query regarding _DYNAMIC structure

[Channa <channa.kad%gmail.com@localhost>]

Hi,
I am trying to use dladdr() API to print the symbol name & address.
But the problem notice is the _DYNAMIC structure does not contain the
DT_HASH tag,
where the symbol has table length 'nchains' is getting filled.

Can anyone suggest me how the _DYNAMIC structure is prepared?

Thanks in Advance,
