DefWindowProc

[GreenDay2001]

here's a piece of window procedure. What does DefWindowProc do in this program.

LRESULT CALLBACK WndProcedure(HWND hWnd, UINT Msg,
               WPARAM wParam, LPARAM lParam)
{
    switch(Msg)
    {
    case WM_DESTROY:
        // user wants to exit
        PostQuitMessage(WM_QUIT);
        break;
    default:
        // Hand off unprocessed messages to DefWindowProc
        return [B]DefWindowProc(hWnd, Msg, wParam, lParam)[/B];
    }
    
    return 0;
}
