three_finger_flag(3)            Allegro manual            three_finger_flag(3)

NAME
       three_finger_flag - Flag to deactivate the emergency exit key
       combination. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       extern int three_finger_flag;

DESCRIPTION
       The DJGPP keyboard handler provides an 'emergency exit' sequence which
       you can use to kill off your program. If you are running under DOS this
       is the three finger salute, ctrl+alt+del. Most multitasking OS's will
       trap this combination before it reaches the Allegro handler, in which
       case you can use the alternative ctrl+alt+end. If you want to disable
       this behaviour in release versions of your program, set this flag to
       FALSE.
