Wait until a semaphore has a positive value and then decrements it.
int SDL_WaitSemaphoreTimeout(SDL_Semaphore *sem, Sint32 timeoutMS);
|sem||the semaphore to wait on|
|timeoutMS||the length of the timeout, in milliseconds|
Returns 0 if the wait succeeds,
SDL_MUTEX_TIMEDOUT if the wait does not succeed in the allotted time, or a negative error code on failure; call SDL_GetError() for more information.
This function suspends the calling thread until either the semaphore pointed to by
sem has a positive value, the call is interrupted by a signal or error, or the specified time has elapsed. If the call is successful it will atomically decrement the semaphore value.
This function is available since SDL 3.0.0.
