sync.Mutex

sync.Mutex provides mutual exclusion: one goroutine can hold the lock at a time. Lock waits for ownership, TryLock attempts without waiting, and Unlock releases the lock.

Last updated

Syntax

type Mutex struct
func (m *Mutex) Lock()
func (m *Mutex) TryLock() bool
func (m *Mutex) Unlock()
