(b) Is id number N used or not? If I interpret things correctly, in case (b) if N is larger than the the highest id number currently stored it might still return non-NULL (if lower order bits match lower order bits of a different stored id). [Would it be sufficient for the caller to keep track of the highest allocated ID and check before calling, or is the masking sometimes stronger than that?] Alasdair -- agk@xxxxxxxxxx
