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 hap‐
       tic-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(3alleg5).  On some plat‐
       forms,  such  as DirectInput under Windows, al_install_haptic(3alleg5) will only work if at least one ac‐
       tive display is available.  This  display  must  stay  available  until  al_uninstall_haptic(3alleg5)  is
       called.

       If  you  need to close and reopen your active display for example, then you should call al_uninstall_hap‐
       tic(3alleg5) before closing the display, and al_install_haptic(3alleg5) 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.
