Memory mapping on 4.2 or Ultrix 1.1.

[Stefan Brandle]

I am trying to get multiple copies of a program to use the same memory
area.  The documentation for 4.2 describes some rather nice memory
management facilities, then adds in a footnote that all but two of
those mentioned is not implemented.

One possibility is to set up sockets with some sort of protocol for
exchanging infomation on values of variables, etc, but this would be
a rather slow and messy business.  An alternative is to write the stuff
into common files.  This would also be slow and messy.

Any way of doing memory mapping, controlling sharing of memory, etc. for
programs that would have to share a lot of information.

Thanks for any suggestions,
