NAME

6       al_install_haptic - Allegro 5 API
7

SYNOPSIS

9              #include <allegro5/allegro.h>
10
11              bool al_install_haptic(void)
12

DESCRIPTION

14       Installs  the  haptic  (force feedback) device subsystem.  This must be
15       called before using any other haptic-related functions.   Returns  true
16       if  the haptics subsystem could be initialized correctly, false in case
17       of error.
18
19       For  portability  you  should  first  open  a  display  before  calling
20       al_install_haptic(3).   On  some  platforms,  such as DirectInput under
21       Windows, al_install_haptic(3) will only work if  at  least  one  active
22       display  is available.  This display must stay available until al_unin‐
23       stall_haptic(3) is called.
24
25       If you need to close and reopen your active display for  example,  then
26       you  should call al_uninstall_haptic(3) before closing the display, and
27       al_install_haptic(3) after opening it again.

33              port  for  all the exposed features across all of the platforms.
