That's part of the standard process of processing an incoming PDU. It's not really part of the public API. It's certainly not relevant to your main requirement. > However, I don't realize how to apply callback to implement trap that can > make it receive some system call.

Either use the "signal" mechanism (if your system call would trigger on this), or have a look at "snmp_alarm(3)" - that's the standard way of regularly checking for significant things happening. In general, you're better off browsing through the man pages, and getting a feel for what various API calls are meant to do, rather than reading the raw code and trying to guess how things might work.
