# WdDuplicateCancellationHandle

复制现有的 [WdCancellationHandle](/reference/remoting/structs/wdcancellationhandle)。

## 语法

```cpp theme={null}
HRESULT WdDuplicateCancellationHandle(  
         _In_ WdCancellationHandle cancellationHandle,  
         _Out_ WdCancellationHandle* duplicatedHandle  
);  
```

### 参数

`_In_ cancellationHandle`\
类型：**[WdCancellationHandle](/reference/remoting/structs/wdcancellationhandle)**

要复制的取消句柄。

`_Out_ duplicatedHandle`\
类型：**[WdCancellationHandle](/reference/remoting/structs/wdcancellationhandle)\***

接收复制得到的取消句柄。调用方负责通过调用 [WdCloseCancellationHandle](/reference/remoting/functions/wdclosecancellationhandle) 独立关闭该句柄。

### 返回值

类型：**HRESULT**

如果成功，则返回 `S_OK`；否则，返回错误代码。

## 备注

当多个组件需要引用同一取消句柄时，请使用 `WdDuplicateCancellationHandle`。原始句柄和复制的句柄都引用相同的取消状态——通过在任一句柄上调用 [WdCancelRemoteCopy](/reference/remoting/functions/wdcancelremotecopy) 发出取消信号，都会取消关联的 [WdRemoteCopy](/reference/remoting/functions/wdremotecopy) 操作。每个句柄都必须使用 [WdCloseCancellationHandle](/reference/remoting/functions/wdclosecancellationhandle) 独立关闭。

## 要求
