◆ spa_dbus_connection_get

#define spa_dbus_connection_get (   c)    spa_dbus_connection_call_vp(c,get,0)

Get the DBusConnection from a wrapper.

Note that the returned handle is closed and unref'd by spa_dbus immediately before emitting the asynchronous "disconnected" event. The caller must either deal with the invalidation, or keep an extra ref on the handle returned.

Parameters
connthe spa_dbus_connection wrapper
Returns
a pointer of type DBusConnection

spa_dbus_connection.get

◆ spa_dbus_connection_destroy

#define spa_dbus_connection_destroy (   c)    spa_dbus_connection_call(c,destroy,0)

Destroy a dbus connection wrapper.

Parameters
connthe wrapper to destroy

◆ spa_dbus_connection_add_listener

#define spa_dbus_connection_add_listener (   c,
  ... 
)    spa_dbus_connection_call(c,add_listener,1,__VA_ARGS__)

Add a listener for events.

Function Documentation

◆ spa_dbus_get_connection()

static struct spa_dbus_connection * spa_dbus_get_connection ( struct spa_dbus dbus,
enum spa_dbus_type  type 
)
inlinestatic

Get a new connection wrapper for the given bus type.

The connection wrapper is completely configured to operate in the main context of the handle that manages the spa_dbus interface.

Parameters
dbusthe dbus manager
typethe bus type to wrap
errorlocation for the DBusError
Returns
a new dbus connection wrapper or NULL on error
