# D3D12_META_COMMAND_DESC

> 描述元命令。

描述元命令。

## 语法

```cpp theme={null}
typedef struct D3D12_META_COMMAND_DESC
{
    GUID Id;
    LPCWSTR Name;
    D3D12_GRAPHICS_STATES InitializationDirtyState;
    D3D12_GRAPHICS_STATES ExecutionDirtyState;
} D3D12_META_COMMAND_DESC
```

### 成员

*Id*\
类型：GUID

唯一标识元命令的 [GUID](https://learn.microsoft.com/en-us/windows/win32/api/guiddef/ns-guiddef-guid)。

*Name*\
类型：LPCWSTR

元命令名称。

*InitializationDirtyState*\
类型：D3D12\_GRAPHICS\_STATES

声明由初始化元命令的调用所修改的命令列表状态。如果设置了所有状态位，则相当于调用 [ID3D12GraphicsCommandList::ClearState](/reference/graphics/d3d12/interfaces/id3d12graphicscommandlist/methods/id3d12graphicscommandlist_clearstate_public)。

*ExecutionDirtyState*\
类型：D3D12\_GRAPHICS\_STATES

声明由执行元命令的调用所修改的命令列表状态。如果设置了所有状态位，则相当于调用 [ID3D12GraphicsCommandList::ClearState](/reference/graphics/d3d12/interfaces/id3d12graphicscommandlist/methods/id3d12graphicscommandlist_clearstate_public)。

## 要求

**头文件：** d3d12\_xs.h 或 d3d12\_x.h\
**库：** d3d12\_xs.lib 或 d3d12\_x.lib\
