Well, I did suggest a longer development freeze, but was shot down
in flames. I'm just following the general trends :-)

Fine. I'll pick that up later.

Robert> Hmm.. that's not good. Can you send me your test MIB?
Try
mib2c -c mib2c.mfd.conf NET-SNMP-EXAMPLES-MIB::netSnmpIETFWGTable
and then look at 'netSnmpIETFGWTable_data_access.c'
Immediately following the end of the Example Code block (lines 264/5 in
my version), there's mention of 'nsIETFName' (which *is* declared in this
routine), followed by nsIETFWGChair1 (lines 298-307) and nsIETFWGChair2
(lines 326-335) which aren't.

Robert> Oh bother. I thought I had done pretty well with the comments.
Actually, the problem I'm finding is that there's almost too *much*
description (some very localised, some more general), and it's difficult
to get a clear overview. I'm sure it will all fall into place once I've
a better idea of how it all fits together, but at the moment I feel like
I'm drowning in caterpillers :-)
That's actually why I've repeatedly putting off looking at this helper.
Every time I started, I kept feeling overwhelmed!

Thanks - will do.
Minor point - that last section seems to have hardwired references to
'ipAddressIfIndex' rather than xxxColumn. It's fairly clear what you
mean, but....

OK - that would let me insert stuff within the 'myTable_container_init'
routine. Is there any way to get hold of the container at a later
stage - e.g. in the 'initialize_table_myTable' or 'init_myTable' routines
(where this has tended to be handled with the other helpers) ?
Or is that what you mean by:
Robert> 2) put a function in myTable_interface.c to return the container
