         size_t usersCount  
)  
```

## Remarks

Call this API after calling either [XblSocialManagerCreateSocialUserGroupFromFilters](/reference/live/xsapi-c/social_manager_c/functions/xblsocialmanagercreatesocialusergroupfromfilters) or [XblSocialManagerCreateSocialUserGroupFromList](/reference/live/xsapi-c/social_manager_c/functions/xblsocialmanagercreatesocialusergroupfromlist) to create an XblSocialManagerUserGroup. Have the XblSocialManagerUserGroupHandle returned by the [XblSocialManagerEventType](/reference/live/xsapi-c/social_manager_c/enums/xblsocialmanagereventtype)::SocialUserGroupLoaded event in [XblSocialManagerDoWork](/reference/live/xsapi-c/social_manager_c/functions/xblsocialmanagerdowork).
