Module: wine Branch: refs/heads/master Commit: 00ecbd05e8945e9f9e6fda078e13b0491e5dd73b URL: http://source.winehq.org/git/?p=wine.git;a=commit;h=00ecbd05e8945e9f9e6fda07... Author: Robert Shearman <rob(a)codeweavers.com> Date: Thu Feb 9 12:10:26 2006 +0100 oleaut: Revert incorrect patch changing the order of parameters passed into DispCallFunc. A test with native indeed shows that the parameter index increases from the leftmost parameter to the rightmost. --- dlls/oleaut32/typelib.c | 67 ++++++++++++++++++----------------------------- 1 files changed, 26 insertions(+), 41 deletions(-) diff --git a/dlls/oleaut32/typelib.c b/dlls/oleaut32/typelib.c index 8791736..8cface4 100644 --- a/dlls/oleaut32/typelib.c +++ b/dlls/oleaut32/typelib.c @@ -5112,9 +5112,6 @@ static HRESULT typedescvt_to_variantvt(I *|CC_MPWCDECL *|CC_MPWPASCAL * - * The rgpvarg array contains the parameters, but in the opposite order to - * what is usually assumed.
