# XAsyncSchedule

# XAsyncSchedule

为异步提供程序的回调函数计划工作。

## Syntax

```cpp theme={null}
HRESULT XAsyncSchedule(  
         XAsyncBlock* asyncBlock,  
         uint32_t delayInMs  
)  
```

### Parameters

*asyncBlock*   \_Inout\_\
类型：[XAsyncBlock\*](/reference/system/xasync/structs/xasyncblock)

指向为异步调用传递给 [XAsyncBegin](/reference/system/xasyncprovider/functions/xasyncbegin) 的 [XAsyncBlock](/reference/system/xasync/structs/xasyncblock) 的指针。

*delayInMs*   \_In\_\
类型：uint32\_t

系统在向异步队列计划异步调用之前应等待的时长（以毫秒为单位）。

### Return value

类型：[HRESULT](https://learn.microsoft.com/openspecs/windows_protocols/ms-erref/0642cb2f-2075-4469-918c-4441e69c548a)

成功时返回 `S_OK`；否则，返回错误代码。有关错误代码列表，请参阅[错误代码](/reference/errorcodes)。

## Remarks

此函数是可选的，可对异步提供程序的异步工作计划提供更多控制。如果异步工作可以通过系统管理的异步机制（例如[重叠 I/O](https://learn.microsoft.com/windows/win32/api/minwinbase/ns-minwinbase-overlapped?redirectedfrom=MSDN)）来完成，则无需调用此函数。

如果应在延迟后计划异步工作，请在 *delayInMs* 中指定 [XAsyncSchedule](/reference/system/xasyncprovider/functions/xasyncschedule) 在计划异步工作之前应等待的毫秒数。

有关使用 `XAsyncSchedule` 计划异步工作的异步提供程序示例，请参阅[异步编程模型](/build/core-features/common/async/async-programming-model#heading-7)中的"异步库"部分。
