This interface is used to return arbitrary length data.
interface ID3D10Blob : public IUnknown
An ID3D10Blob is obtained by calling D3D10CreateBlob.
The ID3DBlob interface is type defined in the D3DCommon.h header file as a ID3D10Blob interface, which is fully defined in the D3DCommon.h header file. ID3DBlob is version neutral and can be used in code for any Direct3D version.
Blobs can be used as a data buffer, storing vertex, adjacency, and material information during mesh optimization and loading operations. Also, these objects are used to return object code and error messages in APIs that compile vertex, geometry and pixel shaders.
Header: Declared in d3d11_x.h (d3dcommon.h on other Windows platforms).
Library: Use d3d11_x.lib (d3d11.lib on other Windows platforms).
