Re: How to use examples/notification.c (3)

Hello,

What I am trying to do is to send out SNMP trap from an embedded linux 
target for alarming purpose in case HW failure. So I see the notification.c 
is the best candidate.

I also wish to have the target respond to SNMP query.

Therefore, I'm thinking there're 2 ways
1) a) Run snmptrapd for query
    b) Compile notification.c as a stand-alone app and run it to send SNMP 
trap
    So, I'm really appreciated to your help of how to do b)
2) The notification.c is "embed" into snmptrapd so I run only 1 task for 
both

Job 1.b) could be simpler in creating a Makefile ? but 2) is simnpler in 
operation as 1 task does both jobs (sending out and responding to query)

I really appreciate to your time and help

Duy

Also note that this is an example of sending notifications from a subagent. 
Sending notifications from a separate application is a little different.
