Symbian (Backup sis on installing)安装时备份SIS的实现

核心提示：if(err==KErrNone){err = fs.SetModified(filename, entry.iModified);if(err!=KErrNone) // KErrInUse, or KErrPermissionDenied if the file is in "esource\"

if(err==KErrNone)

{

err = fs.SetModified(filename, entry.iModified);

if(err!=KErrNone) // KErrInUse, or KErrPermissionDenied if the file is in "esource\"

{

found = ETrue;

}

}

}

}

//找到后copy一份文件即可

if(found)

{

err = BaflUtils::CopyFile(fs, filename, KSisBackup);

User::LeaveIfError(err);

}
