SCO Unix MMDF/ELM 2.3PL11 problem

[John R. MacMillan]

I mailed this to the original poster, but I thought it might be of
interest to others.

The answer should probably be in an FAQ.  Past distributions of SCO
MMDF have had the permissions set wrong, you should run:

/usr/mmdf/bin/checkup -p

and fix what it tells you to.  (Actually, it will probably say certain
directories should be 707, but the group permissions don't matter so
777 is fine.)

Another couple of notes for elm: you should have elm use the fcntl()
locking, as that's how MMDF locks.  Also, the locking code in elm that
does the fcntl() does not expect EACCES if it can't get the lock,
which is what SCO returns (as per the SVID), so you may want to add
that in.
