How to use Go Atomic concurrency
This article introduces the knowledge of "how to use Go Atomic concurrency". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
Locking costs are time-consuming and context switching is needed. For basic data types, atomic operations can be used to ensure thread safety, and atomic operations can be completed in user mode, so the performance is higher than that of mutexes.
Package mainimport ("fmt"sync"sync/atomic") var (wg sync.WaitGroup count int32 mu sync.Mutex) func incCount () {defer wg.Done () for I: = 0; I < 100000 This is the end of func main + {atomic.AddInt32 (& count,1)} func main () {wg.Add (2) go incCount () go incCount () wg.Wait () fmt.Println (count)} "how to use Go Atomic concurrency".
