SDL_TryWaitSemaphore - See if a semaphore has a positive value and decrement it if it does.
Defined in SDL3/SDL_mutex.h

bool SDL_TryWaitSemaphore(SDL_Semaphore *sem);
This function checks to see if the semaphore pointed to by sem has a positive value and atomically decrements the semaphore value if it does. If the semaphore doesn't have a positive value, the function immediately returns false.
