is it possible to get the serial number from external C++ code?

Hi,

I have a C++ library called by a CLF in the LabVIEW RT from my cRIO. I am trying to use the cRIO serial number in my C++ code for licensing purposes. Is it possible to get the cRIO serial number using the C++ API?

I found information on how to do this from LabVIEW itself (http://digital.ni.com/public.nsf/allkb/74924FEE303440998625727D005197FA), but it would be really helpful to be able to do it from the C++ code.

Thanks in advance!
