Great. Yes, that was it, thank you very much.

However, I wonder exactly how I could have found this out without recourse
to asking the reflector (and relying on your intelligent guesswork)...

How? I have installed apt-file, but I don't see how it helps.

The apt-file man page leads me to believe that "apt-file search
getaddrinfo" ought to be helpful, but it's not :-( It returns nothing:

----

[H:~] apt-file search getaddrinfo
[H:~]

So what command would find the package that contains the getaddrinfo man
page for me? I'm not trying to be denser than usual; I really can't guess.

For my edification, what would you search for there? I had tried that (and
just tried it again), and I couldn't guess what I might want to search for.

(And I'm not also sure what you mean by "if I thought it was correct"; if
you thought what was correct?)
