# PartyXblChatUser::SetCustomContext

> 为此本地聊天用户对象配置一个可选的自定义指针大小上下文值。

为此本地聊天用户对象配置一个可选的自定义指针大小上下文值。

## 语法

```cpp theme={null}
PartyError SetCustomContext(  
    void* customContext  
)  
```

### 参数

**`customContext`**   void\*\
*可选*

要与聊天用户对象一起存储的任意指针大小值。

### 返回值

PartyError

如果配置自定义上下文成功，则为 `c_partyErrorSuccess`；否则为错误代码。可通过 [PartyXblManager::GetErrorMessage()](/services/playfab/multiplayer/networking/xblreference/classes/PartyXblManager/methods/partyxblmanager_geterrormessage) 检索错误代码的可读形式。

## 备注

自定义上下文通常用作"快捷方式"，简化对与聊天用户关联的本地、特定于游戏的内存的访问，而无需进行映射查找。该值使用 [GetCustomContext()](/services/playfab/multiplayer/networking/xblreference/classes/PartyXblChatUser/methods/partyxblchatuser_getcustomcontext) 方法检索。<br /><br /> 任何配置的值都被库视为不透明的，且仅在本地设备上有效；它不会通过网络传输。

## 要求

**头文件：** PartyXboxLive.h
