# XblMultiplayerManagerLobbySessionCorrelationId

> XblMultiplayerManagerLobbySessionCorrelationId

# XblMultiplayerManagerLobbySessionCorrelationId

擷取大廳工作階段的相互關聯控制代碼。

## 語法

```cpp theme={null}
HRESULT XblMultiplayerManagerLobbySessionCorrelationId(  
         XblGuid* correlationId  
)  
```

### 參數

*correlationId*   \_Out\_\
類型：[XblGuid\*](/zh-TW/reference/live/xsapi-c/types_c/structs/xblguid)

傳回大廳工作階段的相互關聯控制代碼；如果大廳工作階段不存在，則為 null。傳回之指標的記憶體在下次呼叫 [XblMultiplayerManagerDoWork](/zh-TW/reference/live/xsapi-c/multiplayer_manager_c/functions/xblmultiplayermanagerdowork) 之前都保持有效。

### 傳回值

類型：HRESULT

此 API 作業的 HRESULT 傳回碼。

## 備註

此函式會擷取 Multiplayer Manager (MPM) 中大廳工作階段的相互關聯控制代碼。相互關聯控制代碼可做為大廳工作階段的別名，讓遊戲只需使用相互關聯控制代碼即可參照大廳工作階段。相互關聯控制代碼可用來查詢追蹤記錄中與大廳工作階段相關的項目。如需詳細資訊，請參閱[多人遊戲概念概觀](/zh-TW/services/xbox-services/multiplayer/concepts/live-multiplayer-concepts)。

## 需求

**標頭：** multiplayer\_manager\_c.h
