I think that would complicate the logic too much, moreover, I do not see the advantage in doing this? >>2) (For the Microsoft/Windows buffs) Is it possible to allocate more than 256M >>in a contiguous chunck under older Windows versions? > >Under Win2000 with 1 GB RAM, I was able to allocate (malloc) around 900 MB, I >wasn't able to allocate significantly more on a system with 2 GB.
