Detailed Description

Link local address.

LLSocketAddress wraps the standard sockaddr_ll data type. An LLSocketAddress provides quite some information, only part of which is necessary for sending packets. The LLSocketAddress class only allows changing those fields which need to be changed. The other fields are read-only. They are filled by the operating system when receiving a packet

Member Enumeration Documentation

◆ PktType

enum senf::LLSocketAddress::PktType

Valid pkttype() values.

These are the possible values returned by pkttype()

Enumerator
Undefined
Host	Packet destined for this host
Broadcast	Packet sent to the broadcast address
Multicast	Packet sent to a (link local) multicast address
OtherHost	Packet sent to another host (promisc)
Outgoing	Packet sent out from this host

Constructor & Destructor Documentation

◆ LLSocketAddress() [1/5]

senf::LLSocketAddress::LLSocketAddress ( )

Create empty address.

◆ LLSocketAddress() [2/5]

senf::LLSocketAddress::LLSocketAddress	(	unsigned	proto,
		std::string const &	iface = `""`
	)

explicit

Create address for bind()

This constructs an LLSocketAddress valid for calling PacketSocketHandle::bind() with.

Parameters

[in]	proto	Protocol (Ethertype) to listen for
[in]	iface	Interface name to bind to

◆ LLSocketAddress() [3/5]

senf::LLSocketAddress::LLSocketAddress ( std::string const & iface )

explicit

Create address for bind()

This constructs an LLSocketAddress valid for calling PacketSocketHandle::bind() with.

Parameters

[in] iface Interface name to bind to

Exceptions

UnknownInterfaceException if iface is not a valid interface name.

◆ LLSocketAddress() [4/5]

senf::LLSocketAddress::LLSocketAddress	(	MACAddress const &	addr,
		std::string const &	iface = `""`
	)

explicit

Create address valid to send raw packets.

Addresses created with this constructor are valid for use with PacketSocketHandle::sendto() on a SOCK_DGRAM packet socket.

Parameters

addr	Address to send data to
iface	Interface to send packet from

Exceptions

UnknownInterfaceException if iface is not a valid interface name.

Return interface name.

Definition at line 34 of file LLAddressing.cc.

◆ interface() [2/2]

void senf::LLSocketAddress::interface ( std::string const & iface )

Change interface.

Exceptions

UnknownInterfaceException if iface is not a valid interface name.

Definition at line 46 of file LLAddressing.cc.

◆ operator=()
