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(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.
