/*
 * conio.h
 *
 * Ullrich von Bassewitz, 06.08.1998
 *
 *
 * This is the direct console interface for cc65. I do not like the function
 * names very much, but the first version started as a rewrite of Borlands
 * conio, and, even if the interface has changed, the names did not.
 *
 * The interface does direct screen I/O, so it is fast enough for most
 * programs. I did not implement text windows, since many applications do
 * not need them and should not pay for the additional overhead. It should
 * be easy to add text windows on a higher level if needed,
 *
 * Most routines do not check the parameters. This may be unfortunate but is
 * also related to speed. The coordinates are always 0/0 based.
