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


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.


     usage is Net::Interface

NOT Net::Interface::NetSymbols

use Net::Interface qw(


  print NFe qq|@afs



@iffs |;

  if (@iffIN6) {
    print NFe qq|
@iffIN6 populated for BSD flavored systems

:all :afs :pfs :ifs :iffs :iffIN6 :iftype :scope

); |; } else { print NFe qq| :all :afs :pfs :ifs :iffs :iftype :scope

); |; } print NFe q| =head1 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";


  if (exists $fam{AF_INET6}) {
    print NFe q|On systems supporting IPV6, these additional symbols are available which
may be applied to the address I<type> to determine the address attributes.

non EXPORT functions

  • Net::Interface::NetSymbols::NI_ENDVAL();

    Reports the highest symbol value +1 of :all symbols above. Used for testing.

  • Net::Interface::NetSymbols::NI_UNIQUE();

    Returns a hash pointer to the AF_ or PF_ symbol values mapped to their character strings as defined for this architecture.
