Thanks Dave! I've got it working now.
And you've given me a lot of food for though with the earlier explanations
as well. It's got me thinking - what are varbind structures? From what I
gather, they seem to be the primary structure by which net-snmp passes data
around - at least as the interaction point with external sources.
I've seen the structure definition, and it contains a lot - OID values, data
information ... etc. I'm guessing that this was introduced during the
net-snmp 5.x upgrade ?
Puzzling over the rest of the code,
