SDL_GetHint

The string value of a hint or null if the hint isn't set.

Threadsafety: It is safe to call this function from any thread, however the return value only remains valid until the hint is changed; if another thread might do so, the app should supply locks and/or make a copy of the string. Note that using a hint callback instead is always thread-safe, as SDL holds a lock on the thread subsystem during the callback.
