Types

type Lock 

type Lock struct {
	// contains filtered or unexported fields
}

Lock is a held exclusive lock.

func Acquire 

func Acquire(path string) (*Lock, error)

Acquire creates path if needed (mode 0600) and blocks until it holds an exclusive lock on it. Callers lock a dedicated lock file, never the data file, so atomic rename of the data file cannot orphan the lock.

func (*Lock) Release 

func (l *Lock) Release()

Release drops the lock. It is safe to call more than once.
