This means the data stream name pointer for the item in question is

Use that for some "uses the value from the matching request" fields in

"proto_item_set_text()" except that it appends the result of the

but, before you set the text, you throw an exception while putting stuff
under the subtree, you end up with an absolutely blank protocol tree
item, which is really gross. Instead of calling
"proto_tree_add_notext()", call "proto_tree_add_text()" with at least a
minimal label - yes, it does mean you do some work that will probably be
unnecessary, but, absent a scheme to arrange to do that work if it *is*
necessary (e.g., catching exceptions), the alternative is an ugly
protocol tree display.

fractions-of-a-second (the units of which are either milliseconds or
microseconds, specified by a Boolean argument), and formats it into a
"DD days, HH hours, MM minutes, SS seconds" using a buffer supplied to
it. Have "time_secs_to_str()" and "time_msecs_to_str()" both use it.
Also, have it correctly handle the case of SS being > 0 but < 1 (which
"time_msecs_to_str()" didn't do).
Rename "rel_time_to_str()" to "rel_time_to_secs_str()", and add a
"rel_time_to_str()" routine that takes a "struct timeval" and hands its
seconds and microseconds values to "time_secs_to_str_buf()". Use
"rel_time_to_secs_str()" to format FT_RELATIVE_TIME values for now; we
might want to use "rel_time_to_str()" for them, though, or make it an
option (either a user option, or a per-field option, using the field
that also holds BASE_ values).

a "Match Selected" on it - we can't do a "Match Selected" if the field
has no value (e.g., FT_NULL) and has a length of 0.
If we unselect the current packet, we don't have a protocol tree, so we
don't have a currently selected field - clear the "Match Selected" menu
item and the display in the status line of information about the
currently selected field.
Move the low-level statusbar manipulation into "gtk/main.c", in routines
whose API doesn't expose anything GTK+-ish.
"close_cap_file()" calls one of those routines to clear out the status
bar, so it doesn't need to take a pointer to the statusbar widget as an
argument.
"clear_tree_and_hex_views()" is purely a display-manipulating routine;
move it to "gtk/proto_draw.c".
Extract from "tree_view_unselect_row_cb()" an "unselect_field()" routine
to do all the work that needs to be done if the currently selected
protocol tree row is unselected, and call it if the currently selected
packet list row is unselected (if it's unselected, there *is* no
protocol tree, so no row can be selected), as well as from
"tree_view_unselect_row_cb()".
Before pushing a new field-description message onto the statusbar, pop
the old one off.
Get rid of an unused variable (set, but not used).

argument, have it just return; this allows dissectors that don't
explicitly check for a null protocol-tree argument to pass the
protocol-tree argument to "proto_tree_add_XXX()" routines - which means
they'll get a null pointer back if the protocol-tree argument is null
because we're not constructing a protocol tree - and then later use
"proto_item_set_len()" without having to check for a null
protocol-tree-item pointer.

1. Fix an off-by-one error when finding the field. This only showed up
if the selected byte had no field of its own and was only designated
as part of the parent protocol (like the 00-padding at the beginning of
TCP options).
2. Fix an off-by-one error when clicking on a character in the second
half of the "text dump" portion of the hex dump. I forgot about the

When a user clicks on a hex digit or on the corresponding character
(the "text dump" portion) in the hex dump, find the field in the
proto_tree that the byte corresponds to, expand the GtkCTree so that
the field is viewable, select the field, and center it vertically.

Remove type FT_TEXT_ONLY in favor of FT_NONE, and have protocols registered

be loaded and their initialization routines called in right after we
call the initialization routines for built-in dissectors, but don't call
their handoff registration routines yet, and then call the handoff
registration routines right after calling the handoff registration
routines for built-in dissectors.
Do all that in "proto_init()", rather than "epan_init()".
That way, we call all dissector registration routines together, and then
call all dissector handoff registration routines together; all the
registration routines are called before any handoff registration
routines, as is required, and, as "proto_init()" is called by
"epan_init()" before "dfilter_init()" is called, all filterable fields
have been registered before "dfilter_init()" is called, and no plugins
have to call "dfilter_init()" themselves to get their fields registered.
Remove pointers to "dfilter_init()" and "dfilter_cleanup()" from the
plugin address table, as plugins shouldn't be calling them any more, and
remove calls to them from plugins.

and so on (although we're not yet using it in all those places).

string formatter, like "format_text()", and, as "tvbuff.c" now calls it
(*vide infra*), we don't want to have to make "tvbuff.c" drag "packet.h"
in just to declare "bytes_to_str()". It's now declared in "strutil.h",
so include it in modules that use "bytes_to_str()" and weren't already
including it.
Add a "tvb_bytes_to_str()" wrapper that calls "tvb_get_ptr()" to get a
pointer to a chunk of N bytes at a given offset in a tvbuff and then
hands that chunk to "bytes_to_str()". Convert the code that was doing
that to use "tvb_bytes_to_str()" instead (which caught what I suspect is
a bug in the Q.2931 dissector, where it was handing an offset of 0 to
"tvb_get_ptr()" - a cut-and-pasteo, I think).
