Yes, you’re right, you must pass flags to it.

Hm It didn’t take zero args. Passed in a null for see but didn’t work.

Actually it returns a Sint16 … but the implicit cast to float (%f) should
work isn’t it ?Anyway, better using %d for that purpose, to make sure …Just a
remark, if you say SDL_Init(SDL_INIT_JOYSTICK) then, if I’m
correct,SDL_InitSubSystem(SDL_INIT_JOYSTICK) is implicitely called, so you
don’t need it.However, you’d do:SDL_Init(); /* no args */SDL_InitSubSystem
(SDL_INIT_JOYSTICK);Correct me if I’m wrongJulien
