There is an interesting paper that Dennis Ritchie and Dave Presotto wrote, “Interprocess
Communication in the Ninth Edition Unix System”
(https://www.bell-labs.com/usr/dmr/www/ipcpaper.html
<https://www.bell-labs.com/usr/dmr/www/ipcpaper.html>).
This appears to be an update of a paper that they wrote in 1985, “Interprocess
Communication in the Eighth Edition Unix System”. This earlier paper is hard to find.
Anybody on this list who has it on hand?

It's supposed to be in the proceedings of the June, 1985 Usenix conference.
If anyone has a hard copy, and the full paper is in there, it should be
scannable.

New subject: About the history of cfree()
Hello,
does anyone remember details on how the cfree() function ended to <stdlib.h>
of various systems?
From the only available documentation I could easily
find [1], I'd reckon it
came from SCO's malloc implementation that tried
to conform to Intel's i386
iBCS. But almost all other systems wrapped it to free(). Interestingly, it
seems that also SunOS 4.0 (1988) used the free()-wrapper. So was the
3-parameter cfree() only used in SCO XENIX 386 (1987) and the like [2]?
Anyways, a small but interesting detail, and I suppose a good example on the
developments that led to ANSI C.
