* This is a sanity-check test of ACE_SOCK_Dgram_Mcast::join by
* interface name on platforms that support it.
* It retrieves the valid local interface names and attempts to
* perform a multicast join on all interfaces and then on each
* individual interface separately. If IPv6 is enabled, it will
* attempt to join on an IPv6 multicast address as well.
