Summary: But you can lseek() on lots of character special files ...


I seem to recall that you can seek on the following character special files
(or your local version thereof)
	/dev/mem
	/dev/kmem
	/dev/rdsk/*
I think the only things that leaves out are raw tapes and ttys.  Did anyone
not really know this?  Of course you can't seek on the WONDERFUL new
pseudo devices like /dev/error, /dev/prf, ad nauseum.  But then, REAL
programmers still use Version 6 or Version 7 ...
