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).
