These member functions are seekg ("seek get") for istream and seekp ("seek put") for ostream.
The seek direction can be ios::beg (the default) for positioning relative to the beginning of a stream, ios::cur for positioning relative to the current position in a stream or ios::end for positioning relative to the end of a stream.
// position to the nth byte of fileObject (assumes ios::beg) fileObject.seekg( n ); // position n bytes forward in fileObject fileObject.seekg( n, ios::cur ); // position n bytes back from end of fileObject fileObject.seekg( n, ios::end ); // position at end of fileObject fileObject.seekg( 0, ios::end );
