basic_streambuf::pubseekpos

Calls seekpos, a protected virtual function that is overridden in a derived class, and resets the current pointer position.

pos_type pubseekpos(
   pos_type _Sp,
   ios_base::openmode _Which = ios_base::in | ios_base::out
);

Parameters

• _Sp
  The position to seek for.

• _Which
  Specifies the mode for the pointer position. The default is to allow you to modify the read and write positions.

Return Value

The new position or an invalid stream position. To determine if the stream position is invalid, compare the return value with pos_type(off_type(-1)).

Remarks

The member function returns seekpos(_Sp, _Which).
