# PFMultiplayerFinishProcessingMatchmakingStateChanges

> 返回先前检索以进行处理的 PlayFab Multiplayer 匹配状态变更数组，将资源释放回库。

返回正在处理的匹配状态变更数组。

## 语法

```cpp theme={null}
HRESULT PFMultiplayerFinishProcessingMatchmakingStateChanges(  
    PFMultiplayerHandle handle,  
    uint32_t stateChangeCount,  
    const PFMatchmakingStateChange* const* stateChanges  
)  
```

### 参数

**`handle`**   PFMultiplayerHandle

PFMultiplayer API 实例的句柄。

**`stateChangeCount`**   uint32\_t

`stateChanges` 指定的列表中提供的、先前由 [PFMultiplayerStartProcessingMatchmakingStateChanges()](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmatchmaking/functions/pfmultiplayerstartprocessingmatchmakingstatechanges.md) 返回且现已被 title 处理的变更数量。

**`stateChanges`**   PFMatchmakingStateChange\* const\*\
*大小为 `stateChangeCount` 的输入数组*

先前由 [PFMultiplayerStartProcessingMatchmakingStateChanges()](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmatchmaking/functions/pfmultiplayerstartprocessingmatchmakingstatechanges.md) 返回且现已被 title 处理的变更数组。

### 返回值

类型：HRESULT

如果调用成功，则为 `S_OK`；否则为错误代码。可以通过 [PFMultiplayerGetErrorMessage()](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmultiplayer/functions/pfmultiplayergeterrormessage.md) 获取错误代码的人类可读形式。

## 备注

此方法通知匹配库：先前调用 [PFMultiplayerStartProcessingMatchmakingStateChanges()](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmatchmaking/functions/pfmultiplayerstartprocessingmatchmakingstatechanges.md) 报告的状态变更现已被 title 处理，因此可以回收其关联资源。可以以任意数量的状态变更调用 PFMultiplayerFinishProcessingMatchmakingStateChanges()。PFMultiplayerStartProcessingMatchmakingStateChanges() 返回的每个状态变更必须恰好一次返回给 PFMultiplayerFinishProcessingMatchmakingStateChanges()，但可以乱序返回，也可以与来自其他 PFMultiplayerStartProcessingMatchmakingStateChanges() 调用的状态变更交错返回。\
\
 与特定状态变更关联的任何资源都保证在该状态变更返回给 PFMultiplayerFinishProcessingMatchmakingStateChanges() 之前一直有效。\
\
 为获得最佳效果，应尽量减少在调用 PFMultiplayerFinishProcessingMatchmakingStateChanges() 之前处理状态变更所花费的时间。
