NAME
       Socket::Multicast6 - Constructors and constants for IPv4	and IPv6
       multicast socket	operations.

SYNOPSIS
	 use Socket::Multicast6	qw(:all);

	 my $ip	= getprotobyname( 'ip' );

	 my $ip_mreq = pack_ip_mreq( inet_aton(	$mcast_addr ), inet_aton( $if_addr ) );

	 my $ipv6_mreq = pack_ipv6_mreq( inet_pton( AF_INET6, $mcast6_addr ), $if_index	);

	 setsockopt( $sock, $ip, IP_ADD_MEMBERSHIP, $ip_mreq )
	   or die( "setsockopt IP_ADD_MEMBERSHIP failed: $!" );

	 setsockopt( $sock, $ip, IP_DROP_MEMBERSHIP, $ip_mreq )
	   or die( "setsockopt IP_DROP_MEMBERSHIP failed: $!" );

	 setsockopt( $sock, $ip, IP_MULTICAST_LOOP, pack( 'C', $loop ) )
	   or die( "setsockopt IP_MULTICAST_LOOP failed: $!" );

	 setsockopt( $sock, $ip, IP_MULTICAST_TTL, pack( 'C', $ttl ) )
	   or die( "setsockopt IP_MULTICAST_TTL	failed:	$!" );

DESCRIPTION
       This module is used to gain access to constants and utility functions
       used when manipulating multicast	socket attributes.

       For simple, object-oriented way of doing	the same thing,	take a look at
       IO::Socket::Multicast6 or IO::Socket::Multicast.

EXPORTS
       By default nothing is exported, you can use the 'ipv4', 'ipv6' and
       'independent' to	export a specific protocol family, or 'all' to export
       all symbols.

FUNCTIONS
       $ip_mreq	= pack_ip_mreq(MCAST_ADDR, IF_ADDR)
       $ip_mreq_source = pack_ip_mreq_source(MCAST_ADDR, SOURCE_ADDR, IF_ADDR)
       $ipv6_mreq = pack_ipv6_mreq(MCAST6_ADDR,	IF_INDEX)

CONSTANTS
       IP_MULTICAST_IF
       IP_MULTICAST_TTL
       IP_MULTICAST_LOOP
       IP_ADD_MEMBERSHIP
       IP_DROP_MEMBERSHIP
       IP_ADD_SOURCE_MEMBERSHIP
       IP_DROP_SOURCE_MEMBERSHIP
       IPV6_MULTICAST_IF
       IPV6_MULTICAST_HOPS
       IPV6_MULTICAST_LOOP
