From 1981059eaccd58a641074a7c78c0dcec52eabfb2 Mon Sep 17 00:00:00 2001 From: Sven Eden Date: Mon, 17 Jul 2017 15:03:10 +0200 Subject: Prep v233: Add missing files from upstream and rename formats-util.[hc] Some functionality has been exported to the following files: - src/basic/env-util.[hc] - src/basic/exec-util.[hc] - src/shared/nsflags.[hc] The content of these files is now needed in elogind, and the files have been added as-is. Cleanup is done later. Further the header src/basic/formats-util.h has been renamed to src/basic/format-util.h --- src/shared/nsflags.h | 49 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 src/shared/nsflags.h (limited to 'src/shared/nsflags.h') diff --git a/src/shared/nsflags.h b/src/shared/nsflags.h new file mode 100644 index 000000000..152ab8b93 --- /dev/null +++ b/src/shared/nsflags.h @@ -0,0 +1,49 @@ +#pragma once + +/*** + This file is part of systemd. + + Copyright 2016 Lennart Poettering + + systemd is free software; you can redistribute it and/or modify it + under the terms of the GNU Lesser General Public License as published by + the Free Software Foundation; either version 2.1 of the License, or + (at your option) any later version. + + systemd is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
