Henri Verbeet : widl: Handle aggregate returns in a MSVC compatible way.
Module: wine Branch: master Commit: fabfa59aea5c5b3201142382038beb3e76cb7567 URL: http://source.winehq.org/git/wine.git/?a=commit;h=fabfa59aea5c5b320114238203... Author: Henri Verbeet <hverbeet(a)codeweavers.com> Date: Fri Sep 5 17:33:03 2014 +0200 widl: Handle aggregate returns in a MSVC compatible way. Aggregates are returned through an implicit parameter after the this/interface pointer. Note that this follows the C++ convention, affected methods are not callable from C with the Microsoft headers. --- dlls/d2d1/brush.c | 25 ++++++++++++++----------- dlls/d2d1/render_target.c | 25 ++++++++++++++----------- tools/widl/header.c | 43 +++++++++++++++++++++++++++++++++++++++---- 3 files changed, 67 insertions(+), 26 deletions(-) diff --git a/dlls/d2d1/brush.c b/dlls/d2d1/brush.c index d8b769b..ed92d60 100644 --- a/dlls/d2d1/brush.c +++ b/dlls/d2d1/brush.c @@ -227,13 +227,14 @@ static void STDMETHODCALLTYPE d2d_solid_color_brush_SetColor(ID2D1SolidColorBrus FIXME("iface %p, color %p stub!\n", iface, color);
