one more legal/protocol question

[Misha Koshelev]

Dear All:

I may be mistaken, but it appears that the constants used for D3DX Mesh
Options:
http://msdn.microsoft.com/en-us/library/bb205746%28v=VS.85%29.aspx

are not yet present in Wine.

For example, in the main Wine source directory the command:

find . -name *.h -exec grep D3DXMESH_32BIT {} ;

does not return any results.

I would like to add these constants.

My question:
Can I simply 
1) look at the relevant DirectX 9 Microsoft .h files and add the
constants (rewriting of course not copy paste) from there?
or
2) do I have to do something more complicated?

Thank you
Misha

This should come from the PSDK (that is the Microsoft SDK that is 
publically available.)  This cannot come from non-public sources and/or 
source code....

This may be the truth.  Others may chime in and advise further.

I believe you can.

No, I don't think so.

There are legal precedents if you like, e.g. the Microsoft/Lotus
trial, but IANAL, so I don't think citing them would be much help.
Reading publicly available header files and recreating them is what
we've done, so you should be safe doing so as well.

Thank you. Onwards then with this approach.

Interestingly MSDN has some quite interesting typos:
http://msdn.microsoft.com/en-us/library/bb205370%28v=VS.85%29.aspx

specifically, LPD3DXMESH is indeed defined in the header file as an
ID3DXMesh * and _not_ a pointer to the enumeration.

Oh well, go figure.

Thanks guys!

p.s. You guys work too hard! I hope Codeweavers gives you a nice
break... or overtime ;)
