busGetFinish
Finishes an operation started with g_bus_get().
The returned object is a singleton, that is, shared with other callers of g_bus_get() and g_bus_get_sync() for @bus_type. In the event that you need a private message bus connection, use g_dbus_address_get_for_bus_sync() and g_dbus_connection_new_for_address() with G_DBUS_CONNECTION_FLAGS_AUTHENTICATION_CLIENT and G_DBUS_CONNECTION_FLAGS_MESSAGE_BUS_CONNECTION flags.
Note that the returned #GDBusConnection object will (usually) have the #GDBusConnection:exit-on-close property set to true.
Return
a #GDBusConnection or null if @error is set. Free with g_object_unref().

Parameters
