flock

flock implements a thread-safe file lock.

It also includes a non-blocking TryLock() function to allow locking without blocking execution.

Installation

go get -u github.com/gofrs/flock

Usage

import "github.com/gofrs/flock"

fileLock := flock.New("/var/lock/go-lock.lock")

locked, err := fileLock.TryLock()

if err != nil {
	// handle locking error
}

if locked {
	// do work
	fileLock.Unlock()
}

For more detailed usage information take a look at the package API docs on GoDoc.
