Thanks for reply.
I write the debug information at the beginning of the callback function,
tring to print message every time it is invoked.
In my imaginatine, this callback function is called every time when a get
request is coming. Of course, when the request is asking for the information
in the perticular table. But I can't see the information on the screen every
time.Some time it is printed, but not for sure.
I use the MIB browser to see what happens. Every time it returns a value,
which is the value set by me in the callback function. But no debug
information printed on the screen.That is why I am curious about the
operation of Net-Snmp.
I want to know whether the callback function is invoked when a request is
coming?
Thanks
