From 63710ff5a6fb51715aac83ca9374ef47f97d6120 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Tue, 21 Apr 2009 22:46:41 +0200 Subject: test: added program "read_mixer" This little program is used to test mixer plugins in an isolated environment. This is ALSA-only currently, because we don't have a real "plugin list" yet, and I'm too lazy to implement a switch. --- test/read_mixer.c | 68 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 68 insertions(+) create mode 100644 test/read_mixer.c (limited to 'test/read_mixer.c') diff --git a/test/read_mixer.c b/test/read_mixer.c new file mode 100644 index 000000000..be6864ba1 --- /dev/null +++ b/test/read_mixer.c @@ -0,0 +1,68 @@ +/* + * Copyright (C) 2003-2009 The Music Player Daemon Project + * http://www.musicpd.org + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program 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.
