Doesn't the Section on Atomics <https://go.dev/ref/mem#atomic> statement say just that: The APIs in the sync/atomic <https://go.dev/pkg/sync/atomic/> package are collectively “atomic operations” that can be used to synchronize the execution of different goroutines. If the effect of an atomic operation *A* is observed by atomic operation *B*, then *A* is synchronized before *B*. All the atomic operations executed in a program behave as though executed in some sequentially consistent order. Is your confusion about the term "observed"? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
