. Confused

Thank's for the link, very interresting Razz

That AtomicVar class looks like a good idea. Should the copy constructor be
AtomicVar( const AtomicVar& p) { AtomicWrite(val, AtomicRead(p.val)); }

Yes, it was what I coded at first but it didn't compile because AtomicRead() does not accept const parameter.

Anyway this sample class needs some polishing and all the classic operators should also get overloaded.
