Well, it's only a hack for the moment :)

I did this lib because I wanted to use qpe developping tools (ui
and makefile generators) which prevented me from linking to, say,
packet-*.o. So I built a library to gather them :
ar r libzethereal.a packet-*.o afn.o asn1.o column.o conditions.o
capture_stop_conditions.o follow.o in_cksum.o ipproto.o pcap-util.o
prefs.o print.o ps.o ptvcursor.o reassemble.o ringbuffer.o util.o xdlc.o
xmlstub.o register.o
>From the experience I acquired developping zethereal, I see some points
that need to be fixed to easily add new frontends. I've been doing a kind
of wishlist during my experiments, emphasing on what prevented me to do
things quickly.
Don't misunderstand me, the list that follow only focus on problems.
Ethereal is really a great project :)
- put every packet-*.c sources in their own directory !
- make a libpacket from packet-*.o
- lot of code about packet capture is generic but is not made available.
A direct consequence is that it is duplicated between ethereal
and tethereal.
An indirect consequence is that it is also duplicated in zethereal.
(if tethereal did not have a main, I could have linked to thetereal.o)
- The simultaneous use of wiretap and libpcap does not help clarity.
There are callbacks, callback wrappers, and so on..
- Lot's of functions seems to be integrated into the UI, like "follow tcp
stream", or masking packet in the UI (I may be wrong)
The abstract is : it lacks a clean API between core functions and UI.
Anyway, don't hesitate to look at the source
(http://www.cartel-securite.fr/pbiondi/zaurus/). It is very short.
