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 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.
