From dd7595a3475407a7fa96a97393bae8c5220e8762 Mon Sep 17 00:00:00 2001 From: David Walter Seikel Date: Wed, 4 Jan 2012 18:41:13 +1000 Subject: Add the base Enlightenment Foundation Libraries - eina, eet, evas, ecore, embryo, and edje. Note that embryo wont be used, but I'm not sure yet if you can build edje without it. --- libraries/edje/src/bin/epp/cpplib.h | 641 ++++++++++++++++++++++++++++++++++++ 1 file changed, 641 insertions(+) create mode 100644 libraries/edje/src/bin/epp/cpplib.h (limited to 'libraries/edje/src/bin/epp/cpplib.h') diff --git a/libraries/edje/src/bin/epp/cpplib.h b/libraries/edje/src/bin/epp/cpplib.h new file mode 100644 index 0000000..5653dd2 --- /dev/null +++ b/libraries/edje/src/bin/epp/cpplib.h @@ -0,0 +1,641 @@ +/* Definitions for CPP library. + Copyright (C) 1995 Free Software Foundation, Inc. + Written by Per Bothner, 1994-95. + +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, 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.
