netsnmp_transport_open_server  and snmp_add (or snmp_open) yes.
Those are the basic calls for setting up the listening ports.
(snmptrapd_add_session is just a wrapper round snmp_add)

    transport = netsnmp_transport_open_server("snmptrap", "udp:162");
    ss = snmptrapd_add_session(transport);


This will then call the routine "snmp_input" whenever a request is received.
