Hi Jeff,
thank you for your answear. I was looking at the code, for what I
understood the matching is held by the function dfvm_apply. Are there any
connection beetween the structure dfilter_t and the original pcap file? I
can print the value matched pretty easily.

Hi to all,
maybe it's a silly question. Is it possibile to know what byte match in
display filter expression? For example if I have a pcap file with some
packet and I run tshark with -Y option I would like to know which bytes
match that expression, is it possibile?


Unfortunately no, not today.  There's been some discussion of highlighting
the field (if not the bytes) in the GUI (there's probably a bug requesting
that) but this is the first time I've heard of it for tshark.
