* This callback is not required to do anything. Generally this is useful
* for adding/reading data on demand, and the app will often put/get data as
* appropriate, but the system goes on with the data currently available
* to it if this callback does nothing.

* \param additional_amount The amount of data, in bytes, that is needed right now.
* \param total_amount The total amount of data requested, in bytes, that is requested or available.
