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.
