int SDL_CondWaitTimeout(SDL_cond *cond, SDL_mutex *mutex, Uint32 ms);
Wait on the condition variable cond for, at most, ms milliseconds. mut is unlocked so it must be locked when the function is called. Returns SDL_MUTEX_TIMEDOUT if the condition is not signalled in the allotted time, 0 if it was signalled or -1 on an error.
