       keyboard_update, keyboard_waitforupdate - process raw key-
       board events

       #include <vgakeyboard.h>

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

       These routines check the keyboard buffer for any raw  key-
       board  events and do the necessary updates to the internal
       buffers  of   keyboard_clearstate(3)   and   keyboard_key-

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

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