    NAME:       DllMain

    SYNOPSIS:   Win32 DLL Entry point.  This function gets called when
                a process or thread attaches/detaches itself to this DLL.
                We simply call the Win3 appropriate DLL function.

    ENTRY:      hDll - DLL Module handle
                dwReason - Indicates attach/detach
                lpvReserved - Not used

    EXIT:

    RETURNS:    TRUE if successful, FALSE otherwise

    NOTES:      This is the typical Win32 DLL entry style.

                This is Win32 only.
