void        g_hash_table_foreach        (GHashTable     *hash_table,
                                         GHFunc          func,
					 gpointer        user_data);

typedef void            (*GHFunc)               (gpointer       key,
                                                 gpointer       value,
                                                 gpointer       user_data);


Thesa are the prototypes. The pointer user_data that you gave to foreach is
blindly passed to func. This enables tyo to use one same function with
various options.
