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.
