User Definable Events


Recommended Posts

I'm in the habit of using queues and occurrences to communicate between different parts of an app- typically just using a handful of occurrences for simple things such as shutdown (since if a VI reads an occurrence for this it's much more portable than if it reads a global).

One advantage of events is that they are non-polling. I've always assumed this has always applied to occurrences and queues. Does anyone know for sure that these are non-polling? If not, user defined events may now be a better option.

Craig,

Queus, Notifiers, and occurrences are all non-polling, unless you set the timeout to something other than "-1". Same thing with the event structure, which also has a timeout. The trick is to make the consumer of your event non-polling (with an infinite timeout) and then destroy the queue/notifier or send a user-defined "exit" event to the event structure get it to return/execute so that you can shutdown.
