al_install_haptic(3)                                      al_install_haptic(3)

NAME
       al_install_haptic - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              bool al_install_haptic(void)


DESCRIPTION
       Installs the haptic (force feedback) device subsystem.  This must be
       called before using any other haptic-related functions.  Returns true
       if the haptics subsystem could be initialized correctly, false in case
       of error.

       For portability you should first open a display before calling
       al_install_haptic(3).  On some platforms, such as DirectInput under
       Windows, al_install_haptic(3) will only work if at least one active
       display is available.  This display must stay available until
       al_uninstall_haptic(3) is called.

       If you need to close and reopen your active display for example, then
       you should call al_uninstall_haptic(3) before closing the display, and
       al_install_haptic(3) after opening it again.

              [Unstable API]: Perhaps could be simplified due to limited
              support for all the exposed features across all of the
              platforms.  Awaiting feedback from users.
