This function parses a calibration file (produced by the comedi_calibrate or comedi_soft_calibrate programs) and returns a pointer to a comedi_calibration_t which can be passed to the comedi_apply_parsed_calibration() or comedi_get_softcal_converter() functions. When you are finished using the comedi_calibration_t, you should call comedi_cleanup_calibration() to free the resources associated with the comedi_calibration_t.
The comedi_get_default_calibration_path() function may be useful in conjunction with this function.
