simple tables and dataset

[mo...@frakir.org]

I'm trying to implement an agent for some tables. Said tables are RAM
resident, but I do need a hook to make system changes when table
columns are changed, and to return an error if a system change fails.

This seemed like a problem for the dataset style with a table_handler.
I've got snmpsets and gets/walks working at a basic level. Problem:
nothing that I do in the table_handler function seems to let me return
an error. I tried making the whole function be just "fprintf(stderr,
"here\n"); return SNMP_ERR_GENERR;", and while I get "here" printed
out, snmpsets are still successful. The example disman code just has
stub handlers. Is there something I'm missing, or do I need to use a
different mib2c template (ie. iterate)?

Platform: netsnmp 5.1 compiled from source under linux.

Thanks!

Use
netsnmp_set_request_error(reqinfo, request,
SNMP_ERR_GENERR);

to set an error for a given varbind.
