) | [virtual] |
A variant on seekoff() to implement seeking within a stream.
The MSDN Library claims that it is only necessary to redefine seekoff(), and not seekpos() as well, as the default implementation of seekpos() is supposed to map to seekoff() exactly as I am doing here; but in fact it must do something else, because seeking didn't work on Windows until I redefined this function as well.
