Hence we can use this code:: - bn = BATnew(TYPE_void, TYPE_str, BATcount(b)); + bn = BATnew(TYPE_void, TYPE_str, BATcount(b), TRANSIENT); The arguments of ``BATnew`` are the types of the *head* and *tail* -columns, and the initial size of the to-be-allocated BAT. ``BATnew`` +columns, the initial size of the to-be-allocated BAT, and +``TRANSIENT`` to indicate that this BAT is temporary. ``BATnew`` guarantees that there is space for at least the specified number of elements, or it returns ``NULL``.
