first of all, using GetHashValue as unique ID is probably not a good idea, but I guess you mean something slightly different there.

Yeah, The IDs are not "really" meant to be unique. Bad wording. They are used in cache management, and dword is sufficient in my case.

But exactly for this reason we have (for quite a long time) FoldHash function, which IMO seems ideal for you scenario. It takes hash_t and produces dword, while bringing entropy back to lowest bits

Well, I did not know that, because, you know, lack of documentation... Smile

But this is good news. I'll test with FoldHash and look into the code ASAP.

(BTW, look at implementation, I think it is one of more clever ideas from me...

You have a lot of clever ideas. The main reason why I prefer U++. Smile

Thank you!
