It's the responsibility of the application to query the screen size
before doing full-screen I/O. If the application only uses line mode
then VTIOC will handle the screen geometry automatically.

TPUT is certainly the most common interface to VTIOC.

Yes, and the application needs the screen width in order to convert
row/column to buffer address.
