The structure that defines an extended virtual joystick description

The caller must zero the structure and then initialize the version with SDL_VIRTUAL_JOYSTICK_DESC_VERSION before passing it to SDL_JoystickAttachVirtualEx() All other elements of this structure are optional and can be left 0.

\sa SDL_JoystickAttachVirtualEx

Fields
