       keyboard_update, keyboard_waitforupdate - process raw keyboard events


       #include <vgakeyboard.h>

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


       These  routines  check  the keyboard buffer for any raw keyboard events
       and  do  the   necessary   updates   to   the   internal   buffers   of
       keyboard_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.
