- * bus_path_encode_unique() - encode unique object path
- * @b: bus connection or NULL
- * @prefix: object path prefix
- * @sender_id: unique-name of client, or NULL
- * @external_id: external ID to be chosen by client, or NULL
- * @ret_path: storage for encoded object path pointer
- *
- * Whenever we provide a bus API that allows clients to create and manage
- * server-side objects, we need to provide a unique name for these objects. If
- * we let the server choose the name, we suffer from a race condition: If a
- * client creates an object asynchronously, it cannot destroy that object until
- * it received the method reply. It cannot know the name of the new object,
- * thus, it cannot destroy it. Furthermore, it enforces a round-trip.
- *
- * Therefore, many APIs allow the client to choose the unique name for newly
- * created objects. There're two problems to solve, though:
- *    1) Object names are usually defined via dbus object paths, which are
- *       usually globally namespaced. Therefore, multiple clients must be able
- *       to choose unique object names without interference.
- *    2) If multiple libraries share the same bus connection, they must be
- *       able to choose unique object names without interference.
- * The first problem is solved easily by prefixing a name with the
- * unique-bus-name of a connection. The server side must enforce this and
- * reject any other name. The second problem is solved by providing unique
- * suffixes from within sd-bus.
- *
- * This helper allows clients to create unique object-paths. It uses the
- * template '/prefix/sender_id/external_id' and returns the new path in
- * @ret_path (must be freed by the caller).
- * If @sender_id is NULL, the unique-name of @b is used. If @external_id is
- * NULL, this function allocates a unique suffix via @b (by requesting a new
- * cookie). If both @sender_id and @external_id are given, @b can be passed as
- * NULL.
- *
- * Returns: 0 on success, negative error code on failure.
