How do I know what "Call by Ref #X" means in the VI Profiler?

[rothloup]

When using the VI profiler, I sometimes see this underneath a VI when I double-click on the name to expand the timing details:  (see screenshot)

"...Call by Ref. #2"

What does that mean?

I have a code snippet attached showing the particular VI highlighted in the screenshot.

Note that I am using dynamic dispatch VIs to call the various functions.  I have a feeling that is the "call by ref", but how do I know which one is #1, #2, etc?

Thanks for any help.

Hi Rothloup,

The easiest way to identify the VI is to right-click on the instance (e.g. Ref #2) and select "Find Calls in this VI".

This will highlight that specific VI on the block diagram allowing you to reference it. For me, they appear when I am using a Call by Reference node.

Perfect, thank you!
