Borrow---or better, buy---a copy of Marc Rochkind's great book
_Advanced_Unix_Programming_, 1985 by Prentice-Hall.  Look at the
"Shared Memory" section on pages 192 through 198, and read the
"Portability" section on page 206.  Not only does he explain what it
does, he gives you real code that you can use in your programs.

If you have an HP-UX Series 800 machine somewhere nearby, find out
where they keep its manuals.  HP bundles a copy of Rochkind's book
with every Series 800.
