how to get the specific name of the workset which is currently selected by the user in sap portal 7.0

Dear Expert,

I have one requirement like to read the selected workset name in portal by the current user.I have read two documents regarding how to retrieve the PCD contents (iViews, Pages, Worksets and Roles) and its properties like Created by, Changed by, Last changed by and others using PCD API.

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/6112ecb7-0a01-0010-ef90-941c70c9e401?overridelayout=true

But I am not able to understand how to get the specific name of the workset which is currently selected by the user.Can you please help me.

I am using portal 7.0.

Thanks & Regards,
