1. GlobalMemoryStatus( ) function is reporting Total
Physical Memory only upto 2 GB.  
With /LARGEADDRESSAWARE option will fetch upto 4GB.  But I
found this might not work, if it is used in a DLL.  Is
this information true?
2. GlobalMemoryStatusEx ( ) is not getting compiled from
VC++ 6.0 as it is not there in Winbase.h.  
It gives compilation error "error
C2065: 'GlobalMemoryStatusEx' : undeclared identifier".
But the MSDN documentation says it is Platform SDK.  When
compiling this API, do we need to install any third party
software or packages or do we need to include any lib.  
Kernel32.lib is included while compiling but still
compilation fails.
3. GlobalMemoryStatusVlm() is not in the documentation but
available in Winbase.h.  With this function, compilation
and linking goes well but while executing, it throws up
and error message saying "This function entry point is not
found in Kernel32.dll"

I tried to load this dll using LoadLibrary and
GetProcAddres() but GlobalMemoryStatusVlm() function is
not there in Kernel32.dll.  Is there any way I can use
this function?
