Re: User space

In all the samples I have seen, the user space was used to hold the output from an API.

In my case, I have several user entering transacctions, and I want to know who was the one that finsh the last transaction up to now, and provide that info to everybody else. someting like:
____________________________________

Last completed transaction by:  USER7
____________________________________

Refresh may show somebody else, or the same user.
If two users complete a transaction at the same time, any one of them should appear.

It is almost like a STACK, where I can only see the TOP. The difference is I only care about the TOP, and I want to discard the rest.
A field from the user space as output on the screen does the trick. The time on screen shows when that was valid, refresh will update the time and the user. It is working the way I want it, it was easy to program.

I'm still curious to know if there is a better way to do it.

IMHO, the problem here is that you're trying to use user spaces for
interprocess communications, and that's not what they're designed for.

Either use data queues to synchronize access to the user space, or just
use data queues to pass the data...

wouldn't we derive the same anti-lock capabilities using the ALCOBJ
