virtual pos_type seekoff( off_type off, ios_base::seekdir dir,
Sets the position indicator of the input and/or output sequence relative to some other position.
seekoff(off, dir, which) of the most derived class
2) The base class version of this function has no effect. The derived classes may override this function to allow relative positioning of the position indicator.
|off||-||relative position to set the position indicator to.|
|dir||-|| defines base position to apply the relative offset to. It can be one of the following constants:
|which||-|| defines which of the input and/or output sequences to affect. It can be one or a combination of the following constants:
Not all combinations of parameters are valid. All the sequences denoted by
which must match the sequences denoted by the instantiation of the basic_streambuf. When modifying both the input and output sequences together,
dir may only be beg or end. Otherwise, the positioning operation fails, and pos_type(off_type(-1)) is returned.
 Return value
1) The return value of
seekoff(off, dir, which)
2) The resulting absolute position as defined by the position indicator. The base class version returns pos_type(off_type(-1)).
