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.
