const (

	pluginName    = "testplugin"

	pluginVersion = 0x00010000

)

func Load(register func(name string, version uint64) error) error {

	err := register(pluginName, pluginVersion)

	if err != nil {

		log.Println(err.Error())

		return err

	}

	log.Println("loading test plugin")

	result := hotplugin.Call("testplugin", "Test", "my world")
