FUNCTIONS

   parse_netstat
       Usage:

        parse_netstat(%args) -> [status, msg, result, meta]

       Parse the output of Linux "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.

       ·   unix => bool (default: 1)

           Whether to parse Unix socket connections.

       Returns an enveloped result (an array).

       First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller
       error, 5xx function error). Second element (msg) is a string containing error message, or
       'OK' if status is 200. Third element (result) is optional, the actual result. Fourth
       element (meta) is called result metadata and is optional, a hash that contains extra
       information.

       Return value:  (any)
