U grill me with all those questions :)

No, we cannot use VirtualAlloc function directly.

Since you're only interested in allocating memory in page sizes

For convienience I provide you with a link to Interix migration/porting

Look in chapter 9, although it is very thin on the subject of memory mapped 
files.

It's getting late for me. I'll try to look on the subject in the weekend...
