The LabVIEW dlls are there strictly for the VIs that call them, so you don't really need to know what the dlls do in order to use them. You should just call the VI that uses them, which is a safer method. If you want to call the DLL from another application, you can always create a LabVIEW wrapper DLL that uses the VIs that call the lvanlys.dll. Then, your application can call the wrapper DLL and you would be set.
