From eb15151705d47d23da844449126cc6b4879f110e Mon Sep 17 00:00:00 2001 From: wm4 Date: Tue, 17 Dec 2013 02:02:25 +0100 Subject: Move options/config related files from mpvcore/ to options/ Since m_option.h and options.h are extremely often included, a lot of files have to be changed. Moving path.c/h to options/ is a bit questionable, but since this is mainly about access to config files (which are also handled in options/), it's probably ok. --- options/m_config.c | 755 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 755 insertions(+) create mode 100644 options/m_config.c (limited to 'options/m_config.c') diff --git a/options/m_config.c b/options/m_config.c new file mode 100644 index 0000000000..5040482c84 --- /dev/null +++ b/options/m_config.c @@ -0,0 +1,755 @@ +/* + * This file is part of MPlayer. + * + * MPlayer 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. + * + * MPlayer 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.
