SYNOPSIS

10       #include <allegro.h>

13       void set_leds(int leds);

DESCRIPTION

16       Overrides the state of the keyboard LED indicators. The parameter is  a
17       bitmask containing any of the values KB_SCROLOCK_FLAG, KB_NUMLOCK_FLAG,
18       and KB_CAPSLOCK_FLAG, or -1 to restore the default behavior. Example:
19
20          /* Cycle led indicators. */
21          set_leds(KB_SCROLOCK_FLAG);
22          rest(1000);
23          set_leds(KB_CAPSLOCK_FLAG);
24          rest(1000);
25          set_leds(KB_NUMLOCK_FLAG);
26          rest(1000);
27          set_leds(-1);
28
29       Note that the led behaviour cannot be  guaranteed  on  some  platforms,
30       some leds might not react, or none at all. Therefore you shouldn't rely
31       only on them to communicate information to the user, just  in  case  it
32       doesn't get through.
