# PFLobbyGetOwnerMigrationPolicy

> PFLobbyGetOwnerMigrationPolicy 参考，用于通过 PlayFab Multiplayer C++ SDK 读取 PlayFab 大厅上配置的所有者迁移策略。

获取大厅的所有者迁移策略。

## 语法

```cpp theme={null}
HRESULT PFLobbyGetOwnerMigrationPolicy(  
    PFLobbyHandle lobby,  
    PFLobbyOwnerMigrationPolicy* ownerMigrationPolicy  
)  
```

### 参数

**`lobby`**   PFLobbyHandle

大厅的句柄。

**`ownerMigrationPolicy`**   [PFLobbyOwnerMigrationPolicy\*](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/enums/pflobbyownermigrationpolicy)\
*output*

输出的所有者迁移策略。

### 返回值

类型：HRESULT

如果调用成功，则为 `S_OK`；否则为错误代码。可通过 [PFMultiplayerGetErrorMessage()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmultiplayer/functions/pfmultiplayergeterrormessage) 检索错误代码的可读形式。

## 备注

所有者迁移策略在大厅的整个生命周期内均不能更改。<br /><br /> 如果此大厅对象是通过调用 [PFMultiplayerJoinLobby()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayerjoinlobby) 创建的，则此方法将返回错误，直到 [PFMultiplayerStartProcessingLobbyStateChanges()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayerstartprocessinglobbystatechanges) 提供一个 [PFLobbyUpdatedStateChange](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/structs/pflobbyupdatedstatechange)，其中 [PFLobbyUpdatedStateChange::ownerMigrationPolicy](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/structs/pflobbyupdatedstatechange) 设置为 true。如果加入大厅成功，则可以保证在 PFMultiplayerStartProcessingLobbyStateChanges() 提供 [PFLobbyJoinLobbyCompletedStateChange](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/structs/pflobbyjoinlobbycompletedstatechange) 时，此字段已被填充。
