Symbian如何临听文件目录的变化(NotifyChange)

通常我们在设计程序的时候,可能需要一个UI还需要一个后台的应用程序.
通常根据情况UI需要修改某些配置文件来控制后台应用程序.
这样后台需要有办法监听文件的变化.
看我们如何实现这个监听过程

void CMyCNotify::StartMonitoring()
{
   if(!IsActive())    
        {
    //ENotifyEntry 监听目录的变化
    //ENotifyFile监听文件的变化
    //ENotifyDir监听路径的变化
        iFs.NotifyChange(ENotifyEntry, iStatus, _L("c:\\data\\"));//临听对应的目录
    SetActive();
        }
}
