Re: multiple Sub-agents managing the same table

Tell me if I'm wrong, but for me, nothing exists in the library net-snmp to 
manage get/get_next requests for tables registered with range_subid and 
range_ubound => by the way, this is a bug, no?

the API netsnmp_create_handler_registration is an API able:
- to register a whole table
- to register only columns of a table for a specified index

To my point of view, the helper functions must be able to manage these two 
possibilities , and this is not the case.

Indeed, when registering columns of a table, the rootoid_len should be set 
(at the end of the process) to the length of the Oid - 3 (the finl 
rootOidLen must point to the Table Oid, and not the index!). I think I will 
solve it this way.

Of course, my hack is an uggly hack!!! But the solution exposed previously 
(set correctly the rootoid_len) is for me a clean and safe one.

But perharps, I'm wrong. I'm not as experienced as you on net-snmp.
