ID3D11ClassLinkage::CreateClassInstance Method

Initializes a class-instance object that represents an HLSL class instance.

Syntax

public:
HRESULT CreateClassInstance(
         LPCSTR pClassTypeName,
         UINT ConstantBufferOffset,
         UINT ConstantVectorOffset,
         UINT TextureOffset,
         UINT SamplerOffset,
         ID3D11ClassInstance **ppInstance
)

Parameters

pClassTypeName
Type: LPCSTR

[in] The type name of a class to initialize.

ConstantBufferOffset
Type: UINT

[in] Identifies the constant buffer that contains the class data.

ConstantVectorOffset
Type: UINT

[in] The four-component vector offset from the start of the constant buffer where the class data will begin. Consequently, this is not a byte offset.

TextureOffset
Type: UINT

[in] The texture slot for the first texture; there may be multiple textures following the offset.

SamplerOffset
Type: UINT

[in] The sampler slot for the first sampler; there may be multiple samplers following the offset.

ppInstance
Type: ID3D11ClassInstance **

[out] The address of a pointer to an ID3D11ClassInstance interface to initialize.

Return value

Type: HRESULT

Returns S_OK if successful; otherwise, returns one of the following Direct3D 11 return codes.

Remarks

Instances can be created (or gotten) before or after a shader is created. Use the same shader linkage object to acquire a class instance and create the shader the instance is going to be used in.
