Hi all,
I just received a query: did SunOS 3 have a working mmap(2)? My
vague memory says no, but I don't have access to a 3.5 box any more to
find out. Can anybody help out here?
Warren

I don't know. But you may ask Peter Koch, the director of the Sun3 Zoo:
http://www.sun3zoo.de/
Peter knows everything about Sun 3 hardware and has some in deep
knowledge of SunOS.

I've just asked someone who knows, and he elaborated my very vague
memory: yes it did, and in fact there was mmap right back, and beyond,
the start of SunOS. *But* it only mapped devices, particularly
framebuffers, where it was obviously very useful. SunOS 4 had a
fully-fledged mmap.
I am fairly sure that 4.2BSD had manual pages for mmap, but it didn't
work.

Wasn't some mmap like functionality a central concept of MULTICS long
bevore UNIX was born? (I should read that article about MULTICS on the
web again.)

... mostly for implementing shared libs. (?)

AFAIK BSD got a mmap with the MACH-VM in 4.3BSD-Reno. The old VAX-VM had
no mmap.
