Use this function to try to lock a spin lock by setting it to a non-zero value.
SDL_bool SDL_AtomicTryLock(SDL_SpinLock* lock)
a pointer to a lock variable
Returns SDL_TRUE if the lock succeeded, SDL_FALSE if the lock is already held.

The atomic locks are efficient spinlocks using CPU instructions, but are vulnerable to starvation and can spin forever if a thread holding a lock has been terminated. For this reason you should minimize the code executed inside an atomic lock and never do expensive things like API or system calls while holding them.
The atomic locks are not safe to lock recursively.
