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.
