Does someone have an idea of the problem. I have a test program if you want
It's a known thing, C-compatible prototypes would be different for such
methods:
D2D1_SIZE_U * ID3D1HwndRenderTarget_GetPixelSize(void *this, D2D1_SIZE_U
*size).
but then I have a compilation error because in d2d1.h provided by
mingw-w64, GetPixelSize() has only 1 argument, not 2.
Naturally, because headers are not prepared for that.
If you wanted to use C++ with msvc compatible prototypes, there is
WIDL_EXPLICIT_AGGREGATE_RETURNS for that,
for C definitions it won't work, you'll have to use wine headers, or
more specifically a header widl produces from wine's d2d1.idl. Widl
detects such cases automatically, see is_aggregate_return() in widl sources.
I think what should be done is WIDL_EXPLICIT_AGGREGATE_RETURNS case for
C definitions patched in for mingw headers.
You could check hows it's done in Wine, where we don't use C++.
do you have a link, please ?
We don't have generated headers checked in in the tree, so you'll have
to get complete source tree, and build it, then see what generated
headers look like.
thank you
Vincent
