Hi, I'm trying to figure out the best way to handle the following situation. There are two processes, A, and B. A is a daemon process that performs a select, and then slowly iterates over the results, performing updates along the way. It is possible that interactive process B comes along, and wants to change the data that A is working with. B should not 1) hang or 2) fail (it's interactive, and in this case the user is always right). It's not optimal, but it would be ok if A failed - indeed, it would be better than if it kept working with the (now incorrect) data that it pulled from the select prior to the user's intervention. Thoughts? Thankyou for any insight you can send my way! -- David N. Welton - http://www.dedasys.com/davidw/ Linux, Open Source Consulting - http://www.dedasys.com/
