FFI Wrapping Help

Hello all,

I am wondering how you would wrap this with the FFI library.

typedef struct SDL_GameControllerButtonBind 
{ 
    SDL_GameControllerBindType bindType; 
    union 
    { 
        int button; 
        int axis; 
        struct { 
            int hat; 
            int hat_mask; 
        } hat; 
    } value; 
 
} SDL_GameControllerButtonBind; 

I know with unions you can't exactly wrap them as you would with a normal struct.

My idea is

export constant SDL_GAMECONTROLLERBUTTONID = define_c_type({ 
  C_INT --button 
  C_INT --axis 
  C_POINTER --for struct 
  C_INT --hat 
  C_INT --hat_mask 
})
