in tvbuff terminology). This is implemented for TVBUFF_REAL and TVBUFF_SUBSET
so far; support for TVBUFF_COMPOSITE is coming soon.
Throw either ReportedBoundsError or BoundsError.
A ReportedBoundsError is reported as "Malformed Frame" since the protocol
stated that a certain number of bytes should be available but they weren't.
A BoundsError is reported as a "Short Frame" since the snaplen was too short.
Register proto_short (BoundsError) and proto_malformed (ReportedBounds)
so searches can be made on "short" and "malformed".

Modify ethernet dissector to catch BoundsError if the attempt to
create next_tvb with the length specified in the ethernet header throws
an exception. In that case, next_tv is created with as many bytes as
are available in the frame.
Both dissect_tr() and dissect_eth() now have TRY blocks, which means
I had to fiddle with 'volatile' and 'static' storage options to get
things right (at least according to gcc).

selected before we started re-colorizing or re-filtering the display, as
when the first row is added to the clist, that may be selected and thus
made the current frame.
This means that we can't find the row corresponding to the
previously-selected frame, if any, by checking as each packet is
colorized/filtered and see whether its "frame_data" structure is equal
to "cf->current_frame", as that'll always say that the first frame in
the display is the selected frame.
Instead, we recored the value of "cf->current_frame" before we do
anything to the clist, have "add_packet_to_packet_list()" return either
the row number of the frame (if it passed the filter and thus was added
to the clist) or -1 (if it didn't pass the filter and thus wasn't added
to the clist), and, after "add_packet_to_packet_list()", if the current
frame is the one that was the selected row, remember its row number (if
any), and, when we're finished colorizing/filtering the display, make
that row the current row if it's not -1 (-1 means that the selected row
didn't pass the filter).
Also, don't do that until after we've thawed the clist, as the vertical
adjustment for the clist doesn't reflect reality until then, and
attempting to go to a given row won't work right until the vertical
adjustment for the clist reflects reality.
Shove all the code to set the selected and focus rows, and to make said
row visible, into a routine, so the "Find Frame" and "Go To Frame" code
can use it as well.

to little-endian shorts - and to convert host-byte-order longs to
little-endian shorts (if the host-byte-order long will fit into a short,
"htoles()" does the right thing; if it doesn't, there is no right thing
to do - perhaps we should return a wiretap error, although, at least at
present, it's unlikely that we'll have packets bigger than 65535 bytes,
so it's unlikely that the values won't fit into a short).

Tethereal was dying on me because err was initialized to some random value.
It was this section of code that would exit even if wtap_loop was successful
(returned TRUE) because err was never initialized or set to anything.
err = load_cap_file(&cf, out_file_type);
if (err != 0) {
dissect_cleanup();
exit(2);
}

Fixed even more errors in LLC dissector. I had inadvertantly used the
wrong tvbuff_t* when calling dissect_data_tvb(). There is no way we are going
to be successful in this tvbuff conversion w/o regression testing. I'm
working on setting up a simple Makefile for regression testing tonight.
That's why I'm finding so many bugs in my LLC conversion.

Fix error in my conversion to tvbuff routines.
Because offset was calculated based on next_tvb, which already knew to
skip 8 bytes, I don't have to use "offset+8" in calls to the next non-tvbuff
dissectors.

Non-tvbuff dissectors create a tvbuff when calling dissect_llc()

Changed short text to be: [Short Frame: %s] where %s is current_proto.

Add exceptions routines.
Convert proto_tree_add_*() routines to require tvbuff_t* argument.
Convert all dissectors to pass NULL argument ("NullTVB" macro == NULL) as
the tvbuff_t* argument to proto_tree_add_*() routines.
dissect_packet() creates a tvbuff_t, wraps the next dissect call in
a TRY block, will print "Short Frame" on the proto_tree if a BoundsError
exception is caught.
The FDDI dissector is converted to use tvbuff's.

only the dissector source files, not the header files; that way you
don't feed the header files to "make-reg-dotc", as "make-reg-dotc" won't
find any registration routines there so there's no point in feeding
header files to it.
Doing so means that we can make "DISSECTOR_OBJECTS" in "Makefile.nmake"
by doing
DISSECTOR_OBJECTS = $(DISSECTOR_SOURCES:.c=.obj)
rather than separately enumerating the object files, as Nmake supports
System V "make"-style substitution.
This should let users who change "DISSECTOR_SOURCES" in one of those
files just copy it to the other file.

Register a "destroy" callback for the "Display Options" window, so that
no matter how it's destroyed, even if it's destroyed by a window manager
close button rather than by clicking the "OK" or "Cancel" button, we
note that fact by clearing the pointer to the current "Display Options"

that we need to pop a new "Display Options" window up.
