From 5683f076331d2831eb4720b65bb53e8d01ca33ee Mon Sep 17 00:00:00 2001 From: Einar Johan Trøan Sømåen Date: Sat, 21 Jul 2012 18:19:07 +0200 Subject: WINTERMUTE: Rename CamelCased filenames to prefixed_under_score-filenames This is mostly a lead-up to namespacing the Ad/Base folders, and then possibly removing the prefixes from the files, it also has the added benefit of getting rid of the odd case-typos that makes for issues on platforms that don't ignore case. --- engines/wintermute/system/sys_class.cpp | 211 ++++++++++++++++++++++++++++++++ 1 file changed, 211 insertions(+) create mode 100644 engines/wintermute/system/sys_class.cpp (limited to 'engines/wintermute/system/sys_class.cpp') diff --git a/engines/wintermute/system/sys_class.cpp b/engines/wintermute/system/sys_class.cpp new file mode 100644 index 0000000000..be70f8b8bd --- /dev/null +++ b/engines/wintermute/system/sys_class.cpp @@ -0,0 +1,211 @@ +/* ScummVM - Graphic Adventure Engine + * + * ScummVM is the legal property of its developers, whose names + * are too numerous to list here.
