It seems that you could have that case. You could try to walk the
virtual
address space and see what's going on. Check out VirtualQueryEx().

DWORD VirtualQuery(
LPCVOID lpAddress, // address of region
PMEMORY_BASIC_INFORMATION lpBuffer, // information buffer
SIZE_T dwLength // size of buffer
);

Two questions:
1.
How to set lpAddress initially?

You can start it at 0 and then increment it based on the info returned in
lpBuffer (i.e. look up MEMORY_BASIC_INFORMATION).

2.
I will collect sets of memory regions with different attributes. However,
I
do not know how to interpret these sets.
Furthermore, I guess I will end up with the same amount of memory, which
"Process viewer" is presenting.

Yes, but this will give you more info than a simple sum. To understand what
you're being given again see MEMORY_BASIC_INFORMATION.

BTW, what failture code to you get from the allocation functions that you
call?

HTH,
