|
|
* New capinfos features
|
|
*
|
|
* Continue processing additional files after
|
|
* a wiretap open failure. The new -C option
|
|
* reverts to capinfos' original behavior which
|
|
* is to cancels 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.
