Hey,
=20
I'd like a simple C++ API for implementing MIBs.
Basically I'd like the new API to allow an object to implement a leaf,=20
meaning that the object should register for handling a certain leaf, and
it would have some predefined handle() method which will be called when
leaf processing is needed.
This would require some sort of special registration.
=20
Possibilities I thought of:
1) find out if there is already a C++ API?
=20
2) Use the OLD-API, and register a variableN array in which the
FindVarMethod would
use the oid as a key to lookup an handler_object in a global
data-structure,=20
and invokes a "handle" method of the handle_object.

3) Use the new Net-SNMP handler mechanism to register a handler with
some cookie which will contain the object (this) pointer.

Questions:
---------------
=20
A) Is there a C++ API for this? ( I guess not...not yet)
=20
B) since possibility number 1 is a bit awkward, I'll refer to the 2nd
possibility:
1) How do I register a handler with a cookie?
=20
C) Any better Ideas?
=20
thanks,
Erez.
