First correction, but I'm sure you have figured that out already, just not written explicitly in your question:

So if I understand you right, if I have three CLNs in my hierachy, with all of them having the abort callback configured, the callback would be called three times.

And no, unfortunately the case is not that simple:

You have to consider reentrant (or clone VIs too). For any instance of a VI containing such a CLN your callback will be called once. The according parameter is not called "instance data pointer" for nothing!

Great!

So then to work
