Re: Getting the device name from a struct tty *

[Brian Buhrow <buhrow%nfbcal.org@localhost>]

        hello.  You should be able to find what you need by getting the unit
number from the dev_t element, there's a macro for that in C, but I don't
know about Lua.  Alternatively, you should be able to parse it from the
dev_xname field of one of the fields of the struct dev you're passed.  (I
think the name of the device is somewhere in there too and can be combined
with the unit value referred to above.)
