Looking Up DomainParticipants

The DomainParticipantFactory has these useful operations for retrieving its DomainParticipants:

	get_participants (DDSDomainParticipantSeq & participants)
	DDSDomainParticipant * 
	lookup_participant (DDS_DomainId_t domainId)
	DDSDomainParticipant * 
	lookup_participant_by_name(const char * participant_name)

Note: in the Modern C++ API these operations are freestanding functions rti::domain::find_participants(), dds::domain::find(), and rti::domain::find_participant_by_name() respectively.
