SystemStats::getMemorySizeInMegabytes


#1

On 3GB Windows 7 (32bit) i get 2gb of ram. Windows itself is reporting 3GB of RAM (Computer->Properties).
Is this ok (due to the limit of 32bit platform) or is this a bug ?

Hmm. Looks like there’s a more up-to-date function that we should be using - does this work?

int SystemStats::getMemorySizeInMegabytes() throw() { MEMORYSTATUSEX mem; GlobalMemoryStatusEx (&mem); return (int) (mem.ullTotalPhys / (1024 * 1024)) + 1; }

almost:

MEMORYSTATUSEX statex;
	statex.dwLength = sizeof (statex);
	GlobalMemoryStatusEx (&statex);

    return (int) (statex.ullTotalPhys / (1024 * 1024)) + 1; 

seems to work fine (extracted from MSDN)

Thanks!
