Net::Interface::NetSymbols(3)

NAME
Net::Interface::NetSymbols - AF_ PF_ IFxxx type symbols

SYNOPSIS
This module is built for this specific architecture during the make process using inst/netsymbols.pl. Do not edit this module, edit inst/netsymbols.pl instead.

This module contains symbols arrays only for use by Net::Interface, in all other respects it is NOT functional. It contains documentation and data arrays for this specific architecture.

NOTE:    WARNING !!

     usage is Net::Interface

NOT Net::Interface::NetSymbols

DESCRIPTION
All of the AF_XXX and PF_XXX symbols available in local "sys/socket.h" plus usual aliases for AF_LOCAL i.e. (AF_FILE AF_UNIX PF_LOCAL PF_FILE PF_UNIX)

All of the IFxxxx and IN6_IF symbols in "net/if.h, netinet/in.h, netinet/in_var.h" and their includes.

Symbols may be accessed for their numeric value or their string name.

  i.e.  if ($family == AF_INET)
            do something...

    or  print AF_INET
    will product the string "inet"

The same holds true for:

        printf("family is %s",AF_INET);
    or  sprint("family is %s",AF_INET);

To print the numeric value of the SYMBOL do:

        print (0 + SYMBOL), "\n";

On systems supporting IPV6, these additional symbols are available which may be applied to the address type to determine the address attributes.

    IPV6_ADDR_ANY               unknown
    IPV6_ADDR_UNICAST           unicast
    IPV6_ADDR_MULTICAST         multicast
    IPV6_ADDR_ANYCAST           anycast
    IPV6_ADDR_LOOPBACK          loopback

    IPV6_ADDR_SITELOCAL         site-local
    IPV6_ADDR_COMPATv4          compat-v4
    IPV6_ADDR_SCOPE_MASK        scope-mask
    IPV6_ADDR_MAPPED            mapped
    IPV6_ADDR_RESERVED          reserved
    IPV6_ADDR_ULUA              uniq-lcl-unicast
    IPV6_ADDR_6TO4              6to4
    IPV6_ADDR_6BONE             6bone
    IPV6_ADDR_AGU               global-unicast
    IPV6_ADDR_UNSPECIFIED       unspecified

    IPV6_ADDR_ORCHID            orchid
    IPV6_ADDR_NON_ROUTE_DOC     non-routeable-doc

    if ($type & IPV6_ADDR_xxxx) {
        print IPV6_ADDR_xxxx,"\n";
    }

These symbols may be equated to the scope of the address.
