and to fork off and run a separate copy of "ethereal" for "-S" and "-F"
captures or just call "capture()" otherwise, out of "gtk/capture_dlg.c"
and into a routine in "capture.c".
If the attempt to create said temporary capture file fails, pop up a
dialog box and don't do the capture.
Have the child capture process send a message upstream after it either
successfully starts the capture and syncs out the header of the capture
file, or fails to start the capture; the message indicates whether it
succeeded or failed, and, if it failed, includes a failure message.
This:
avoids the use of a signal, and thus means we don't have to
worry about whether to capture the signal, or whether to start
or stop capturing depending on whether this particular capture
is in sync mode or not;
lets us pop up the message box for the error in the parent
process if we're in sync mode, rather than doing it in the
child, which didn't work well.
Add a check button to the Capture/Start dialog box, so that we can
control, for each capture, whether it's to be done in sync mode or not.

gzip. The zLib library is used for this purpose. If zLib is not available
(or it's use is disabled by the --disable-zlib option to configure), you
can still compile Ethereal but it will be unable to read compressed capture
files.
IMPORTANT:
Now all file accesses to capture files should be done through special macros.
Specifically, for any use of the following functions on capture files, replace them.
The arguments for the right-side functions are exactly the same as for the
original stdio functions.
fopen file_open
fdopen filed_open
fread file_read
fwrite file_write
fseek file_seek
fclose file_close
ferror file_error

prints the protocol tree, and summary prints the fields in the summary
clist, with a header line at the beginning of the printout.
Print only packets selected by the current packet filter.
Just have "ARP" and "RARP" in the "Protocol" field for ARP packets;
whether it's a request or a reply can be seen in the "Info" field.
Add to the "Frame" section of the protocol tree the time between the
current packet and the previous displayed packet, and the packet number.
Have FT_RELATIVE_TIME fields be a "struct timeval", and display them as
seconds and fractional seconds (we didn't have any fields of that type,
and that type of time fits the delta time above).
Add an FT_DOUBLE field type (although we don't yet have anything using
it).
