First, I received a prompt answer to yesterday's query.  Today's
question is this:

I have a file that has protection 777.  This is a publically accesible
database file.  Their are two users, A and B.  A starts the database
and [the program] uses lockf to lock the database file.  B starts up
the database and obviously can not get the lock.  Is there some way to
imform B that it is A who has the lock?
