GetCalibrationTableEntry (7)Description
This function gets the calibration parameters for one entry in the
internal calibration table. There are two retrieval methods, using either
a calibration table index, or a search for a BIOS video mode. If a BIOS
video mode is searched for, and no entry is found in the table that
corresponds to the BIOS video mode, the default calibration entry is
returned. If no calibration entry is marked as the default, the first
calibration entry (calibration table index 0) is returned.
