This is currently still disabled, as we cannot pass all required capture flags to the child process (lack of command line parameters).

move another two capture related fields (iface and cfilter) from cfile to capture_opts
also move the handling of capture related command line options from main.c to capture.c, that way a future privilege seperated capture program can use the same code to parse it's command line than Ethereal.
It might be even possible to share this parser code even with Tethereal, didn't took a closer look at this.

they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

This matters for "update of list in real time" (sync_mode) only,
as in normal mode you wouldn't otherwise have the possibility
to stop the capture.
svn path=/trunk/; revision=11194
when the new "Rotate capture file every n second(s)" checkbox or the
-b <# of file>[:<duration>] argument are used, [t]ethereal will skip to the
next ring buffer file if the specified duration has elapsed (even if the
specified capture size is not reached). This is useful when you want to have
separate capture files per hour or day for instance.
I let the autostop filesize parameter mandatory (i.e. the "rotate capture
file after n kilobytes") but this could be no longer strictly necessary when
that new feature is used ...
Another point: it might be interesting to really truncate the file at the
switch and not the closure ... According to user comments and my own real
case tests, I might plan to enhance this point and others (still ring buffer
related) in the future.

Currently Ethereal sets and uses a default directory for reading
and writing, but only in some places. This set of patches extends
the setting of the default directory to the -w option as well as
the -r option, and causes all file dialogs to use and set the
default consistently. (I haven't changed the
Preferences/Printing/File dialog, though, as that's a special
case.)
There's also a fix for a bug where Ethereal was issuing the
message "Ring buffer requested, but capture isn't being saved to
a permanent file" even though a file was specified with -w.
There also appear to be some other cleanups in his patch.

Move the ringbuffer capture options from the "capture_file" structure to
the structure for capture options, as they're a property of an
in-progress capture, not a property of a particular capture file.
svn path=/trunk/; revision=4799
"capture_file" structure - they're a property of an in-progress capture,
not a property of an open capture file. Make them just variables.
The maximum number of packets to be captured should be a variable
separate from the "count" field in the "capture_file" structure - the
latter is a count of the packets in the capture file in question.
Have Boolean variables indicating whether a maximum packet count,
maximum capture file size, and maximum capture duration were specified.
If an option isn't set, and we're doing an "update list of packets in
real time" capture, don't pass the option to the child process with a
command-line argument.
Don't create "stop when the capture file reaches this size" or "stop
when the capture's run for this long" conditions if a maximum capture
file size or a maximum capture duration, respectively, haven't been
specified. Don't test or free a condition if it wasn't created.
Don't allow a 0 argument to the "-c" flag - the absence of a "-c" flag
is the way you specify "no limit on the number of packets".
Initialize the check boxes and spin buttons for the "maximum packets to
capture", "maximum capture size", and "maximum capture duration" options
to the values they had in the last capture. If an option wasn't
specified, don't read its value from the dialog box and set the
variable.
svn path=/trunk/; revision=4795
reading the capture file. Have callers of "wtap_snapshot_length()"
treat a value of 0 as "unknown", and default to WTAP_MAX_PACKET_SIZE (so
that, when writing a capture file in a format that *does* store the
snapshot length, we can at least put *something* in the file).
If we don't know the snapshot length of the current capture file, don't
display a value in the summary window.
Don't use "cfile.snap" as the snapshot length option when capturing -
doing so causes Ethereal to default, when capturing, to the snapshot
length of the last capture file that you read in, rather than to the
snapshot length of the last capture you did (or the initial default of
"no snapshot length").
Redo the "Capture Options" dialog box to group options into sections
with frames around them, and add units to the snapshot length, maximum
file size, and capture duration options, as per a suggestion by Ulf
Lamping. Also add units to the capture count option.
Make the snapshot length, capture count, maximum file size, and capture
duration options into a combination of a check box and a spin button.
If the check box is not checked, the limit in question is inactive
(snapshot length of 65535, no max packet count, no max file size, no max
capture duration); if it's checked, the spinbox specifies the limit.
Default all of the check boxes to "not checked" and all of the spin
boxes to small values.
Use "gtk_toggle_button_get_active()" rather than directly fetching the
state of a check box.

and "Automatic scrolling in live capture" options from the preference
settings for them, so that the preference settings affect the initial
values of those options, but changing those values in a capture don't
affect the preferences, and don't automatically get saved when you save
the preferences.
If we're building without libpcap, don't have an "Automatic scrolling in
live capture" option anywhere.

(by deleting the main window or selecting File->Quit or typing ^Q) while
an "Update list of packets in real time" capture is in progress, we can
abort the capture.
Arrange that "fork_child" is -1 when there is no capture child, so said
routine knows when it can kill the child.
When we exit, kill off any capture child, using that routine, and, if
we're exiting due to a request to delete the main window and, if a read
is in progress (from an "Update list of packets in real time" capture),
don't delete the main window - just set the "Read aborted" flag, so that
the code doing the read will see that flag (it will be called because
the pipe to the capture child is closed due to the child exiting) will
see that and clean up and exit itself.

capturing; if we succeed, display the packet drops count as the "Drops"
value in the status line and as the "Dropped packets" statistics in the
summary dialog box, otherwise don't display it at all.
In Tethereal, attempt to get the packet statistics from libpcap when
capturing; if we succeed, and if there were any dropped packets, print
out the count of dropped packets when the capture finishes.

file to which to write the capture; if it's NULL, create a temporary
file and use that.
Have "-w" set a local variable, which starts out null, and, for "-k"
captures, call "do_capture()" and pass it that local variable as an
argument; this lets you do "-k" without "-w", which makes it use a
temporary file for the capture.
This means "run_capture()" no longer serves a useful purpose, as its
only caller is "do_capture()"; swallow it into "do_capture()".

capture is done; make it do so, and don't bother passing it a "-Q" flag
to tell it to do so.
"capture()" is called in two places; in one place, it's in a child
process, and it shouldn't read in the capture file. Move the reading of
the capture file out of "capture()" itself to the place where we
*should* read in the capture file after it returns. Also, have it
return an indication of whether it succeeded or failed, so we know
whether we should read in the capture file.

process for a sync mode or fork mode capture.
Have that flag control whether we do things that *only* the parent or
*only* the child should do, rather than basing it solely on the setting
of "sync_mode" or "fork_mode" (or, in the case of stuff done in the
child process either in sync mode or fork mode, rather than basing it on
the setting of those flags at all).
Split "do_capture()" into a "run_capture()" routine that starts a
capture (possibly by forking off and execing a child process, if we're
supposed to do sync mode or fork mode captures), and that assumes the
file to which the capture is to write has already been opened and that
"cf.save_file_fd" is the file descriptor for that file, and a
"do_capture()" routine that creates a temporary file, getting an FD for
it, and calls "run_capture()".
Use "run_capture()", rather than "capture()", for "-k" captures, so that
it'll do the capture in a child process if "-S" or "-F" was specified
("do_capture()" won't do because "-k" captures should write to the file
specified by the "-w" flag, not some random temporary file).
For child process captures, however, just use "capture()" - the child
process shouldn't itself fork off a child if we're in sync or fork mode,
and should just write to the file whose file descriptor was specified by
the "-W" flag on the command line.
All this allows you to do "ethereal -S -w <file> -i <interface> -k" to
start a sync mode capture from the command line.
