GetSystemMemoryDivision

al12559 · Jun 11th 2013

Hello,

when I use memcfg.exe, the ratio of storage memory to program memory is being adjusted as desired.
I wanted to include GetSystemMemoryDivision()/SetSystemMemoryDivision() in my application, but these functions are unknown (Visual Studio 2008). Coredll.lib is included in my project settings.
Do you have any solution?

Thank you in advance

Hello,

Code

extern "C" DWORD SetSystemMemoryDivision ( DWORD );
extern "C" BOOL GetSystemMemoryDivision (
LPDWORD lpdwStorePages,
LPDWORD lpdwRamPages,
LPDWORD lpdwPageSize );
bool MySetMemDivision( void )
{
CRegKey cRegKey;
DWORD StorePages, RamPages, PageSize, TotPages;
DWORD dwMemDivision = 70;
if( !GetSystemMemoryDivision(&StorePages, &RamPages, &PageSize) )
{
return false;
}
TotPages = StorePages+RamPages;
StorePages = TotPages * (100 - dwMemDivision) / 100;
DWORD dwRet = SetSystemMemoryDivision ( StorePages );
if( /*SYSMEM_FAILED*/3 == dwRet )
{
return false;
}
return true;
}
