Watch Virtual / Physical Memory Usage

With previous article http://twnin.blogspot.com/2012/05/watch-process-memory-usage.html
There is another way to watch memory usage in program with win32 api.

    MEMORYSTATUS ms;
    ms.dwLength = sizeof(ms);
    GlobalMemoryStatus(&ms);

    const int nBufSize = 512;
    TCHAR chBuf[nBufSize];
    ::ZeroMemory(chBuf,nBufSize);

    // Process-specific info (for calling process)
    wsprintf(chBuf,_T("TotalVirtual: %ld\n"), ms.dwTotalVirtual);
    OutputDebugString(chBuf);
    wsprintf(chBuf,_T("AvailVirtual: %ld\n"), ms.dwAvailVirtual);
    OutputDebugString(chBuf);

    // Process virtual memory usage (reserved + commit)
    wsprintf(chBuf,_T("UsageVirtual: %ld\n"), ms.dwTotalVirtual - ms.dwAvailVirtual);
    OutputDebugString(chBuf);

    // System info
    wsprintf(chBuf,_T("MemoryLoad: %ld\n"), ms.dwMemoryLoad);
    OutputDebugString(chBuf);
    wsprintf(chBuf,_T("TotalPhys: %ld\n"), ms.dwTotalPhys);
    OutputDebugString(chBuf);
    wsprintf(chBuf,_T("AvailPhys: %ld\n"), ms.dwAvailPhys);
    OutputDebugString(chBuf);

    // System usage
    wsprintf(chBuf,_T("UsagePhys: %ld\n"), ms.dwTotalPhys - ms.dwAvailPhys);
    OutputDebugString(chBuf);

    // Unused/unsupported
    wsprintf(chBuf,_T("TotalPageFile: %lu\n"), ms.dwTotalPageFile);
    OutputDebugString(chBuf);
    wsprintf(chBuf,_T("AvailPageFile: %lu\n"), ms.dwAvailPageFile);
    OutputDebugString(chBuf);
