getting erl_interface C program to reply to net_adm:ping/1

[Peter-Henry Mander]

Hi Gurus,

I'm locking horns with erl_interface C libraries, and so far I've 
managed to get most thing to work, thanks to the excellent 
documentation. But I've stumbled on net_adm:ping/1. I can receive the 
{is_auth,NodeName} message, but since I don't know how to reply, the 
pinging end never gets a 'pong' back and just dumbly sits there.

What is the appropriate answer to a 'ping', when using erl_interface?

Also, what is involved in making a 'C' node behave like a visible node 
instead of a hidden one?

Pete.
