handler problem (where to get table index)

Hi:

I'm brand new to SNMP (thought I'd start with that).

I'm trying to write a table handler. I used mib2c to generate the
source code. Everything is going well...except in the handler I cannot
find the value of the table index during a set operation. I can find
the type of the data using requests->requestvb->type.
Based on the type, then I can find the value of the data using requests->requestvb->val.integer
(if it was integer data). However, I can't find the index,
element, or whatever its called. I tried using both requests->index
and requests->requestvb->index
but both are are set to 1. The
handler must be automatically called from the master agent.

I check if reqinfo->mode == COMMIT. When this is true, I need to
pass the type, value, and index to my own routine. The handler's
definition (generated by mib2c is:

/** handles requests for the
phaseTable table, if anything else needs to be done */

int

phaseTable_handler(netsnmp_mib_handler
*handler,

netsnmp_handler_registration *reginfo,

netsnmp_agent_request_info *reqinfo,

netsnmp_request_info *requests)

As an example, if I type the following:

snmpset -v 2c -c private localhost NTCIP1202-2004::phaseWalk.4 i 20

NTCIP1202-2004::phaseWalk.4 = INTEGER: 20

My agent handler (PhaseTable_handler) debug will dump out:

type 2 -- Object
type is integer from requests->requestvb->type

value
length 4 -- length is 4 bytes from requests->requestvb->val_length

name
44137224 -- OID is some large number requests->requestvb->name

data
20 -- data is 20 requests->requestvb->val.integer

index
1 -- index is wrong. requests->index or
request->requestvb->index

The index should be 4. But, it never is. My question is how do I get
the index from the reqinfo or requests handler data?

Thanks for any replies.

Mark
