# PartyXblChatUser::SetCustomContext

> Configures an optional, custom pointer-sized context value with this local chat user object.

Configures an optional, custom pointer-sized context value with this local chat user object.

## Syntax

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

### Parameters

**`customContext`**   void\*\
*optional*

An arbitrary, pointer-sized value to store with the chat user object.

### Return value

PartyError

`c_partyErrorSuccess` if configuring the custom context succeeded or an error code otherwise. The human-readable form of the error code can be retrieved via [PartyXblManager::GetErrorMessage()](/services/playfab/multiplayer/networking/xblreference/classes/PartyXblManager/methods/partyxblmanager_geterrormessage).

## Remarks

The custom context is typically used as a "shortcut" that simplifies accessing local, title-specific memory associated with the chat user without requiring a mapping lookup. The value is retrieved using the [GetCustomContext()](/services/playfab/multiplayer/networking/xblreference/classes/PartyXblChatUser/methods/partyxblchatuser_getcustomcontext) method. <br /><br /> Any configured value is treated as opaque by the library, and is only valid on the local device; it is not transmitted over the network.

## Requirements

**Header:** PartyXboxLive.h
