/*
* include/linux/vt_buffer.h -- Access to VT screen buffer
*
* (c) 1998 Martin Mares <mj@ucw.cz>
*
* This is a set of macros and functions which are used in the
* console driver and related code to access the screen buffer.
* In most cases the console works with simple in-memory buffer,
* but when handling hardware text mode consoles, we store
* the foreground console directly in video memory.
