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.
