| 15 | * | |||
| 16 | * New capinfos features | |||
| 17 | * | |||
| 18 | * Continue processing additional files after | |||
| 19 | * a wiretap open failure. The new -C option | |||
| 20 | * reverts to capinfos' original behavior which | |||
| 21 | * is to cancel any further file processing at | |||
| 22 | * first file open failure. | |||
| 23 | * | |||
| 24 | * Change the behavior of how the default display | |||
| 25 | * of all infos is initiated. This gets rid of a | |||
| 26 | * special post getopt() argument count test. | |||
| 27 | * | |||
| 28 | * Add new table output format (with related options) | |||
| 29 | * This feature allows outputting the various infos | |||
| 30 | * into a tab delimited text file, or to a comma | |||
| 31 | * separated variables file (*.csv) instead of the | |||
| 32 | * original "long" format. | |||
| 33 | * | |||
| 34 | * 2011-04-05: wmeier | |||
| 35 | * behaviour changed: Upon exit capinfos will return | |||
| 36 | * an error status if an error occurred at any | |||
| 37 | * point during "continuous" file processing. | |||
| 38 | * (Previously a success status was always | |||
| 39 | * returned if the -C option was not used). | |||
