// Purpose: Callback interface for receiving responses after a server list refresh
// or an individual server update.
//
// Since you get these callbacks after requesting full list refreshes you will
// usually implement this interface inside an object like CServerBrowser.  If that
// object is getting destructed you should use ISteamMatchMakingServers()->CancelQuery()
// to cancel any in-progress queries so you don't get a callback into the destructed
// object and crash.

// ISteamMatchmakingServers()->CancelServerQuery() passing in the handle to the query
// which is in progress.  Failure to cancel in progress queries when destructing
// a callback handler may result in a crash when a callback later occurs.
