/*
* 2009-09-19: jyoung
*
* New capinfos features
*
* Continue processing additional files after
* a wiretap open failure. The new -C option
* reverts to capinfos' original behavior which
* is to cancel any further file processing at
* first file open failure.
*
* Change the behavior of how the default display
* of all infos is initiated. This gets rid of a
* special post getopt() argument count test.
*
* Add new table output format (with related options)
* This feature allows outputting the various infos
* into a tab delimited text file, or to a comma
* separated variables file (*.csv) instead of the
* original "long" format.
*
* 2011-04-05: wmeier
* behaviour changed: Upon exit capinfos will return
* an error status if an error occurred at any
* point during "continuous" file processing.
* (Previously a success status was always
* returned if the -C option was not used).

* A 64-bit Unix time would be safe for the indefinite future, as
* this variable would not overflow until 2**63 or
* 9,223,372,036,854,775,808 (over nine quintillion) seconds
* after the beginning of the Unix epoch - corresponding to
* GMT 15:30:08, Sunday, 4th December, 292,277,026,596.
*
* So, if we're displaying the time as YYYY-MM-DD HH:MM:SS.SSSSSSSSS,
* we'll have the buffer be large enough for a date of the format
* 292277026596-MM-DD HH:MM:SS.SSSSSSSSS, which is the biggest value
* you'll get with a 64-bit time_t and a nanosecond-resolution
* fraction-of-a-second.
*
* That's 12+1+2+1+2+1+2+1+2+2+2+1+9+1, including the terminating
* \0, or 39.
*
* If we're displaying the time as epoch time, and the time is
* unsigned, 2^64-1 is 18446744073709551615, so the buffer has
* to be big enough for 18446744073709551615.999999999. That's
* 20+1+9+1, including the terminating '\0', or 31. If it's
* signed, 2^63 is 9223372036854775808, so the buffer has to
* be big enough for -9223372036854775808.999999999, which is
* again 20+1+9+1, or 31.
*
* So we go with 39.
