information hiding

[jcurl]

I have a general question that didn't show up in a search. I'd like to implement information hiding for some of my VI's. LabVIEW seems to do this nicely with refnums.

For the drivers I'm writing, I need to keep state. Easily done with Clusters. However, I want to hide the contents of the cluster to the main application so they're forced not to use anything within the Cluster. It will also reduce the visible size considerably for some of the other typedefs and state machines I have.

So far, I can convert them to refnums and back but this is a lot of work. is there something simpler?

Hi there

have you thougt about LV classes? This is maybe the best way to hide private data for calling applications.
