# D3D12_ROOT_SIGNATURE_DESC1

> 描述根签名版本 1.1 的布局。

描述根签名版本 1.1 的布局。

## 语法

```cpp theme={null}
typedef struct D3D12_ROOT_SIGNATURE_DESC1
{
    UINT NumParameters;
    const D3D12_ROOT_PARAMETER1  pParameters;
    UINT NumStaticSamplers;
    const D3D12_STATIC_SAMPLER_DESC  pStaticSamplers;
    D3D12_ROOT_SIGNATURE_FLAGS Flags;
} D3D12_ROOT_SIGNATURE_DESC1
```

### 成员

*NumParameters*\
类型：UINT

根签名中的槽位数。此数字也是 <i>pParameters</i> 数组中的元素数量。

*pParameters*\
类型：const D3D12\_ROOT\_PARAMETER1 \*

一个 [D3D12\_ROOT\_PARAMETER1](/reference/graphics/d3d12/structs/d3d12_root_parameter1_public) 结构数组，用于根签名中的槽位。

*NumStaticSamplers*\
类型：UINT

指定静态采样器的数量。

*pStaticSamplers*\
类型：const D3D12\_STATIC\_SAMPLER\_DESC \*

指向一个或多个 [D3D12\_STATIC\_SAMPLER\_DESC](/reference/graphics/d3d12/structs/d3d12_static_sampler_desc_public) 结构的指针。

*Flags*\
类型：D3D12\_ROOT\_SIGNATURE\_FLAGS

指定 [D3D12\_ROOT\_SIGNATURE\_FLAGS](/reference/graphics/d3d12_xs/enums/d3d12_root_signature_flags_xs)，用于确定数据的易变性。

## 备注

将此结构与 [D3D12\_VERSIONED\_ROOT\_SIGNATURE\_DESC](/reference/graphics/d3d12/structs/d3d12_versioned_root_signature_desc_public) 结构一起使用。

## 要求

**头文件：** d3d12\_xs.h 或 d3d12\_x.h\
**库：** d3d12\_xs.lib 或 d3d12\_x.lib\
**支持的平台**：XBOX Series 主机和 XBOX One 系列
