Thanks for your reply,
I am reading some N number of packets. One line of header followed by the
hex dump. I could see the hex dump in the third window and dissection is
done
whenever packet is selected from the packet list pane.
1. I want to know Where the memory will be allocated for all the (hex
dump)bytes read by the ethereal of several packets so that whenever i call
dissection a tvbuff is created and we could get the hexbytes from that
tvbuff?.
2. whether memory will be allocated for all the raw bytes at the time of
reading the packets itself ? If so in which part of the code the alloocation
of memory is done?
regards
harsha
