NAME
    Socket::More::Interface - Query network interfaces of your system

SYNOPOSIS
      use v5.36;
      use Socket::More::Interface;

      # Return a list of interface structures (hashes)
      my @interfaces=getifaddrs();


      # Lookup the interface index from its name
      my $index=if_nametoindex($name);
  
      # Lookup the interface name from its index
      my $name=if_nametoindex($index);

      # Get the key/value array of names and indexes
      @kvpairs=if_nameindex;

DESCRIPTION
    Simple wrapper to library calls. Consult you man page for what they do.
    "getifaddrs", "if_nametoindex", "if_indextoname" and "if_nameindex" are
    exported by default.

API
  getifaddrs
            my @interfaces=getifaddrs;

    Queries the OS via "getifaddr" for the list of interfaces currently
    active. Returns a list of hash references representing the network
    interfaces. The keys of these hashes include:

    name
        The text name of the interface

    flags
        Flags set on the interface

    addr
        Packed sockaddr structure suitable for use with "bind"

    netmask
        Packed sockaddr structure of the netmask

    dstmask
        Packed sockaddr structure of the dstmask

  if_nametoindex
            my $index=if_nametoindex($name);

    Returns the index of an interface by name. If the interface is not
    found, returns 0 and sets $! with error code.

  if_indextoname
            my $name=if_indextoname($index);

    Returns the name of an interface by index. If the index does not
    represent an interface, "undef" is returned and sets $! with error code

  if_nameindex
            my @pairs=if_nameindex;

    Returns a list of key value pairs. The key is the interface index, and
    the value is the name of the interface.

    Return "undef" on error and sets $! with error code.

TODO
    Network interface queries for byte counts, rates.. etc
    Expand address family types support(i.e link)
    Network change events/notifications
