Determine Available Memory

Send Feedback

You can use the Windows CE GlobalMemoryStatus function to get information about the amount of available memory on the device, as shown in the following code example.

    MEMORYSTATUS   memInfo;
    TCHAR   szBuf[MAX_PATH];

    // Program memory.
    memInfo.dwLength = sizeof(memInfo);

    wsprintf(szBuf, __TEXT("Total RAM: %d bytes\n Free: %d \nUsed: %d"), 
        memInfo.dwTotalPhys, memInfo.dwAvailPhys, memInfo.dwTotalPhys — 
    MessageBox(hwnd, szBuf, __TEXT("Program Memory"), MB_OK);

    // Storage memory.
    // dwStoreSize isn't exact due to compression. 
    wsprintf(szBuf, __TEXT("Free: %d"), si.dwFreeSize);
    MessageBox(hwnd, szBuf, __TEXT("Storage Memory"), MB_OK);


Note   GetStoreInformation is deprecated. Use GetDiskFreeSpaceEx instead.
