probably fail (as you're probably out of disk space or over quota), and,
even if they don't, the file's going to be corrupt in any case.
(Hopefully that's sufficient to avoid warnings that we're ignoring the
result of fwrite().)
For fread(), check for errors or short reads, at least in all cases
where we have a provision for failing if the read fails.

to do this, I've added file_util.h to wiretap (would file_compat.h be a better name?), and provide compat_macros like eth_open() instead of open(). While at it, move other file related things there, like #include <io.h>, definition of O_BINARY and alike, so it's all in one place.
deleted related things from config.h.win32
As of these massive changes, I'm almost certain that this will break the Unix build. I'll keep an eye on the buildbot so hopefully everything is working again soon.

I've done more than a day to change the timestamp resolution from microseconds to nanoseconds. As I really don't want to loose those changes, I'm going to check in the changes I've done so far. Hopefully someone else will give me a helping hand with the things left ...
What's done: I've changed the timestamp resolution from usec to nsec in almost any place in the sources. I've changed parts of the implementation in nstime.s/.h and a lot of places elsewhere.
As I don't understand the editcap source (well, I'm maybe just too tired right now), hopefully someone else might be able to fix this soon.
Doing all those changes, we get native nanosecond timestamp resolution in Ethereal. After fixing all the remaining issues, I'll take a look how to display this in a convenient way...
As I've also changed the wiretap timestamp resolution from usec to nsec we might want to change the wiretap version number...

filter as an argument on the command line and have a dialog box to enter
the display filter through the GUI. Use it for all stats using
"gtk_tap_dfilter_dlg_cb()".
Add a top-level "stat_menu.h" file to declare "REGISTER_STAT_GROUP_E"
for the benefit of the declaration of "register_dfilter_stat()" in the
top-level "tap_dfilter_dlg.h". Rename the "stat_menu.h" in the gtk
directory to "gtk_stat_menu.h", so as not to have two headers with the
same name.
Get rid of headers not declaring any functions not being used in the
module.

and "Statistics" menu items into "stat.h" and "stat.c", to separate them
from the core tapping APIs. A tap could conceivably not register as a
"-z" command-line argument or "Statistics" menu item, and a stat could
conceivably not be implemented as a tap, and dissectors that implement
tapping points don't need the UI-related stuff from "stat.h", they just
want the tap-related stuff in <epan/tap.h>.

it's used to register a callback for a tap listener invoked if the
specified command line argument is specified to the "-z" flag.
Move it, along with routines to:
look up a "-z" argument in the table constructed by
"register_tap_listener_cmd_arg()" and either save the full
argument to "-z" and the corresponding listener if it's found or
return a failure indication if it isn't;
list the available tap listeners;
call the "init" routines for the tap listeners saved in the
table above;
and have Ethereal and Tethereal use those routines.

This includes: all functions in file.h now have a cf_ prefix, will have doxygen tags, will have the capture_file *cf as the first parameter and I tried to generalize the return values for non trivial functions.
Hopefully, I didn't introduced any new bugs, as I had to change a lot of files...

all indicate that {message,alert} boxes are modal, at least for the
window to which they apply. (Presumably the idea is that not forcing
the user to pay attention to the alert box, and allowing more than one
alert box to be up for a given window, causes more problems than not
letting the user do stuff to that window in order to figure out what the
underlying problem is or figure out what to do to fix it - the message
should be sufficient, in most if not all cases, to let you know what the
problem is.)
Make "simple_dialog()" unconditionally make the alert box modal, and get
rid of ESD_TYPE_MODAL. XXX - we need to make it possible to make an
alert box modal for a given window, rather than just the top-level
window.

is TRUE if all the RTP raw data is present in the tvbuff and FALSE
otherwise. If it's not all present, also set "info_data_len" to 0 and
"info_data" to NULL.
In the RTP Analysis "Save Payload..." operation, check the
"info_all_data_present" flag and fail if it's not set, and use
"rtpinfo->info_data" and "rtpinfo->info_payload_offset" to get at the
payload, rather than using "cfile.pd", as the latter doesn't necessarily
refer to the current frame data.
Note that the RTP Streams save operation should also check the
"info_all_data_present" flag.

"simple_dialog()"; NULL might be #defined to be a pointer expression on
some platforms, causing compiler warnings (and, on platforms where a
null pointer doesn't have all its bits 0, possibly causing misbehavior,
although I don't think there are any such platforms on which Ethereal
runs).
Don't allow 0 as button mask argument to "simple_dialog()".
Squelch a compiler warning.
Report fatal problems as errors, not warnings.
Report file I/O errors with "file_open_error_message()".
Report file write errors (including those reported by "close()", e.g.
some errors writing to an NFS server) when saving raw packet data to a

- made streams list sortable by column
- added a button "Find Reverse" that finds the reverse stream to the
selected forward stream. (If different reverse streams available,
pushing the button repeatedly will cycle through all of them,
one after the other.)
- tidied up lots of superflous code.
Also get rid of a const pointer cast warning, and remove the _U_ attribute
from rtpstream_reset().
svn path=/trunk/; revision=9863
- added a pointer to raw rtp data to _rtp_info that can be used by
taps;
- RTP packets are passed to the tap queue only if they are not
error packets (so that you don't need to filter out ICMP
packets)
- use that pointer in rtp_stream, so it handles packets with
padding, and should handle RTP packets fragmented across
lower-level packets
- moved rtp_stream from tap sources to normal files
(prevents on-start-up registration of the rtp_stream tap
listener)
- rtp_stream tap gets registered/unregistered with the "RTP
Streams" dialog box
i.e. the tap is registered as long as the dialog box is open.
Alternatively, it is de-/registered on demand if RTP Analysis is
called directly on a packet.
- rtp_stream tap listener no longer uses a filter in dissection
` and does not need to have a proto tree being built.
(performance increase)
- fixed: RTP Streams list will get updated in real time if the
dialog box is open while a redissection takes place.
svn path=/trunk/; revision=9051
- can now handle streams with different payload types
- detects payload changes
- detects comfort noise (PT=13 and 19)
- status line now shows: sequence errors, payload changes,
comfort noise (if any)
- uses colours for lines with status != "Ok"
- new button "next": jumps to next line with status != "Ok"
(starting from selected line)
- fixed: wrong jitter calculation (bug from tap_rtp)
- fixed: marker was not shown on first packet or erroneous
packets (bug from tap_rtp)
- code refactored to improve readability and reuse
