Unfortunately, we don't have any C/C++ driver for these modules, but they should be accessible via C/C++ if you first create a FPGA bitfile in LabVIEW that exposes the necessary channels.
Help and tutorials from NI:

This is essentially the same FPGA you'll need to build if you are going to use LabVIEW to access the channels.
