From d9b3196d6c8f4fa0e7d0a4771040762edaebb1ee Mon Sep 17 00:00:00 2001 From: Tavian Barnes Date: Thu, 23 May 2019 17:11:23 -0400 Subject: fsade: Refactor the POSIX.1e abstractions Since we're going to want to abstract more things that aren't part of POSIX.1e (like xattrs) in a similar way, let's give this a more generic name. And while we're at it, give it some more precise error reporting, and add some tests. --- fsade.h | 58 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 fsade.h (limited to 'fsade.h') diff --git a/fsade.h b/fsade.h new file mode 100644 index 0000000..d4e97c0 --- /dev/null +++ b/fsade.h @@ -0,0 +1,58 @@ +/**************************************************************************** + * bfs * + * Copyright (C) 2019 Tavian Barnes * + * * + * Permission to use, copy, modify, and/or distribute this software for any * + * purpose with or without fee is hereby granted. * + * * + * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * + * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * + * MERCHANTABILITY AND FITNESS.
