From e205b25d65ccb380fa158711e24d55b6de5d9bc1 Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Thu, 16 Feb 2006 19:19:58 +0000 Subject: Reorganised the source tree. We now have src/ with a couple of subdirs: * daemon/ - Contains the files specific to the polypaudio daemon. * modules/ - All loadable modules. * polyp/ - Files that are part of the public, application interface or are only used in libpolyp. * polypcore/ - All other shared files. * tests/ - Test programs. * utils/ - Utility programs. git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@487 fefdeb5f-60dc-0310-8127-8f9354f1896f --- polyp/module-pipe-sink.c | 236 ----------------------------------------------- 1 file changed, 236 deletions(-) delete mode 100644 polyp/module-pipe-sink.c (limited to 'polyp/module-pipe-sink.c') diff --git a/polyp/module-pipe-sink.c b/polyp/module-pipe-sink.c deleted file mode 100644 index 20e220ce..00000000 --- a/polyp/module-pipe-sink.c +++ /dev/null @@ -1,236 +0,0 @@ -/* $Id$ */ - -/*** - This file is part of polypaudio. - - polypaudio 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 of the License, - or (at your option) any later version. - - polypaudio 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.
