         ID3D11ClassInstance **ppInstance
)

Parameters

pClassInstanceName

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

Return value

Type: HRESULT

Remarks

For more information about using the ID3D11ClassLinkage interface, see Dynamic Linking.

A class instance must have at least 1 data member in order to be available for the runtime to use with ID3D11ClassLinkage::GetClassInstance. Any instance with no members will be optimized out of a compiled shader blob as a zero-sized object. If you have a class with no data members, use ID3D11ClassLinkage::CreateClassInstance instead.
