Retrieves the state of the specified joystick remapped as a gamepad.
This function retrieves the state of the specified joystick remapped to an Xbox-like gamepad.
If the specified joystick is not present or does not have a gamepad mapping this function will return GLFW_FALSE but will not generate an error. Call @ref glfwJoystickPresent to check whether it is present regardless of whether it has a mapping.
The Guide button may not be available for input as it is often hooked by the system or the Steam client.
Not all devices have all the buttons or axes provided by @ref GLFWgamepadstate. Unavailable buttons and axes will always report GLFW_RELEASE and 0.0 respectively.
