Ok, I have a question about this but it may be obvious. How can you do anything patentable with virtual tables? They're pointers to arrays of function pointers. It's not like DirectX is even laced with virtual (or even multiple) inheritance or anything like that. That's the only reason their C interface system even works.
The most complicated thing I can imagine is how they determine the order of functions in the table, but from the C interface stuff it would appear that they're in declaration order... -Wade Wednesday, February 06, 2002, 12:20:23 PM, you wrote: B> What about the more important problem that Microsoft's patented virtual B> table system, which COM uses, isn't supported by GCC?
