I want to extract shader program type informantion from shader byte code. I tried D3D11Reflect first, and I found the _D3D11_SHADER_DESC structure. But I couldn't identify which field stores program type information...

If you look in the d3d11shader.h header, you'll see it's encoded into the Version field in the 16-bit upper word:

typedef enum D3D11_SHADER_VERSION_TYPE

{

    D3D11_SHVER_PIXEL_SHADER    = 0,

    D3D11_SHVER_VERTEX_SHADER   = 1,

    D3D11_SHVER_GEOMETRY_SHADER = 2,



    // D3D11 Shaders

    D3D11_SHVER_HULL_SHADER     = 3,

    D3D11_SHVER_DOMAIN_SHADER   = 4,

    D3D11_SHVER_COMPUTE_SHADER  = 5,



    D3D11_SHVER_RESERVED0       = 0xFFF0,

} D3D11_SHADER_VERSION_TYPE;



#define D3D11_SHVER_GET_TYPE(_Version) 

(((_Version) >> 16) & 0xffff)

#define D3D11_SHVER_GET_MAJOR(_Version) 

(((_Version) >> 4) & 0xf)

#define D3D11_SHVER_GET_MINOR(_Version) 

(((_Version) >> 0) & 0xf)



typedef struct _D3D11_SHADER_DESC

{

    UINT    Version;  // Shader version

    ...

}  D3D11_SIGNATURE_PARAMETER_DESC;
