#include "stdio.h"
#include "X11/Xlib.h"
#include "X11/keysym.h"
#include "time.h"
Display *display=NULL;
unsigned int keycode;
int main()
{
display = XOpenDisplay(NULL);
keycode = XKeysymToKeycode(display, XK_Caps_Lock);
printf ("\npressed\n");
XTestFakeKeyEvent(display, keycode, True, CurrentTime);
XFlush(display);
printf ("\nreleased\n");
XTestFakeKeyEvent(display, keycode, False, CurrentTime);
XFlush(display);
sleep(3);
/* type something here */
printf ("\npressed\n");
XTestFakeKeyEvent(display, keycode, True, CurrentTime);
XFlush(display);
printf ("\nreleased\n");
XTestFakeKeyEvent(display, keycode, False, CurrentTime);
XFlush(display);
sleep(3);
return 0;
}
Remplacer "" -s par <> pour les fichiers d'en-tête. et compiler en utilisant main.c gcc -lX11 -lXtst
