Dumpcap: print closed ring-buffer file names
This proposal adds a new option '-b printname:<filename>' to dumpcap. If
used, dumpcap will print the name of each ring buffer file it creates
after it is closed. Allows the use of '-'/'stdout' and 'stderr'.
Use case: Since the file name is printed after the file is closed for
writing, an automated capture process can do something like the
following with the guarantee that the file in question will not be
changed.
dumpcap -i eth0 -b files:2 -b printname:stdout [-b ...] | \
while read cap_file_name ; do
# Do something with $cap_file_name
done
This sort of scripting is difficult in dumpcap's current form. Dumpcap
prints the names of new files to stderr as it *opens* them, so a script
attempting to use this must sleep for "-b duration:value" seconds plus
some fudge time to be sure it's getting a closed, unchanging file.
