Following the change to use the C domain for parsing, update all existing :cpp:func: references to :c:func:. Remove the parentheses as well, if used, because they are not needed, this is already known to be a function, and how it is displayed in the documentation later is a semantic decision done by the output builder.

Connection Management
|
|
#####################
|
|
|
|
The Zephyr Bluetooth stack uses an abstraction called :c:type:`bt_conn`
|
|
to represent connections to other devices. The internals of this struct
|
|
are not exposed to the application, but a limited amount of information
|
|
(such as the remote address) can be acquired using the
|
|
:c:func:`bt_conn_get_info` API. Connection objects are reference
|
|
counted, and the application is expected to use the
|
|
:c:func:`bt_conn_ref` API whenever storing a connection pointer for a
|
|
longer period of time, since this ensures that the object remains valid
|
|
(even if the connection would get disconnected). Similarly the
|
|
:c:func:`bt_conn_unref` API is to be used when releasing a reference
|
|
to a connection.
|
|
|
|
An application may track connections by registering a
|
|
:c:type:`bt_conn_cb` struct using the :c:func:`bt_conn_cb_register`
|
|
API. This struct lets the application define callbacks for connection &
|
|
disconnection events, as well as other events related to a connection
|
|
such as a change in the security level or the connection parameters.
|
|
When acting as a central the application will also get hold of the
|
|
connection object through the return value of the
|
|
:c:func:`bt_conn_create_le` API.
