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.
