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 --- src/polypcore/queue.h | 40 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 src/polypcore/queue.h (limited to 'src/polypcore/queue.h') diff --git a/src/polypcore/queue.h b/src/polypcore/queue.h new file mode 100644 index 00000000..3edcfb63 --- /dev/null +++ b/src/polypcore/queue.h @@ -0,0 +1,40 @@ +#ifndef fooqueuehfoo +#define fooqueuehfoo + +/* $Id$ */ + +/*** + 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 2.1 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.
