As far as C is concerned, stdout is nothing more than a byte stream. That stream could be attached to a CRT (or flat screen), or it could be attached to a hardcopy device like a teletype or even a sheet-fed printer. Calling rewind on the stream won't necessarily be reflected on the output device, because it may not make any sense in context of that device; think about what rewinding would mean on a hardcopy terminal or a sheet-fed printer.

C does not offer any built-in support for display management, so you'll have to use a third-party library like ncurses.
