building in Cygwin's pretend-it's-UNIX environment, we need to treat the
platform as Windows.
Get rid of the BSD #define - just check for the platforms on which we
mustn't use "select()".

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.

used for the DOS-based ATM Sniffer. (That's not a great name, but I
couldn't think of a better one.)
Add a new WTAP_ENCAP_ATM_PDUS_UNTRUNCATED encapsulation type for capture
files where reassembled frames don't have trailers, such as the AAL5
trailer, chopped off. That's what at least some versions of the
Windows-based ATM Sniffer appear to have.
Map the ATM capture file type for NetXRay captures to
WTAP_ENCAP_ATM_PDUS_UNTRUNCATED, and put in stuff to fill in what we've
reverse-engineered, so far, for the pseudo-header; there's more that
needs to be done on it, e.g. getting the channel, AAL type, and traffic
type (or inferring them if they're not in the packet header).

It can sometimes happen that capturing is stopped just after Ethereal
has switched to a new ring buffer. The result is that no frames
are displayed. The patch to ringbuffer.c displays the previous ring
buffer if the current buffer is empty on close.
The patch to capture.c fixes a bug where an error return from
ringbuf_wtap_dump_close was ignored, and tidies up the code around
the call.
svn path=/trunk/; revision=6315
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.

hopefully not cause any problems under MSVC++, as those files using
struct timeval still include wtap.h, which still includes winsock2.h.

Allow "-" as the output file name in Wiretap, referring to the
standard error.
Optimize the capture loop.
Fix some of the error-message printing code in Ethereal and Tethereal.
Have Wiretap check whether it can seek on a file descriptor, and pass
the results of that test to the file-type-specific "open for output"
routine. Have the "open for output" routines for files where we need to
seek when writing the file return an error if seeks don't work.

In sync mode, if the capture file written by the child can't be

error messages.
This patch fixes the problem.

working on MacOS X.
It appears that the underlying problem with the timeout was that we
weren't treating MacOS X as a BSD, and the "select()" we were doing
presumably wasn't working as it doesn't work on BPF devices on many
BSDs; the workaround no longer appears to be necessary, with Michael's
fix to treat MacOS X as BSD.
(Presumably a select timeout with "tv_usec" set to 1000*1000
microseconds was treated as an error, or otherwise treated in such a way
that it didn't block waiting for the BPF device to say it could be
read.)

BPF, in at least some OS versions, acts like the other BPFs in some
versions of other BSDs, and doesn't work with "select()".

This fixes some bugs:
1. With the -S option under Linux, Capture/Stop or ^E was
ignored until the next packet was read. This is because
capture.c wasn't checking for EINTR from select(), which is
returned when the child receives SIGUSR1 from the parent.
2. When reading from a pipe, a spurious error message from
pcap_open_live() was written to stderr.
3. Error messages from the child in Sync mode were displayed in
a Warning alert box.
Also, there's a new subroutine, popup_errmsg(), to replace
several instances of duplicate code.

unused.
Put in a comment to note that if we fail to open the interface either as
a device or as a pipe, we report the error from the failed
"pcap_open_live()" (which explains why "pipe_open_live()" doesn't return
an error string).

returns radio information such as signal strength, channel, and data
rate in a pseudo-header. Add that pseudo-header.
Use the "802.11 with radio information" encapsulation type for Wireless
Sniffer files; extract the radio information from where it appears to be
in the header.
Add dissector code for that encapsulation type.
Fix an error in the code to put radio information into the AiroPeek
tree.
Make the "wrapped" flag for NetXRay/Windows Sniffer captures a

Move the ringbuffer capture options from the "capture_file" structure to
