Overview

The sync package provides synchronization primitives to use when synchronization between goroutines is necessary.

TO DISTRIBUTE

WaitGroup

WaitGroup

Mutex

A Mutex is a mutual exclusion lock. Only one goroutine can enter the critical section at a time. Not until the call to the Unlock() function issued can another goroutine enter the critical section.

Usage pattern (the curly braces are not necessary):

var mutex sync.Mutex

...

mutex.Lock() {
    // do something in a mutual exclusion mode
}

mutex.Unlock()
