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

Constructor & Destructor Documentation

senf::LLSocketAddress::
LLSocketAddress	()

Create empty address.

Definition at line 34 of file LLAddressing.cci.

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

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

Definition at line 38 of file LLAddressing.cci.

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

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.

Definition at line 45 of file LLAddressing.cci.

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

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.
