How to trigger the sending of a v2 trap

Dear:

I have a problem about how to trigger the sending of a V2 trap

In the program,Iuse:

$snmpset -v2c -c private localhost snmptrap.0 i 1

Then,it can send a trap to the destination ip.

Or I test like this, In the var_snmp:

case OLTFIRMWAREVER:
*var_len = sizeof(oltfirmwareVer);
write_exampletrap2(COMMIT,NULL,0,0,NULL,NULL,0); //test sending trap
return (u_char *) oltfirmwareVer;
case CHIPNEWERFIRMWAREVER:
*var_len = sizeof(g_olt_dev.chipNewerFirmwareVer_tmp);
return (u_char *) g_olt_dev.chipNewerFirmwareVer_tmp;

When I use the snmpget commond :snmpget -v2c -c private localhost oltfirmwareVer.0

It can also send a v2 trap.

But all these are not what I need.I want to send a trap when the trapflag=1.

I use this in my main funcation :

if(trapflag==1)

{

write_exampletrap2(COMMIT,NULL,0,0,NULL,NULL,0);

}

There are some errors. It returns:

$ No log handling enabled - turning on stderr logging

send_trap: no v2 trapOID varbind provided

What can I do to solve the problem?

Looking forward for your help!Thanks!
