gtk_tree_model_get_iter_first

[Neil Zanella <nzanella gmail com>]

Hello,

I would like to know how come gtk_tree_model_get_iter_first doesn't
just return a
GtkTreeIter and set it to NULL when the end of the iteration is
reached rather than
returning a boolean? Why is the design of the API such that it returns a boolean
instead? Wouldn't the approach I describe simplify the API?

Thanks,

Neil
