[PATCH BlueZ 3/8] gap: Make use of service user_data to store service context

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>

Instead of storing service context data in a list this make use of
btd_service_set_user_data to store the context data which later can be
retrieved with btd_service_get_user_data.
