That's true enough if you're interested in the abstract structure of the overall MIB tree, but not if you want to know about the data returned by a particular agent. The code above is looking at how many MIB objects (not instances) the *client* knows about. This is purely controlled by which MIB files are loaded by that client. It's got nothing to do with what information a particular agent might return. The agent might well support some values that the client doesn't have MIBs for (so wouldn't be included in the tp->child_list). And the agent almost certainly won't implement everything that the client knows about. And of course, the agent is returning *instances*, not objects, so might return several values relating to a single MIB (table) object. The only way to discover the children of a given MIB root as far as the *agent* is concerned, is to walk that subtree, and parse the results.
