NAME

       keyboard_clearstate - reset the state of all keys when in raw keyboard mode

SYNOPSIS

       #include <vgakeyboard.h>

       void keyboard_clearstate(void);

DESCRIPTION

       When  in  raw keyboard mode, svgalib receives press and release events from the kernel and
       keeps track which keys are currently  pressed.  Calling  keyboard_clearstate()  sets  this
       information  to  all keys released. You can use this for cleanup at certain places in your
       program. In addition svgalib resets the states of all keys when a VC switch occurs because
       it does not know the current state of keys when it regains control of the console.
