Typedef Documentation

PacketPriv

typedef union PacketPriv PacketPriv

mbuf private data for NDN packet.

Function Documentation

Packet_Clone()

Packet* Packet_Clone	(	Packet *	npkt,
		PacketMempools *	mp,
		PacketTxAlign	align
	)

Clone packet to new mbufs.

Return values

NULL	allocation failure.

Returns

new mbufs that fulfill align requirements.

Postcondition

npkt is unaffected.

Packet_Parse()

bool Packet_Parse	(	Packet *	npkt,
		ParseFor	parseFor
	)

Parse layer 2 and layer 3 in mbuf.

Parameters

npkt	a uniquely owned, possibly segmented, direct mbuf.
parseFor	see PInterest_Parse and PData_Parse .

Returns

whether success.

Postcondition

If the packet is fragmented, Packet_GetType(npkt) returns PktFragment . Otherwise, same as Packet_ParseL3 .

Packet_ParseL3()

bool Packet_ParseL3	(	Packet *	npkt,
		ParseFor	parseFor
	)

Parse layer 3 in mbuf.

Parameters

npkt	a uniquely owned, possibly segmented, direct mbuf. Its PacketPriv.lpl3 should have been initialized.
parseFor	see PInterest_Parse and PData_Parse .

Returns

whether success.

Postcondition

Packet_GetType(npkt) returns PktInterest , PktData , or PktNack .

One of PInterest , PData , or PNack is initialized.
