I need some help trying to get shmget to work on a Sun 3/60 running SunOS
4.0.3.  This same program runs just fine on a Sun 3/50 running SunOS 3.5.
I don't see any difference in the documentation between the two systems,
however something has changed.

I get the following as an error message:

$ a.out
shmget failed: Invalid argument

If you have any ideas I'd appreciate hearing from you.

Thanks for your help!
