RE: Raw-table doesn't work.

Hi Dave

The handler is NOT called when a "get" request is sent (We get a "No
Such Object available on this agent at this OID" respond).
However, it is called for a getnext request.

Got any clue?
Thank you

Are you sure that the handler isn't being called at all?
Or is it simply that the agent isn't returning the expected results?

I don't see any debug or trace statements in the handler,
so it's difficult to know exactly what testing you've done.


Following a quick look at the code, I have two main comments:

  a)  I'm not sure whether you actually need the
       nsDemodEventsTable_entry structure.   You could
       probably use the ns_entry structure directly,
       and avoid having to copy data between the two.

  b)  There seems to be some confusion between logical
        and bitwise operations.

Statements such as
        tmp = *(idx->val.integer) < 32;
                  are setting a boolean value   (is the value less than
32)
rather than a left-shift  (high-order 32 bits), which I suspect is
what's intended.
And similarly for

     *(idx->val.integer) = (event->utc.tv_sec) && 0xFFFFFFFF;

which will set the index value to 1 regardless
     (anything AND true is true).
This probably ought to be using a bit-wise OR ('&')
rather than logical OR ('&&')

Both of those would explain why the agent wasn't returning the
correct results,   but not why the handler wasn't being called at all.

If that is actually what is happening, then I'm at a loss to explain
why.

Dave

PS:  Please post your queries *once*
   There's no point in sending the same request twice,
just to add a missing signature!
