[SOLVED] Is there a way to receive as a string, the errors from DX12?

Is there a way to receive as a string, the errors from DX12?

Example: Here's the debug log for CreateGraphicsPipelineState, it tells me what went wrong:

D3D12 ERROR: ID3D12Device::CreateGraphicsPipelineState: Root Signature doesn't match Vertex Shader: Shader CBV descriptor range (RegisterSpace=0, NumDescriptors=1, BaseShaderRegister=0) is not fully bound in root signature

However, a call to windows FormatMessage(MESSAGE_FROM_SYSTEM...) will return this for the exact same error:

The parameter is incorrect.

The first is obviously far more useful... We used to have dxerr.lib, and we have source for dxerr.cpp in DXUT. But this doesn't cover DX12. I can't see any way for a shader-tool to retrieve the error and present it to the user from the API.

Solution

This can be done with the ID3D12InfoQueue interface, as documented here:

https://learn.microsoft.com/en-us/windows/win32/api/d3d12sdklayers/nn-d3d12sdklayers-id3d12infoqueue

As far as I can tell it's currently not possible to set a callback, which means that you'll need to explicitly query for feedback.
