         XblMultiplayerManagerMember* hostMember  
)  
```

### 参数

*hostMember*   \_Out\_\
类型：[XblMultiplayerManagerMember\*](/reference/live/xsapi-c/multiplayer_manager_c/structs/xblmultiplayermanagermember)

### 返回值

类型：HRESULT

此 API 操作的 HRESULT 返回代码。如果主机成员不存在，则返回 `__HRESULT_FROM_WIN32(ERROR_NO_SUCH_USER)`。

## 备注

此函数检索代表游戏会话主机的成员的成员信息。如果游戏会话不存在，或者游戏会话没有主机成员，则该函数返回 `__HRESULT_FROM_WIN32(ERROR_NO_SUCH_USER)`。主机成员被定义为主机设备上索引最低的用户。<br />此函数返回的信息仅在再次调用 [XblMultiplayerManagerDoWork](/reference/live/xsapi-c/multiplayer_manager_c/functions/xblmultiplayermanagerdowork) 之前有效。
