* 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).
