# XblSocialManagerUserGroupGetUsersTrackedByGroup

> XblSocialManagerUserGroupGetUsersTrackedByGroup

Gets a pointer to an XSAPI owned array of xuids tracked by the group.

## Syntax

```cpp theme={null}
HRESULT XblSocialManagerUserGroupGetUsersTrackedByGroup(  
         XblSocialManagerUserGroupHandle group,  
         const uint64_t** trackedUsers,  
         size_t* trackedUsersCount  
)  
```

### Parameters

*group*   \_In\_\
Type: [XblSocialManagerUserGroupHandle](https://docs.xbox.com/reference/live/xsapi-c/social_manager_c/handles/xblsocialmanagerusergrouphandle.md)

The group from which to get users.

*trackedUsers*   \_Outptr\_result\_maybenull\_\
Type: uint64\_t\*\*

Passes back a pointer to tracked xuids array. The memory for the returned pointer remains valid until the next time [XblSocialManagerDoWork](https://docs.xbox.com/reference/live/xsapi-c/social_manager_c/functions/xblsocialmanagerdowork.md) is called.

*trackedUsersCount*   \_Out\_\
Type: size\_t\*

Passes back the size of the tracked users array.

### Return value

Type: HRESULT

HRESULT return code for this API operation.

## Remarks

For list-based groups, the set of tracked users is static (i.e. the list of xuids provided when the group is created), but for filter-based groups, the set tracked users changes as the local user's relationships change. Call this API after calling either [XblSocialManagerCreateSocialUserGroupFromFilters](https://docs.xbox.com/reference/live/xsapi-c/social_manager_c/functions/xblsocialmanagercreatesocialusergroupfromfilters.md) or [XblSocialManagerCreateSocialUserGroupFromList](https://docs.xbox.com/reference/live/xsapi-c/social_manager_c/functions/xblsocialmanagercreatesocialusergroupfromlist.md) to create an XblSocialManagerUserGroup. Have the XblSocialManagerUserGroupHandle returned by the [XblSocialManagerEventType](https://docs.xbox.com/reference/live/xsapi-c/social_manager_c/enums/xblsocialmanagereventtype.md)::SocialUserGroupLoaded event in [XblSocialManagerDoWork](https://docs.xbox.com/reference/live/xsapi-c/social_manager_c/functions/xblsocialmanagerdowork.md).
