Extra '0' for 'snmpTrapOID' in generated code ?

[Sridhar S]

Hi,

I am using Net-SNMP version 5.0.9. I need a clarification on code
generated for 'snmpTrapOID' object. 

Following the part of the code generated for the coldStart trap. I have
attached full code with the mail (coldStart.c).

static oid snmptrap_oid[] = {1, 3, 6, 1, 6, 3, 1, 1, 4, 1, 0};

According to SNMPv2-MIB, snmpTrapOID is snmpTrap.1, in that case I think
an extra '0' getting appended at the end. 

Please clarify.

Thanks
Sridhar
