Dear all,

Sorry to bother, but I could not find a clear answer and would like to check before doing any Wine work based on material with an unclear legal status.

I was looking into Wine's implementation of FDI and cabinet.dll. While looking at code examples using FDICreate and FDICopy, I stumbled upon an old GPL project called CapiTel.

The FDI.h contained in this project has many useful explanations for constants and functions that are poorly documented in the Microsoft Learn Win32 API reference, as well as in Wine's API reference.

However, the file says:

Copyright (C) Microsoft Corporation 1993-1997. All Rights Reserved.

I was wondering whether it is OK to use information learned from this header to document the Wine API. I was also wondering whether it would be acceptable to patch some of the functions based on what I learned from this header.

Thanks in advance for your help and guidance,
