Overview
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.
The usage pattern follows, and the curly braces are not necessary, but can be used for clarity:
var mutex sync.Mutex
...
mutex.Lock() {
// do something in a mutual exclusion mode
}
mutex.Unlock()
