Hi Anton,
Entres implementation has been useful to me, thanks for pointing this out.
Based on this implementation I wrote sample program attached with this mail.
Though I am getting compilation error at line 151 which is pasted below: (I am
not able to figure out why compilation should complain here, passed type seems
correct to me)

Subject: Re: [Openhpi-devel] How to get rpt resourceId from Entity Path?
Preeti,
Could you try "lsent", "entres" and "entinstr" commands in hpi_shell?
