From ec38b4e482e96e62762452cab5714e55abdb48c3 Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Wed, 1 Oct 2014 12:28:39 +0200 Subject: get_locked_file_path(): new function Add a function to return the path of the file that is locked by a lock_file object. This reduces the knowledge that callers have to have about the lock_file layout.
