From 38be0d13830efd2d98281c645c3a60afe05ffece Mon Sep 17 00:00:00 2001 From: Qt by Nokia Date: Wed, 27 Apr 2011 12:05:43 +0200 Subject: Initial import from the monolithic Qt. This is the beginning of revision history for this module. If you want to look at revision history older than this, please refer to the Qt Git wiki for how to use Git history grafting. At the time of writing, this wiki is located here: http://qt.gitorious.org/qt/pages/GitIntroductionWithQt If you have already performed the grafting and you don't see any history beyond this commit, try running "git log" with the "--follow" argument. Branched from the monolithic repo, Qt master branch, at commit 896db169ea224deb96c59ce8af800d019de63f12 --- src/3rdparty/freetype/src/tools/apinames.c | 443 +++++++++++++++++++++++++++++ 1 file changed, 443 insertions(+) create mode 100644 src/3rdparty/freetype/src/tools/apinames.c (limited to 'src/3rdparty/freetype/src/tools/apinames.c') diff --git a/src/3rdparty/freetype/src/tools/apinames.c b/src/3rdparty/freetype/src/tools/apinames.c new file mode 100644 index 0000000000..19aec500bf --- /dev/null +++ b/src/3rdparty/freetype/src/tools/apinames.c @@ -0,0 +1,443 @@ +/* + * This little program is used to parse the FreeType headers and + * find the declaration of all public APIs.
