# WdCreateCancellationHandle

创建一个取消句柄，可用于取消由 [WdRemoteCopy](https://docs.xbox.com/zh-CN/reference/remoting/functions/wdremotecopy.md) 启动的复制操作。

## 语法

```cpp theme={null}
HRESULT WdCreateCancellationHandle(  
         _Out_ WdCancellationHandle* cancellationHandle  
);  
```

### 参数

`_Out_ cancellationHandle`\
类型：**[WdCancellationHandle](https://docs.xbox.com/zh-CN/reference/remoting/structs/wdcancellationhandle.md)\***

接收新创建的取消句柄。调用方负责在不再需要时通过调用 [WdCloseCancellationHandle](https://docs.xbox.com/zh-CN/reference/remoting/functions/wdclosecancellationhandle.md) 来释放该句柄。

### 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

在启动复制操作之前调用 `WdCreateCancellationHandle` 以获取用于实现取消功能的句柄。将该句柄通过 `cancellationHandle` 参数传递给 [WdRemoteCopy](https://docs.xbox.com/zh-CN/reference/remoting/functions/wdremotecopy.md)，然后从单独的线程将其传递给 [WdCancelRemoteCopy](https://docs.xbox.com/zh-CN/reference/remoting/functions/wdcancelremotecopy.md) 以取消操作。

在 `WdRemoteCopy` 返回后，通过调用 [WdCloseCancellationHandle](https://docs.xbox.com/zh-CN/reference/remoting/functions/wdclosecancellationhandle.md) 关闭句柄。该句柄可在多次 `WdRemoteCopy` 调用之间重复使用，但每个句柄最终都必须被关闭。
