All,
I have been digging into the agent code for socket listening and a mechanism
to request traps from outside the agent (not using agentx). I found some
public variables that FD operations touch in the receive() function.
They are
external_readfd
external_writefd
external_exceptfd
It appears that one can setup any number of sockets to be listened on within
this main loop (up to 32) by
1. creating the socket and binding it
2. call register_readfd(socket, func, NULL);
3. Implement func to do something. (like send a trap)
Now the questions
1. There are no references to register_readfd() anywhere in the code
- so is this the intended usage?
2. I assume the socket is my own, and there need not be any SNMP
PDU. I plan on sending messages into snmpd to request a trap send.
I have version 5.2.3
Any advise is appreciated,
Adam

Subject: Writing/building my trap send code
All,
I have read through the trap send related FAQs but I have a question on
programmatic trap sending.
I see that the 'trapsend' program takes command line arguments and sends a
trap. I have an Event system and I plan on sending traps from that rather
than the command line.
I used mib2c to generate the PDU build code for my traps.
The question is, am I on my own to code/compile my the generated code with
the trapssend code and compile it into my app?
I ask because the snmpd agent can take my MIB code and compile it into the
agent quite easily. I was wondering if there is something similar for
traps.
Thanks,
Adam
