# XblMultiplayerManagerGameSessionCorrelationId

> XblMultiplayerManagerGameSessionCorrelationId

# XblMultiplayerManagerGameSessionCorrelationId

Retrieves the correlation handle for the game session.

## Syntax

```cpp theme={null}
const char* XblMultiplayerManagerGameSessionCorrelationId(  
)  
```

### Parameters

### Return value

Type: const char\*

The correlation handle for the game session, or null if a game session doesn't exist. The memory for the returned pointer remains valid until the next call to [XblMultiplayerManagerDoWork](/reference/live/xsapi-c/multiplayer_manager_c/functions/xblmultiplayermanagerdowork).

## Remarks

This function retrieves the correlation handle for the game session. The correlation handle serves as an alias for the game session, allowing a game to refer to a game session by using only the correlation handle. The correlation handle can be used to query trace logs for entries that relate to the game session. For more information, see [Multiplayer concepts overview](/services/xbox-services/multiplayer/concepts/live-multiplayer-concepts).

## Requirements

**Header:** multiplayer\_manager\_c.h
