void SDL_DestroySemaphore(SDL_sem *sem);

SDL_DestroySemaphore destroys the semaphore pointed to by sem that was created by SDL_CreateSemaphore. It is not safe to destroy a semaphore if there are threads currently blocked waiting on it.

if (my_sem != NULL) {
        SDL_DestroySemaphore(my_sem);
        my_sem = NULL;
}
