[comp.os.xinu] what is xinu

evan@ndcheg.UUCP (Evan Bauman) (11/01/87)

Don't mean to be a drag, but could someone enlighten me as to what
exactly 'xinu' is?  I'm aware of the Mt. Xinu UNIX  distribution, but
it's hard to believe that Purdue is distributing this for Sun 3's at
the cost of only $100.

Please reply by e-mail.  Thanks.

Xinu is a small, elegant operating system described in a 2-volume set of
textbooks by Douglas Comer:

		Opeating System Design (Vol I)
		The Xinu Approach
		Prentice Hall, 1984

		Operating System Design (Vol II)
		Internetworking with Xinu
		Prentice Hall, 1987

Among the features are: hierarchical design, rich functionality, novel
implementations of system components, and implementation in C that makes
it portable.

Although Xinu contains many ideas found in UNIX, it is definitely
NOT compatible in any sense.
