# XblUserStatisticsTrackStatistics

Configures the set of stats that will be tracked real-time. This call will have no affect on stats that were already being tracked.

## Syntax

```cpp theme={null}
HRESULT XblUserStatisticsTrackStatistics(  
         XblContextHandle xblContextHandle,  
         const uint64_t* xboxUserIds,  
         size_t xboxUserIdsCount,  
         const char* serviceConfigurationId,  
         const char** statisticNames,  
         size_t statisticNamesCount  
)  
```

### Parameters

Type: size\_t

Length of xboxUserIds array.

*serviceConfigurationId*   \_In\_z\_\

*statisticNamesCount*   \_In\_\
Type: size\_t

### Return value

Type: HRESULT
