void gsk_dbi_synchronized_object_add_sync_notify (GskDbiSynchronizedObject * object, GskDbiSynchronizedObjectCallback sync_notify, gpointer sync_notify_data, GDestroyNotify sync_notify_data_destroy)
The object to which to add a synchronization notify callback.
The synchronized object notify callback to register. Note that this function is not necessarily, e.g., if synchronization is not performed because the object has not changed, or if synchronization was prevented via gsk_dbi_synchronized_object_dont_sync ().
Data passed through unmodified to callback.
This is called when the sync_notify_data is no longer in use. This is guaranteed to be called exactly once.
