Before writing such statement try to write some code or look inside GTK2!!!!
Look to structure of iterator:

struct _GtkTreeIter{
   gint stamp;
   gpointer user_data;
   gpointer user_data2;
   gpointer user_data3;
};

also look to first strings of
gtk_list_store_remove (GtkListStore *list_store, GtkTreeIter  *iter){
...
   g_return_if_fail (VALID_ITER (iter, list_store));
...

there is apropriate define:
#define VALID_ITER(iter, list_store) (iter!= NULL && iter->user_data != 
NULL && list_store->stamp == iter->stamp)
....
