Implementing d3dx9_36.dll.D3DXCreateTexture

[Christoph Brill]

Hi list,

I'm trying to get a DirectX model viewer[1] to run. Using wine 1.1.4 it
is possible to lauch because d3dx9_36.dll exists but a method
(CreateTexture) of it is stubbed out. I started looking for details on
this and came up with this MSDN link[2]. Looking at the code I found
that this method is already implemented in the core d3d9 library in
dlls/d3d9/texture.c. From what I understand a forward to this function
should be enough to get this method to work since the parameters seem to
match (except the last parameter in the core d3d9 (HANDLE*
pSharedHandle) does not exist in the MSDN definition).

Can someone please comment if my thoughts are right here?

Thanks,
  Christoph

Hi,

For basic operation just forwarding to the d3d9 CreateTexture call should work fine but note the following:
"Internally, D3DXCreateTexture uses D3DXCheckTextureRequirements to adjust the calling parameters. Therefore, calls to D3DXCreateTexture will often succeed where calls to IDirect3DDevice9::CreateTexture would fail."

As a start I wouldn't add that behavior but add a comment that the function isn't complete and what is missing. I would also print a FIXME about it but only show it once in total (so use a static variable).
