This "white" list sub-selects from the allowed interfaces obtained after applying the allow_interfaces_list "white" list and the deny_interfaces_list "black" list.

After allow_multicast_interfaces_list, the deny_multicast_interfaces_list is applied. Multicast output will be sent and may be received over the interfaces in the resulting list.

If this list is empty, all the allowed interfaces will be potentially used for multicast. It is up to the transport plugin to interpret the list of strings passed in.

This property is not interpreted by the RTI Connext core; it is provided merely as a convenient and standardized way to specify the interfaces for the benefit of the transport plugin developer and user.

The caller (user) must manage the memory of the list. The memory may be freed after the DDS::DomainParticipant is deleted.
