Re: Windows array allocation problem

If that's true, then it's the answer to my question and the solution to my problem. If I know for sure how much will be unavailable, I can set the maximum allocation accordingly.

Note that the address space of a process can be further fragmented by
DSOs/DLLs - which can be dynamically loaded at various addresses at
run-time. Thus 'available memory' and 'available CONTIGUOUS memory'
can be two very different things...

Bottom line is that once your problem sizes start approaching 2 gbytes,
you need to start considering a change to a system supporting a 64-bit
memory model.
