Ok, just checking. On Sat, 28 Aug 2004 14:04:55 +0530 Virender wrote: VSC> I am implementing a sub-agent for which the requirement is somewhat VSC> unusual. It isn't actually all that unusual.

The problem is that the helper handlers above the generated code are not designed to pass requests for unknown OIDs down to the lower handlers. If you know all your indexes in advance, I think array-user would be the way to go. If your indexes change dynamically, then you will have to register a basic handler, and duplicate some of the work the other helpers were doing for you. Unfortunately, there aren't any examples that I can think of off the top of my head. The closest would be agent/mibgroup/examples/delayed_instance.c, which doesn't user any helpers, but is just for a single instance. But it should give you the basic idea: register for your top level oid, and then delegate the request while you query your NE. You'll have to deal with GEXTNEXT processing yourself, by examining the OIDs in the incoming requests. -- Robert Story; NET-SNMP Junkie <http://www.net-snmp.org/> <irc://irc.freenode.net/#net-snmp> Archive: <http://sourceforge.net/mailarchive/forum.php?forum=net-snmp-users> You are lost in a twisty maze of little standards, all different. ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
