Subject: [PATCH v4 03/11] dir.c: provide clear_directory() for reclaiming dir_struct memory
Date: Sun, 6 Jan 2013 16:58:05 +0000 [thread overview]
Message-ID: <1357491493-11619-4-git-send-email-git@adamspiers.org> (raw)
In-Reply-To: <1357491493-11619-1-git-send-email-git@adamspiers.org>
By the end of a directory traversal, a dir_struct instance will
typically contains pointers to various data structures on the heap.
clear_directory() provides a convenient way to reclaim that memory.
