NAME

       keyboard_update, keyboard_waitforupdate - process raw keyboard events

SYNOPSIS

       #include <vgakeyboard.h>

       int keyboard_update(void);
       void keyboard_waitforupdate(void);

DESCRIPTION

       These  routines	check  the  keyboard  buffer  for  any	raw  keyboard  events and do the necessary updates to the internal buffers of key-
       board_clearstate(3) and keyboard_keypressed(3).

       When there are no such events, keyboard_update() returns 0 immediately (non-zero else) whereas keyboard_waitforupdate()	blocks	and  waits
       until an event occurs.

       vga_waitevent(3) allows to wait for keyboard and other events at the same time.
