Typedef Documentation

Function Documentation

Interest_ModifyGuiders()

Packet * Interest_ModifyGuiders	(	Packet *	npkt,
		InterestGuiders	guiders,
		PacketMempools *	mp,
		PacketTxAlign	align )

Modify Interest guiders.

Parameters

[in]

npkt

original Interest packet.

Returns

cloned and modified Interest packet.

Return values

NULL	allocation failure.

InterestTemplate_Encode()

Packet * InterestTemplate_Encode	(	const InterestTemplate *	tpl,
		struct rte_mbuf *	m,
		LName	suffix,
		uint32_t	nonce )

Encode Interest with InterestTemplate.

Parameters

m	a uniquely owned, unsegmented, direct, empty mbuf. It must have InterestTemplateDataroom buffer size.

Returns

encoded packet, converted from m .

PInterest_Parse()

bool PInterest_Parse	(	PInterest *	interest,
		struct rte_mbuf *	pkt,
		ParseFor	parseFor )

Parse Interest.

Parameters

pkt	a uniquely owned, possibly segmented, direct mbuf that contains Interest TLV.
parseFor	if set to ParseForApp , skip FwHints.

Returns

whether success.

PInterest_SelectFwHint()

bool PInterest_SelectFwHint	(	PInterest *	interest,
		int	i )

Retrieve i-th forwarding hint name.

Returns

whether success.

Precondition

i >= 0 && i < interest->nFwHints

Postcondition

interest->activeFwHint == i

interest->fwHint reflects i-th forwarding hint.
