Getting listening port number while processing request

Hello,

I've been digging around in the library for a while to check out
whether the port number that the agent listens on, if it listens on
multiple ports, can be retrieved via the API, while the snmpd
processes a request via snmpget or snmpset.

I could not find a way to display the port number, also not using the
various debug tokens.

Question: Is there a way to retrieve the port number that a request
was received on, or do I need to hack the net-snmp library itself, or
is that never possible?

With kind regards,

Teus Benschop
