FUNCTIONS
parse_netstat
Usage:
parse_netstat(%args) -> [$status_code, $reason, $payload, \%result_meta]
Parse the output of Windows "netstat" command.
Netstat can be called with "-n" (show raw IP addresses and port numbers instead of
hostnames or port names) or without. It can be called with "-a" (show all listening and
non-listening socket) option or without. And can be called with "-p" (show PID/program
names) or without.
This function is not exported by default, but exportable.
Arguments ('*' denotes required arguments):
• output* => str
Output of netstat command.
• tcp => bool (default: 1)
Whether to parse TCP (and TCP6) connections.
• udp => bool (default: 1)
Whether to parse UDP (and UDP6) connections.
Returns an enveloped result (an array).
First element ($status_code) is an integer containing HTTP-like status code (200 means OK,
4xx caller error, 5xx function error). Second element ($reason) is a string containing
error message, or something like "OK" if status is 200. Third element ($payload) is the
actual result, but usually not present when enveloped result is an error response
($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is
optional, a hash that contains extra information, much like how HTTP response headers
provide additional metadata.
Return value: (any)

CONTRIBUTING
To contribute, you can send patches by email/via RT, or send pull requests on GitHub.
Most of the time, you don't need to build the distribution yourself. You can simply modify
the code, then test via:
% prove -l
If you want to build the distribution (e.g. to try to install it locally on your system),
you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR,
Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla-
and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug
and can be reported to me.
