I trust you're actually checking the return value of this
routine, to tell whether to continue processing or not?

How is 'p' being initialised?
I'd expect you to extract the index from the OID returned
by 'header_simple_table', and use this to select the
appropriate row of the table.

But you don't show any of this code.

See above.
How is 'p' set?

Then I'm not quite sure why you are using this particular test?

The 'var_fnc' routine will be called *once* to process *one*
varbind. The utility routine 'header_simple_table' will validate
the request (and update the OID for a GETNEXT request).

Then it's up to you to locate the row that's being asked for,
and return the appropriate column value. If you're asked
for a value from the first row, that's what you should return.
If you're asked for a value from the third row, then that's
what you should return. If you're asked for a value from the
fourth row, then you should return NULL.


With the limited code that you've shown us, it's impossible to
provide any more detailed advice.
