LabVIEW
Vector XL Driver - LabVIEW wrapper
That's something you have to take up with the vectorXL manufactorer. If they can't or don't want to give you that information, how should we be able to do that?
Well that library was created using the Import Library Wizard (ILW) and thankfully reviewed and hand modified afterwards. While the ILW despite its name isn’t a magic tool, the created VI’s are a nice starting point for a real driver but generally at least suboptimal, often almost useless for an average LabVIEW user without deep C programming language knowledge, and regularly simply crashy, it does create a wrapper for every function it can parse in the header file that is also present in the DLL. So that is why it’s present in that library. Without proper documentation in the manual it is anyones guess if the actual VI implementation is correct and its use simply impossible. If I had created that library I would probably have removed that wrapper for this reason.
Maybe the most interesting question would be why you believe that you would need this function. According to the documentation from TroyK on his page for this library, the DLL driver can be used without any license. It seems to be the higher level software such as their Test Software and their own LabVIEW driver that require a specific license but the driver should be working without that.
After all you bought the hardware and it would be a bit strange if you had to buy an extra license to even be able to access that hardware. The old DOS days where you could sell a hardware with a register description so that everybody could himself/herself try to work out what register addresses to tickle in which order and what values and be done are long gone. Without a proper device driver and user space access library even the most expensive hardware board is simply as valuable as a brick nowadays.
