Detailed Description
Raw Packet-Socket access (Linux)
- Socket Handle typedefs:
- PacketSocketHandle (ProtocolClientSocketHandle)
- Policy Interface:
- ClientSocketHandle::read(), ClientSocketHandle::readfrom(), ClientSocketHandle::writeto(), ClientSocketHandle::bind(), ClientSocketHandle::local()
- Address Type:
- LLSocketAddress
The PacketSocketProtocol provides access to the linux packet socket API. This API gives access to the low level network packets. The packet socket allows read() and write() operations. The PacketSocketProtocol has no concept of a server socket.
This class is utilized as the protocol class of the ProtocolClientSocketHandle via the Socket Handle typedefs above.

Member Function Documentation
◆ init_client()
| void senf::PacketSocketProtocol::init_client | ( | SocketType | type = RawSocket, |
| int | protocol = -1 |
||
| ) | const |
Create packet socket.
The new socket will receive all packets of the given IEEE 802.3 protocol. The socket will receive all packets, if protocol is -1.
If type is RawSocket, the packet will include the link-level header (the Ethernet header). Sent packets must already include a well formed ll header.
If type is DatagramSocket, the link level header will not be part of the packet data. The ll header will be removed from received packets and a correct ll header will be created on sent packets.
- Parameters
-
[in] type socket type [in] protocol IEEE 802.3 protocol number
- Note
- This member is implicitly called from the ProtocolClientSocketHandle::ProtocolClientSocketHandle() constructor
