pos_type pubseekpos( pos_type pos,

virtual pos_type seekpos( pos_type pos,

                          ios_base::openmode which = ios_base::in | ios_base::out);

Sets the position indicator of the input and/or output sequence to an absolute position.

1) Calls seekpos(pos, 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 absolute positioning of the position indicator.


pos - absolute position to set the position indicator to.
which - defines which of the input and/or output sequences to affect. It can be one or a combination of the following constants:
Constant Explanation
in affect the input sequence
out affect the output sequence

Return value

1) The return value of seekpos(pos, which)

2) The resulting absolute position as defined by the position indicator. The base class version returns pos_type(off_type(-1)).
