The parameters here have the same meaning as for ``efl_event_callback_add()``. Note that in order to unregister the callback you have to provide **the same parameters** you used to register it. This is because you can register different callbacks to the same event or even the same callback with different *data*.
> **NOTE:**
-> Registering and unregistering callbacks is an resource-intensive process. If you perform these operations continuously on several callbacks at the same time do so in a batch as this is more efficient. You can use ``efl_even_callback_array_add()`` and ``efl_even_callback_array_del()`` to accomplish this. Remember however that you can't unregister an individual callback which has been registered in a batch. They must all be unregistered together.
