1-2) Atomically replaces the value pointed to by obj with the value of desr as if by obj->store(desr)

3-4) Atomically replaces the value pointed to by obj with the value of desr as if by obj->store(desr, order)

obj	-	pointer to the atomic object to modify
desr	-	the value to store in the atomic object
order	-	the memory synchronization ordering for this operation: only std::memory_order_relaxed, std::memory_order_release and std::memory_order_seq_cst are permitted.

std::atomic_store(std::shared_ptr) std::atomic_store_explicit(std::shared_ptr)	specializes atomic operations for std::shared_ptr (function template)
