Enumeration Lists

To avoid name collisions on defines, integer values have been captured as enumeration lists. The set of valid values from an enumeration list varies with the application. The detailed method descriptions describe the valid or possible values for the specific use. The following enumeration lists are provided in the UMSTuner base class and are referenced in both the UMSRadioTuner and UMSTVTuner objects.

enum ReturnCode { 
   Success,
   Failure,
   NotSupported,
   InvalidArgument,
   NullPointer,
   UnsupportedFormat,
   DeviceNotOpen,
   DeviceError,
   NotCompleteTryAgain
   };

enum OnOff {
   Off,
   On
   };

enum TuneStatus { 
   Tuned,
   NotTuned, 
   Undefined, 
   TunedMono, 
   TunedStereo 
   };

enum TunerMode { 
   Cable, 
   Air 
   };

enum Direction { 
   Up, 
   Down 
   };

enum VideoFormat { 
   NTSC, 
   PAL,
