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

NAME

       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.

NAME

       install_keyboard - Installs the Allegro keyboard interrupt handler.

SYNOPSIS

       #include <allegro.h>

       int install_keyboard();

DESCRIPTION

       Installs  the  Allegro keyboard interrupt handler. You must call this before using any of the keyboard input routines. Once you have set up
       the Allegro handler, you can no longer use operating system calls or C library functions to access the keyboard.

       Note that on some platforms the keyboard won't work unless you have set a graphics mode, even if this  function	returns  a  success  value
       before  calling set_gfx_mode. This can happen in environments with graphic windowed modes, since Allegro usually reads the keyboard through
       the graphical window (which appears after the set_gfx_mode call). Example:

	  allegro_init();
	  install_timer();
	  install_keyboard();
	  /* We are not 100% sure we can read the keyboard yet! */
	  if (set_gfx_mode(GFX_AUTODETECT, 640, 480, 0, 0) != 0)
	     abort_on_error("Couldn't set graphic mode!");

	  /* Now we are guaranteed to be able to read the keyboard. */
	  readkey();

RETURN VALUE

       Returns zero on success, or a negative number on failure (but you may decide not to check  the  return  value  as  this	function  is  very
       unlikely to fail).
