Of course - I hadn't spotted that you'd got two registration calls
for the same registration structure.

Wrong call.
Your handler routines are written to use the 'instance' helper
(which is part of the 'scalar' handler chain).   So you *do*
want to use netsnmp_register_scalar.

The netsnmp_register_handler() call is only used when you want
control over the *whole* of an OID subtree, and will be doing all
of the OID checking yourself.  That's not true here.


Try something like:

   reg = netsnmp_create_handler_registration(....);
   reg->contextName = strdup("MyContext");
   netsnmp_register_scalar(reg);
