type FileLock interface {

func TryLockFile ¶
TryLockFile and the returned FileLock implements Cooperative File Locking using a ".lock"-suffixed file that is atomically created to acquire the lock.
Cooperative file locking, such as implemented here, is not enforced at any level. Instead, it relies on participating threads/processes following the same procedure before changing protected files.
