Not getting specific trap

I am trying to learn SNMP
This is my first snmp agent code... 
In this i am trying to generate my Trap for first system status of first row.
can any one tell me that why my agent is unable to generate the trap.
and how can i put values of ip. 

#include <net-snmp/net-snmp-config.h>
#include <net-snmp/net-snmp-includes.h>
#include <net-snmp/agent/net-snmp-agent-includes.h>
#include "telecrbt.h"
