RE: Table GetNext for next column

Dave,
	Thanks for the response.

1. I am following iterator approach by implementing
Get_first_data_point, Get_next_data_point and Table_handler functions
for each table. At initialization I am registering all above
corresponding functions with table_iterator Using
netsnmp_register_table_iterator API.

My Get_first_data_point will fectch the first index from the application
code which will supply values for SNMP.

My Get_nextdata_point will fetch the next index from the application
code by taking the index we supplied in Get_first_data_point.

My handler function will take the indexes from the request and retrieve
the value corresponding to this instance from application.

2. What is the simplest way of sending back the agent that no more
instances of this object exists? I am doing it by setting the type of
varbind in request to (request->requestvb->type) SNMP_NOSUCHOBJECT. Is
it correct way? Please correct it if it is not.

3. Please let me know if you need more details.

PS: Sorry! The bounce mail was in some other folder of my mail-box.
Could not recognize that. Sorry for flooding the same message again.


Thanks,
Madan

What do you mean by the "NETSNMP way"?
There are at least four or five different approaches used in the
Net-SNMP
agent.   Which one(s) are you using?

Normally, you'd simply indicate that there are no more instances of this
particular MIB object.   The agent framework would then automatically
move on to the next column.

Given the lack of information about exactly what you're currently doing,
then not really!

A few more details would be helpful - such as which helper you're using,
and how you are currently reporting the end of the column.
