* GtkTreeIterCompareFunc:

* @a: A #GtkTreeIter in @model
* @b: Another #GtkTreeIter in @model
* @user_data: Data passed when the compare func is assigned e.g. by
* gtk_tree_sortable_set_sort_func()
*
* A GtkTreeIterCompareFunc should return a negative integer, zero, or a positive
* integer if @a sorts before @b, @a sorts with @b, or @a sorts after @b
* respectively. If two iters compare as equal, their order in the sorted model
* is undefined. In order to ensure that the #GtkTreeSortable behaves as
* expected, the GtkTreeIterCompareFunc must define a partial order on
* the model, i.e. it must be reflexive, antisymmetric and transitive.
*
* For example, if @model is a product catalogue, then a compare function
* for the "price" column could be one which returns
* <literal>price_of(@a) - price_of(@b)</literal>.
*
* Returns: a negative integer, zero or a positive integer depending on whether
* @a sorts before, with or after @b
