i read ur answer, see i m just using these values directly, like big/little endian or message_type.(depending on message type it will decode for that message.

 

in simple language - i have to get that pseudo header value in one variable in dissector while pseudo header is read through seek_read.

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
