IDirect3DShaderValidator9 is an undocumented Direct3D9 C/C++ interface that is exposed through the Direct3DShaderValidatorCreate9 function, which is a DLL-exported named function in d3d9.dll. A header file (with many missing definitions) was created for this interface, which is available here. Additionally, a working code sample illustrating how to use this undocumented interface is also included in this GitHub repo called "D3D9ShaderValidatorSample".
Potential users of this interface might include:
- People working with shader compiler tools for Shader Models 1, 2, and/or 3.
- Shader authors looking to debug issues with their shaders
- Documentarians seeking details of the enforced rules of Direct3D9 that may not be explicitly stated in the official MSDN documentation
- Conspiracy theorists who are not sure what that one weird function exported in a very commonly-used DLL is for
Just download the header file from here and #include it in your code: d3d9_shadervalidator.h
If you are interested in checking out the sample code, you can clone or download this repo, and then build and run the Solution file with a recent version of Visual Studio (I used VS2017 here, but it's likely that older versions will work too just fine).
