16 These routines check the keyboard buffer for any raw keyboard events
17 and do the necessary updates to the internal buffers of key‐
18 board_clearstate(3) and keyboard_keypressed(3).
19
20 When there are no such events, keyboard_update() returns 0 immediately
21 (non-zero else) whereas keyboard_waitforupdate() blocks and waits until
22 an event occurs.
23
24 vga_waitevent(3) allows to wait for keyboard and other events at the
25 same time.
