public void update_relation (...)
Updates a list of accessible relations.
This function should be called by `GtkWidget` types whenever an accessible relation change must be communicated to assistive technologies.
If the [[email protected]] requires a list of references, you should pass each reference individually, followed by null, e.g.
```c gtk_accessible_update_relation (accessible, GTK_ACCESSIBLE_RELATION_CONTROLS, ref1, NULL, GTK_ACCESSIBLE_RELATION_LABELLED_BY, ref1, ref2, ref3, NULL, -1); ```
| this |
a `GtkAccessible` |
| ... |
a list of relation and value pairs, terminated by -1 |
| first_relation |
the first `GtkAccessibleRelation` |
