Ken Thomases : dinput: Overhaul how the array of Mac device elements is built and sorted.
Module: wine Branch: master Commit: ab872f2f3629dab54e0a417462399ce5e554f7a7 URL: http://source.winehq.org/git/wine.git/?a=commit;h=ab872f2f3629dab54e0a417462... Author: Ken Thomases <ken(a)codeweavers.com> Date: Sun Apr 13 18:34:16 2014 -0500 dinput: Overhaul how the array of Mac device elements is built and sorted. Use three separate arrays instead of one array with three sections that are separately tracked. Use the Core Foundation sort function rather than implementing a clumsy sort of our own. --- dlls/dinput/joystick_osx.c | 88 ++++++++++++++++++++------------------------ 1 file changed, 39 insertions(+), 49 deletions(-) diff --git a/dlls/dinput/joystick_osx.c b/dlls/dinput/joystick_osx.c index 1d7e970..a98c1ea 100644 --- a/dlls/dinput/joystick_osx.c +++ b/dlls/dinput/joystick_osx.c @@ -108,7 +108,7 @@ struct JoystickImpl /* osx private */ int id;
