That'll work....

you can also ask cdevsw_add() to ASSIGN you a major number and tell you
what
it chose.. (in the cdevsw entry)
(this of course is most useful in the DEVFS case)

you ARE adding a DEVFS entry for it are you not?
 :)

otherwise people running on DEVFS won't be able to use it ..
(it's very simple to use..see any other driver..
(and there is a man page for the calls in man 9)
