flock
implements a thread-safe sync.Locker interface for file locking. It also
includes a non-blocking TryLock() function to allow locking without blocking execution.
flock
is released under the BSD 3-Clause License. See the LICENSE
file for more details.
This package makes use of the context
package that was introduced in Go 1.7. As such, this
package has an implicit dependency on Go 1.7+.
go get -u github.com/gofrs/flock
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.
