It is simply the count of the number of seconds in the specified period of time. It will generate a date-based serial number. Or you can pass a positive number to add to the current serial number. If you wish your output formatted differently, you can pass the output of dump to your favourite templating module. Returns a count of the number of unparsable lines from the last time a zone file was parsed. If no zone file has been parsed yet, returns 0.

If not set, DNS::ZoneParse will croak when an unparsable line is encountered, but will continue to parse the file. Each time an unparsable line is encountered, an internal counter is incrememnted. The callback is passed four parameters, a reference to the DNS::ZoneParse object which is doing the parsing, the text of the line that is unable to be parsed, the text of the reason the line could not be parsed, and the text of the last successfully parsed line.

Each time an unparsable line is encountered, an internal counter is incrememnted. The callback is passed four parameters, a reference to the DNS::ZoneParse object which is doing the parsing, the text of the line that is unable to be parsed, the text of the reason the line could not be parsed, and the text of the last successfully parsed line.

The method takes a single optional parameter, a code reference to the function that will be called when an unparsable line is reached. Returns a reference to the last callback. If passed an undefined value, a reference to the current callback is returned. If passed any other value, undef is returned.

Furthermore, parsing large zone files with thousands of records can use lots of memory - some people have requested a callback interface. BUGS I can squash more bugs with your help. Please let me know if you spot something that doesn't work as expected.

To the left of the split's sign, you'll see that I'm assigning a group of three different variables. These represent one for each column of the line. Finally, each variable that has been split from the file's line is printed separately so that you can see how to access each column's data individually.

The output of the script should look something like this:. Although in this example we're just printing out the data, it would be trivially easy to store that same information parsed from a TSV or CSV file, in a full-fledged database. Actively scan device characteristics for identification.
