# CheckFeatureSupport

> 获取有关当前图形驱动程序支持的功能的信息。(ID3D12Device.CheckFeatureSupport)

获取有关当前图形驱动程序支持的功能的信息。

## 语法

```cpp theme={null}
HRESULT CheckFeatureSupport(
    D3D12_FEATURE Feature,
    void  pFeatureSupportData,
    UINT FeatureSupportDataSize
)
```

### 参数

*Feature*\
类型：D3D12\_FEATURE

来自 [D3D12\_FEATURE](/reference/graphics/d3d12/enums/d3d12_feature_public) 枚举的常量，用于描述要查询支持情况的功能。

*pFeatureSupportData \[in, out]*\
类型：void \*

指向与 <i>Feature</i> 参数的值相对应的数据结构的指针。若要确定每个常量对应的数据结构，请参阅 [D3D12\_FEATURE](/reference/graphics/d3d12/enums/d3d12_feature_public)。

*FeatureSupportDataSize*\
类型：UINT

<i>pFeatureSupportData</i> 参数所指向的结构体大小。

### 返回值

类型：HRESULT

如果成功，则返回 **S\_OK**。如果向 <i>pFeatureSupportData</i> 参数传递了不受支持的数据类型，或者检测到 <i>FeatureSupportDataSize</i> 参数的大小不匹配，则返回 **E\_INVALIDARG**。

## 备注

作为使用示例，若要检查光线跟踪支持情况，请在 <i>pFeatureSupportData</i> 参数中指定 [D3D12\_FEATURE\_DATA\_D3D12\_OPTIONS5](/reference/graphics/d3d12/structs/d3d12_feature_data_d3d12_options5_public) 结构体。当函数成功完成时，访问现已填充的 **D3D12\_FEATURE\_DATA\_D3D12\_OPTIONS5** 结构体的 <i>RaytracingTier</i> 字段（该字段指定支持的光线跟踪层级）。

#### 示例

[D3D1211on12](https://learn.microsoft.com/en-us/windows/desktop/direct3d12/working-samples) 示例按以下方式使用 **ID3D12Device::CheckFeatureSupport**：

```cpp theme={null}
inline UINT8 D3D12GetFormatPlaneCount(
_In_ ID3D12Device* pDevice,
DXGI_FORMAT Format
)
{
D3D12_FEATURE_DATA_FORMAT_INFO formatInfo = {Format};
if (FAILED(pDevice->CheckFeatureSupport(D3D12_FEATURE_FORMAT_INFO, &formatInfo, sizeof(formatInfo))))
{
return 0;
}
return formatInfo.PlaneCount;
}

```

## 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
