On VirtualAlloc's preferred addresses

[MarcelPiNacy]

Hi!

I'm developing a low-level memory manager library for C++ and I would like to know how the VirtualAlloc* functions choose the addresses that they return.

In particular I'd like to know the following:

• Does VirtualAlloc* return the lowest available address?
• Is there a chance that a future call to VirtualAlloc* might return a lower address than the one returned by the first call to it in the entire program?
• Does MEM_LARGE_PAGES alter the strategy by which addresses get chosen? Aside from the increase of the allocation granularity?

Any answers are greatly appreciated
