From 3b653205cf7bd3851befd0a9f6a3ded6e267c173 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Thu, 10 Jul 2014 21:15:26 +0200 Subject: shared: split out in_addr related calls from socket-util.[ch] into its private in-addr-util.[ch] These are enough calls for a new file, and they are sufficiently different from the sockaddr-related calls, hence let's split this out. --- src/shared/in-addr-util.h | 44 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 src/shared/in-addr-util.h (limited to 'src/shared/in-addr-util.h') diff --git a/src/shared/in-addr-util.h b/src/shared/in-addr-util.h new file mode 100644 index 0000000000..ae3aa9021d --- /dev/null +++ b/src/shared/in-addr-util.h @@ -0,0 +1,44 @@ +/*-*- Mode: C; c-basic-offset: 8; indent-tabs-mode: nil -*-*/ + +#pragma once + +/*** + This file is part of systemd. + + Copyright 2014 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.
