You can create cow object on first fsinfo() call, ideally add some flags to control this behavior -- but you're right, this way is complicated to implement and possibly dangerous. I guess return some vector of attributes in one fsinfo() will be good enough. Karel -- Karel Zak <kzak@xxxxxxxxxx> http://karelzak.blogspot.com
