I hope I'm guessing the miscommunication here correctly.
The routine does exist. It's called internally to translate stuff
between K5 and K4. The reason to look at the man page for it isn't
so you can use the function directly.
The reason to look at the man page is because it tells you how the
conversion is done. It also tells you some stuff about what you can
put in /etc/krb5.conf to control how the translation is done. THAT
is the reason to look at the page.
