Will it be possible to add/implement an MIB table inside an existing daemon
using the agentx apiś ? Idea is to avoid running another sub-agent process and
avoiding IPC between the demon and agentx. The demon is multi-threaded app.
Ideal to run the agentx sub agent in a new thread.

Hi,
Is it possible to develop the sub-agent code using C++(CC) compiler? mib2c
generated code is a .c extention. I like to rename it to cpp and likes to build
using cpp compiler.
I need to do that as there are many files which are alredy in CPP and will be
the part of sub-agent code.

SNMP doesn't have a concept of "parent tables" and "child tables".

That's true. I like the cache concept. My data is outside the agent. So I have
to pull the data from different processes. I read in some net-smp page (did not
