I have a seekable iostream device with the tag set to :

     typedef boost::iostreams::input_seekable catagory;

If I have not defined the functions get and seek, it will not compile,
which is expected, so far so good.
But when I called it like this :

          mydevice test("somefile.txt");

          boost::iostreams::stream<mydevice> buf(test);

          buf.seekg(0);

it never enters my seek function, which I would expect. I am sure the
solution must be obvious. Any pointers here ?
