How do the iterator 'get_{first,next}' hook routines
obtain the list of entries to work with?
Do you have an internal list, or something similar?
How is this generated?

Then the iterator hook routines need to omit that
entry from the list that they return.

RowStatus is the standard mechanism for having a management
client application instruct the agent to delete a row
from the table (together with removing whatever that
row refers to). In this case, that would probably
correspond to shutting down the corresponding process.
If you're just trying to monitor the existing state
of the system, then RowStatus control is not relevant.
Concentrate on the iterate hook list.
