[Click] Stupid question, handler example...

[Eddie Kohler]

Sure; take a look at RED.  RED either looks for upstream elements that match a 
spec (i.e., they're Queues), or can take a list.  Here's how it handles the 
list (which is a cpArgument called queues_string).

	Vector<String> eids;
	cp_spacevec(queues_string, eids);
	_queue_elements.clear();
	for (int i = 0; i < eids.size(); i++)
	    if (Element *e = router()->find(eids[i], this, errh))
		_queue_elements.push_back(e);
	if (eids.size() != _queue_elements.size())
	    return -1;
