From /usr/src/contrib/libio/iostream.cc:

ostream& ostream::seekp(streampos pos)
{
    pos = _strbuf->pubseekpos(pos, ios::out);
    if (pos == streampos(EOF))
        set(ios::badbit);
    return *this;
}

ostream& ostream::seekp(streamoff off, _seek_dir dir)
{
  streampos pos = _IO_seekoff (_strbuf, off, (int) dir, _IOS_OUTPUT);
  if (pos == streampos(EOF))
    set(ios::badbit);
  return *this;
}

Are you sure you're doing it right?
