       al_install_haptic - Allegro 5 API


              #include <allegro5/allegro.h>

              bool al_install_haptic(void)


       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(3alleg5).
       On some platforms, such as DirectInput under Windows, al_install_haptic(3alleg5) will only
       work  if at least one active 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_haptic(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.
