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.
