Hi obrien,
Those functions should all be available in NI-DAQmx C API. If you can get that working in CVI 5.5, then you should be good to go.
Most of those functions can be found in the NI-DAQmx C Reference Help (Start >> Programs >> National Instruments >> NI-DAQ >> NI-DAQmx C Reference Help) under the section NI-DAQmx C Functions >> Advanced Functions >> Calibration.
Thanks!
