Serializes a root signature of any version that can be passed to ID3D12Device::CreateRootSignature.
HRESULT D3D12SerializeVersionedRootSignature( const D3D12_VERSIONED_ROOT_SIGNATURE_DESC *pRootSignature, ID3DBlob **ppBlob, ID3DBlob **ppErrorBlob );
Type: const D3D12_VERSIONED_ROOT_SIGNATURE_DESC*
Specifies a D3D12_VERSIONED_ROOT_SIGNATURE_DESC that contains a description of any version of a root signature.
A pointer to a memory block that receives a pointer to the ID3DBlob interface that you can use to access the serialized root signature.
A pointer to a memory block that receives a pointer to the ID3DBlob interface that you can use to access serializer error messages, or NULL if there are no errors.
Returns S_OK if successful; otherwise, returns one of the Direct3D 12 Return Codes.
If an application procedurally generates a D3D12_ROOT_SIGNATURE_DESC1 data structure, it must pass a pointer to this D3D12_ROOT_SIGNATURE_DESC1 in a call to D3D12SerializeVersionedRootSignature to make the serialized form. The application then passes the serialized form to which ppBlob points into ID3D12Device::CreateRootSignature.
If a shader has been authored with a root signature in it (when that capability is added), the compiled shader will contain a serialized root signature in it already.
The function signature PFN_D3D12_SERIALIZE_VERSIONED_ROOT_SIGNATURE is provided as a typedef, so that you can use dynamic linking techniques (GetProcAddress) instead of statically linking.
This function was released with the Windows 10 Anniversary Update (14393) and supersedes D3D12SerializeRootSignature.
