Overview

Package atomic provides low-level atomic memory primitives useful for implementing synchronization algorithms. These functions require great care to be used correctly. Except for special, low-level applications, synchronization is better done with channels or the facilities of the sync package. Share memory by communicating; don't communicate by sharing memory.

When goroutines attempt to call any atomic function, they're automatically synchronized agains the variable that is being referenced.
