D3D12_ROOT_SIGNATURE_DESC structure (d3d12.h)

Describes the layout of a root signature version 1.0.

Syntax

typedef struct D3D12_ROOT_SIGNATURE_DESC {
  UINT                            NumParameters;
  const D3D12_ROOT_PARAMETER      *pParameters;
  UINT                            NumStaticSamplers;
  const D3D12_STATIC_SAMPLER_DESC *pStaticSamplers;
  D3D12_ROOT_SIGNATURE_FLAGS      Flags;
} D3D12_ROOT_SIGNATURE_DESC;

Members

NumParameters

The number of slots in the root signature. This number is also the number of elements in the pParameters array.

pParameters

An array of D3D12_ROOT_PARAMETER structures for the slots in the root signature.

NumStaticSamplers

Specifies the number of static samplers.

pStaticSamplers

Pointer to one or more D3D12_STATIC_SAMPLER_DESC structures.

Flags

A combination of D3D12_ROOT_SIGNATURE_FLAGS-typed values that are combined by using a bitwise OR operation. The resulting value specifies options for the root signature layout.

Remarks

This structure is used by the D3D12SerializeRootSignature function and is returned by the ID3D12RootSignatureDeserializer::GetRootSignatureDesc method.

There is one graphics root signature, and one compute root signature.
