GtkTreeIter assignment

[Vlasov Vitaly <vnigtha gmail com>]

Hello list.

Is that normal, to assign one GtkTreeIter to another?

For example:
void add_new( ... , GtkTreeIter *iter)
{
    GtkTreeIter *default_iter;

    if(iter != NULL)
    {
       default_iter = iter; <-- is that noraml??
    }
    gtk_tree_store_append(&default_iter);
}
