GtkAccessibleupdate_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 GtkAccessibleRelation requires a list of references, you should pass each reference individually, followed by NULL, e.g.

gtk_accessible_update_relation (accessible,
                                GTK_ACCESSIBLE_RELATION_CONTROLS,
                                  ref1, NULL,
                                GTK_ACCESSIBLE_RELATION_LABELLED_BY,
                                  ref1, ref2, ref3, NULL,
                                -1);

This method is not directly available to language bindings.

The implementation of this method is provided by gtk_accessible_update_relation_value() in language bindings
