Re: [ns] Re: nodeid from c++

["B. Scott Michel" <scottm@CS.UCLA.EDU>]

One can find the node's id from C++, if you are an agent by:

    cout << Address::instance().get_nodeaddr(addr());

But I agree with this message, notably, you probably DON'T want to set the
node's ID from C++.

This returns the node's ID, which may be a hierarchical address if you have
that turned on and "looks funny". Not to despair however, Address has a
method for pretty printing that too if needed.
