Hello Sarah,
I do not have enough familiarity with Labview to resolve this I believe. My co-worker is the one familiar with Labview. He is on vacation and will be back next week. Email justin@teplus.com and he will get back to you.
Some notes: The function should take a pointer to an array very similarly to the get sweep functions. Labview might treat integer arrays differently. You can see this function in action if you start the Spike software with no devices attached, then plug in both devices and go to the File -> Connect menu. You should see a list of your devices which is generated with the GetSerialNumberList function. The serial numbers will not appear if the devices have been opened with the saOpenDevice function. If either parameter is null then the function will return early as well.
Regards,
A.J.
