NAME
SDL_HINT_JOYSTICK_HAPTIC_AXES - A variable containing a list of devices and their desired number of
haptic (force feedback) enabled axis.
SYNOPSIS
#include <SDL3/SDL_hints.h>
#define SDL_HINT_JOYSTICK_HAPTIC_AXES "SDL_JOYSTICK_HAPTIC_AXES"
DESCRIPTION
The format of the string is a comma separated list of USB VID/PID pairs in hexadecimal form plus the
number of desired axes, e.g.
0xAAAA/0xBBBB/1,0xCCCC/0xDDDD/3
This hint supports a "wildcard" device that will set the number of haptic axes on all initialized haptic
devices which were not defined explicitly in this hint.
0xFFFF/0xFFFF/1
This hint should be set before a controller is opened. The number of haptic axes won't exceed the number
of real axes found on the device.
AVAILABILITY
This hint is available since SDL 3.2.5.
