[AGENT++] Walking table row by row using SNMP++

yes, this is the way to do it.

Yes, if the pdu size limit is not reached, you will get n rows

As the the "get bulk processing engine" does not know anything about the
table structure, after the last row, you will get the first row from
column 2 and the first object after the table.

Yes.

I just wrote, what I would expect...
