Hello all, and thanks for your attention!
I'm trying to understand the messaging tools in System V UNIX, and I've
written a program to execise these things. However, I seem to have a
problem allocating message queues after debugging for awhile. Here's what
happens:
I start my program, and messages begin to fly all over,
Everything works fine, I exit normally, no problem.
Now if I start my program, allow messages to start passing
out and about, and then crash my program, I think it leaves
the message queue still assigned to my program. After doing this
a few times, I seem to run out of queues, and my program hangs
while trying to allocate a new queue. This hanging problem
persists until the machine is re-booted.
Obviously, I can't go around booting a machine with tons of users, I
wouldn't last too long! :-) So my question is (finally):
Is there any way to find out what queues are assigned to me or
my programs, and how can I clean up queues left over from
a premature program exit?
Thanks again for sticking with me this far, I hope someone can help!!
tom..

Use ipcs to display the IPCs currently being used by your system. Use ipcrm to remove the IPCs that you no longer need. See the manual pages for correct syntax. -- +-----------------------------------------------------------------------+ | Conor P.
