I'm wondering about a routine that gets called when the IOC is
exiting - when the record is destroyed.

Ah, now I see - you're probably talking about a soft IOC running on
Windows, Linux or Solaris (on vxWorks your question doesn't make much
sense, which is why Noboru and I were confused to begin with). The IOC
code wasn't really written with closedown in mind because it was
originally aimed at long-running vxWorks systems, so there's nothing quite
like what you're after built into it.
However, there's no reason why code intended for host-based IOCs can't
register its own exit handler using the standard OS atexit() method,
although you can't rely on the order in which this is run related to tasks
being closed down etc.
