Detailed Description

A Transport that communicates on a UDP multicast group.

Definition at line 49 of file multicast-udp-transport.hpp.

Constructor & Destructor Documentation

◆ MulticastUdpTransport()

nfd::face::MulticastUdpTransport::MulticastUdpTransport	(	const protocol::endpoint &	multicastGroup,
		protocol::socket &&	recvSocket,
		protocol::socket &&	sendSocket,
		ndn::nfd::LinkType	linkType
	)

Creates a UDP-based transport for multicast communication.

Parameters

multicastGroup	multicast group
recvSocket	socket used to receive multicast packets
sendSocket	socket used to send to the multicast group
linkType	either `ndn::nfd::LINK_TYPE_MULTI_ACCESS` or `ndn::nfd::LINK_TYPE_AD_HOC`

◆ getSendQueueLength()

ssize_t nfd::face::MulticastUdpTransport::getSendQueueLength ( )

finalvirtual

Returns: current send queue length of the transport (in octets)

Return values

QUEUE_UNSUPPORTED	transport does not support queue length retrieval
QUEUE_ERROR	transport was unable to retrieve the queue length
