See ~agent/mibgroup/examples/{notification.c, example.c} for examples of 
using the send_v2trap() API.  I did not see any examples using the 
send_trap_pdu() (sorry about that!).

The only time the agent needs to know the SnmpEngineID of the manager is 
at configuration time and only if the agent is configured to send 
Informs using SNMPv3 to that manager rather than Traps for 
notifications.  A manager configuring NetSNMP to receive Informs will 
know its own SnmpEngineID and will set this value in the appropriate 
SNMPv3 MIB tables.

Your application using the send_v2trap() API does not have to know the 
SnmpEngineID, SnmpEngineBoots or SnmpEngineTime values of the manager 
since the NetSNMP agent takes care of this for you.

Try the examples in notification.c and example.c using the send_v2trap() 
API and see if this code provides the remaining answers for you!
