I try to control keyboard LEDs with ioctl calls but they don't work.
Despite ioctl returns success, LEDs will not turn on/off. The same code
works fine on Linux (with a change of <machine/console.h> to
<linux/kd.h>. Is it a bug or feature of FBSD? How to make it work?

The code is following:

#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#include <sys/ioctl.h>
#include <machine/console.h>

main(int argc, char *argv[]) {
  char leds;

  if ( ioctl( 0, KDGETLED, &leds ) ) {
      fprintf(stderr,"Can't get leds\n");
      exit(1);
  }
  if ( ioctl( 0, KDSETLED, leds | LED_CAP ) ) {
      fprintf(stderr,"Can't set leds\n");
      exit(1);
  }
  printf("Caps lock should glow\n");
  getchar();
  ioctl( 0, KDSETLED, leds );
  exit(0);
}

Sincerely,
Alex
