Because you are assigning a value to the (sole) instance of the
scalar object SNMPv2-MIB::snmpTrapOID.
All scalar instances have the instance subidentifier '0'
> 2. What is a role of snmp_add() and snmp_add_var() functions?
"snmp_add" creates an SNMP session to the specified destination.
It would probably more typically use "snmp_open" or "snmp_sess_open"
"snmp_add_var" takes a PDU structure, and adds the specified varbind
to the payload. This is used for building up the SNMP request, before
sending it to the destination.
