Here, I am assuming that the "dwSize" elements in all these cases should be set to the size of the struct each is in, respectively. Please advise if this assumption is wrong.
It's not necessarily true. Sometimes there are multiple versions of the same structure. You can check ddraw.h and d3dtypes.h. If there is only one version your assumption should be true.
If there isn't, then your assumption may still be true. In that case there are some tests how the Setter methods deal with newer or older structures(in some cases we may need more tests)
Hi Stefan,
I checked that I wasn't assigning between entities whose types had different suffixes, such as assigning to a D3DVIEWPORT variable from one of type D3DVIEWPORT2, for example. (In fact, the only one I had to avoid was the assignment to a DDSURFACEDESC type variable from a DDSURFACEDESC2 one, in ddraw/ddraw_thunks.c.) And I presume that if the underlying struct tags are different between two similar types, then the compiler would warn of type incompatibility if such an assignment were attempted.
Thanks,
