# D3D12_CPU_PAGE_PROPERTY

> 指定堆的 CPU 页属性。

指定堆的 CPU 页属性。

## 语法

```cpp theme={null}
typedef enum D3D12_CPU_PAGE_PROPERTY
{
    D3D12_CPU_PAGE_PROPERTY_UNKNOWN = 0,
    D3D12_CPU_PAGE_PROPERTY_NOT_AVAILABLE = 1,
    D3D12_CPU_PAGE_PROPERTY_WRITE_COMBINE = 2,
    D3D12_CPU_PAGE_PROPERTY_WRITE_BACK = 3
} D3D12_CPU_PAGE_PROPERTY
```

## 常量

| 常量                                         | 说明                    |
| ------------------------------------------ | --------------------- |
| D3D12\_CPU\_PAGE\_PROPERTY\_UNKNOWN        | CPU 页属性未知。            |
| D3D12\_CPU\_PAGE\_PROPERTY\_NOT\_AVAILABLE | CPU 无法访问堆，因此没有可用的页属性。 |
| D3D12\_CPU\_PAGE\_PROPERTY\_WRITE\_COMBINE | CPU 页属性为写入合并。         |
| D3D12\_CPU\_PAGE\_PROPERTY\_WRITE\_BACK    | CPU 页属性为写回。           |
