    PFLobbyHandle lobby,  
    bool* restrictInvitesToLobbyOwner

### 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

如果为 true，则只有大厅所有者可以发送邀请。如果为 false，则任何成员都可以发送邀请。此项仅可对客户端拥有的大厅设置为 true。<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::restrictInvitesToLobbyOwnerUpdated](/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。  <br /><br /> 如果此大厅对象是通过调用 [PFMultiplayerClaimServerLobby()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayerclaimserverlobby) 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::restrictInvitesToLobbyOwnerUpdated](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/structs/pflobbyupdatedstatechange) 设置为 true。如果领取大厅成功，则可以保证在 PFMultiplayerStartProcessingLobbyStateChanges() 提供 [PFLobbyClaimServerLobbyCompletedStateChange](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/structs/pflobbyclaimserverlobbycompletedstatechange) 时，此字段已被填充。
