NAME
       al_get_haptic_from_joystick - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              ALLEGRO_HAPTIC *al_get_haptic_from_joystick(ALLEGRO_JOYSTICK *dev)


DESCRIPTION
       If the joystick has haptic capabilities, returns the associated haptic
       device handle.  Otherwise returns NULL.  It's necessary to call this
       again every time the joystick configuration changes, such as through
       hot plugging.  In that case, the old haptic device must be released
       using al_release_haptic(3).

SINCE
       5.1.8

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