From 456201fa222ab208aba45fa2d700a56f04876886 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Sat, 14 Mar 2009 15:26:28 +0100 Subject: pcm_resample: renamed implementation functions Added diversion functions to pcm_resample.c. These check which resampler is enabled at compile time (libsamplerate or fallback). This prepares the following patch. --- src/pcm_resample_internal.h | 79 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 79 insertions(+) create mode 100644 src/pcm_resample_internal.h (limited to 'src/pcm_resample_internal.h') diff --git a/src/pcm_resample_internal.h b/src/pcm_resample_internal.h new file mode 100644 index 00000000..af62b766 --- /dev/null +++ b/src/pcm_resample_internal.h @@ -0,0 +1,79 @@ +/* + * 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.
