Only one respondent to my question ('What happened to Dennis Ritchie's
replacement for the tty driver?') had firm enough information that they
didn't mind their name being associated with it in public... This
respondent said:
The stream character IO system is alive, and is being wondered
over by the unix development lab. I would not hazard a guess
as to what system it will appear in. No lawyers had a chance
to nix it for any BSD, since it wasn't offered to them (either
of "them").
...
I don't think I said anything secret. Further non-secret
facts: the system run by our organization is known as the
Eighth Edition system, usually solecized to V8, but is
certainly not going to be distributed under that name or any
other.
The stream, or coroutine, IO system is a design for writing IO
processing modules. At the moment, there are two modules for
doing tty handling; one is like v7 and the other is like the
UCB "new tty" stuff.
A paper describing the details is scheduled for publication in
a new special BSTJ issue on Unix to appear next year. (However
the journal will doubtless have a new name, because will be no
Bell System next year.)
Dennis
Since the stream IO system was not offered to Berkeley, I assume that
the 'descriptor wrapping' proposals for 4.2/3 BSD are distinct and
would contain no Eighth Edition code.
I stand corrected of my paranoia about lawyers: Mark Horton's new
curses package is unavailable as a result of the decision of a USG
department head, not due to lawyers.
Does anyone else have any information (or misinformation) to add?
