Re: sysctl(3) interface

I've been taking apart and analyzing the sysctl(8) program to gain a

It's using an oid of 0 and 2 to get something, then it comes up with 440
and then a sequence of numbers that are incrementing in a peculiar
pattern.

sysctl(8) uses undocumented interfaces to a) enumerate the nodes in
the sysctl tree and b) obtain the name of a node, given its OID.

So, my question is, how do I walk the tree to get the PnP info for all
the devices in the system?
