If you would go this way, I would prefer an enum as parameter, because it's easier to use and the code is easier to
understand. You don't have to remember if true is left or right. :)
"Step" would than have two parameters, the enum and an uint.
Well, I guess especially with the Step() function it could have been nice
to have the sign indicate the direction. But then again VDR itself probably
isn't going to use Step() with anything else but '1', so
enum ePositionerDirection { pdLeft, pdRight };
virtual void Step(ePositionerDirection Direction, uint NumSteps = 1);
should do just fine...
