key_led_flag(3alleg4)						  Allegro manual					     key_led_flag(3alleg4)

key_led_flag - Flag to prevent the keyboard LEDs from being updated. Allegro game programming library. SYNOPSIS
#include <allegro.h> extern int key_led_flag; DESCRIPTION
By default, the capslock, numlock, and scroll-lock keys toggle the keyboard LED indicators when they are pressed. If you are using these keys for input in your game (eg. capslock to fire) this may not be desirable, so you can clear this flag to prevent the LED's being updated. SEE ALSO

set_leds - Sets the state of the keyboard LED indicators. Allegro game programming library. SYNOPSIS
#include <allegro.h> void set_leds(int leds); DESCRIPTION
Overrides the state of the keyboard LED indicators. The parameter is a bitmask containing any of the values KB_SCROLOCK_FLAG, KB_NUM- LOCK_FLAG, and KB_CAPSLOCK_FLAG, or -1 to restore the default behavior. Example: /* Cycle led indicators. */ set_leds(KB_SCROLOCK_FLAG); rest(1000); set_leds(KB_CAPSLOCK_FLAG); rest(1000); set_leds(KB_NUMLOCK_FLAG); rest(1000); set_leds(-1); Note that the led behaviour cannot be guaranteed on some platforms, some leds might not react, or none at all. Therefore you shouldn't rely only on them to communicate information to the user, just in case it doesn't get through. SEE ALSO
