keyboard_clearstate(3)	      Svgalib User Manual	keyboard_clearstate(3)

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. Call‐
       ing 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 con‐
       trol of the console.
