int APIENTRY _tWinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPTSTR    lpCmdLine,
                     int       nCmdShow)

UNREFERENCED_PARAMETER(hPrevInstance);
UNREFERENCED_PARAMETER(lpCmdLine);

what’s the purpose of UNREFERENCED_PARAMETER here?

    It just suppresses a compiler warning about two parameters being unused in the function.

    The macro itself is probably just defined as 

    #define UNREFERENCED_PARAMETER(x) (x)

    so it references its argument but does nothing with it.
