What in particular?
It's much easier to offer advice or assistance when you've
got a specific query. Something general like "flow of the code"
is very difficult to respond to. You don't even say whether
you mean the client tools or the agents.
Assuming you mean the agent, then the overall flow is
something like:
receive() loop (snmpd.c)
snmp_read()
[library parses the packet and calls]
handle_snmp_packet (snmp_agent.c)
netsnmp_handle_request
handle_pdu
handle_var_requests
netsnmp_call_handlers
which takes you into the relevant handler chain for a given
MIB object - see 'agent_handler.c', 'helpers/*' and 'mibgroup/*/*'
That should be enough to get you started.
