From d02608170e599b1ffbc7c9a22062bae2579d6e36 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Sun, 25 Oct 2015 23:20:05 +0100 Subject: util: remove lookup_uid(), replace by uid_to_name() So far we had two pretty much identical calls in user-util.[ch]: lookup_uid() and uid_to_name(). Get rid of the former, in favour of the latter, and while we are at it, rewrite it, to use getpwuid_r() correctly, inside an allocation loop, as POSIX intended. --- src/test/test-user-util.c | 53 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 53 insertions(+) create mode 100644 src/test/test-user-util.c (limited to 'src/test/test-user-util.c') diff --git a/src/test/test-user-util.c b/src/test/test-user-util.c new file mode 100644 index 0000000000..dfd2031998 --- /dev/null +++ b/src/test/test-user-util.c @@ -0,0 +1,53 @@ +/*-*- Mode: C; c-basic-offset: 8; indent-tabs-mode: nil -*-*/ + +/*** + This file is part of systemd. + + Copyright 2015 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.
