Raman,
Good question!! I had posted a similar problem sometime back.
http://www.ethereal.com/lists/ethereal-dev/200605/msg00149.html
After reading your question I just realized that the pseudo_header has to be re-populated all over again in the seek_read function. I was not doing it. Thanks for your question, I might have found just the problem I have been struggling with for last 2 weeks.
thanks,
Ravi.

hi all,
I m writing decoder for new capture format.
(dectrace).
I have made a pseudo_header which will carry info
of frame_no, sender,receiver etc.
in wiretap : in read function the i m loading
pseudo_header with appropiate data & i m able to use this in dissector. (for
column information etc)
the problem :
when i m loading pseudo_header in seek_read (it is
showing correct info) e.g.
in wtap->pseudo_header.dec_hdr->step
but the same information in dissector is replaced
by 0
e.g. value of
pinfo->pseudo_header.dec_hdr->step is 0.
i m unable to understand why the same info if
loaded through read is raching correct at dissector when the same is loaded from
seek_read is replaced by 0 somewhere between exit of seek & entry to
dissector.
regards
Raman
