Routine Description:

    This function is DLL main entry point, at here we will save the module
    handle, in the future we will need to do other initialization stuff.

Arguments:

    hModule     - Handle to this moudle when get loaded.

    Reason      - may be DLL_PROCESS_ATTACH

    Reserved    - reserved

Return Value:

    Always return 1L
