You seem to be missing the final '0' parameter, to mark the end
of the list.   You are also not providing a default value for any of
these column objects.

So you have created various rows in the table, but not set any
column values in those rows.

But there isn't any data for you to get.
None of the columns have default values, and you haven't set values
explicitly.  So no, you won't get anything from this table.


Have a look at 'agent/mibgroup/examples/data_set.c'  for one way to
populate the table.   Or else consider providing a default value instead
of the "NULL, 0"  parameters when setting up the default row.
