Note: actually this function is called AFTER UdpSocketImpl::Destroy or UdpSocketImpl::Destroy6 so the code below is unnecessary in normal operations
Note that this piece of code is a bit tricky: when DeAllocate is called, it will call into Ipv4EndPointDemux::Deallocate which triggers a delete of the associated endPoint which triggers in turn a call to the method UdpSocketImpl::Destroy below will will zero the m_endPoint field.

Bind a socket to specific device.
This method corresponds to using setsockopt() SO_BINDTODEVICE of real network or BSD sockets. If set on a socket, this option will force packets to leave the bound device regardless of the device that IP routing would naturally choose. In the receive direction, only packets received from the bound interface will be delivered.
This option has no particular relationship to binding sockets to an address via Socket::Bind (). It is possible to bind sockets to a specific IP address on the bound interface by calling both Socket::Bind (address) and Socket::BindToNetDevice (device), but it is also possible to bind to mismatching device and address, even if the socket can not receive any packets as a result.

Corresponds to socket option MCAST_JOIN_GROUP.
interface | interface number, or 0 |
groupAddress | multicast group address |
Enable reception of multicast datagrams for this socket on the interface number specified. If zero is specified as the interface, then a single local interface is chosen by system. In the future, this function will generate trigger IGMP joins as necessary when IGMP is implemented, but for now, this just enables multicast datagram reception in the system if not already enabled for this interface/groupAddress combination.
This function may be called repeatedly on a given socket but each join must be for a different multicast address, or for the same multicast address but on a different interface from previous joins. This enables host multihoming, and the ability to join the same group on different interfaces.

Read data from the socket.
This function matches closely in semantics to the recv() function call in the standard C library (libc): ssize_t recv (int s, void *buf, size_t len, int flags); except that the receive I/O is asynchronous. This is the primary Recv method at this low-level API and must be implemented by subclasses.
This method is normally used only on a connected socket. In a typical blocking sockets model, this call would block until at least one byte is returned or the connection closes. In ns-3 at this API, the call returns immediately in such a case and returns 0 if nothing is available to be read. However, an application can set a callback, ns3::SetRecvCallback, to be notified of data being available to be read (when it conceptually unblocks); this is an asynchronous I/O model for recv().
This variant of Recv() uses class ns3::Packet to encapsulate data, rather than providing a raw pointer and length field. This allows an ns-3 application to attach tags if desired (such as a flow ID) and may allow the simulator to avoid some data copies. Despite the appearance of receiving Packets on a stream socket, just think of it as a fancy byte buffer with streaming semantics.
The semantics depend on the type of socket. For a datagram socket, each Recv() returns the data from at most one Send(), and order is not necessarily preserved. For a stream socket, the bytes are delivered in order, and on-the-wire packet boundaries are not preserved.
The flags argument is formed by or'ing one or more of the values: MSG_OOB process out-of-band data MSG_PEEK peek at incoming message None of these flags are supported for now.
Some variants of Recv() are supported as additional API, including RecvFrom(), overloaded Recv() without arguments, and variants that use raw character buffers.

Read a single packet from the socket and retrieve the sender address.
Calls Recv(maxSize, flags) with maxSize implicitly set to maximum sized integer, and flags set to zero.
This method has similar semantics to Recv () but subclasses may want to provide checks on socket state, so the implementation is pushed to subclasses.

Send data (or dummy data) to the remote host.
This function matches closely in semantics to the send() function call in the standard C library (libc): ssize_t send (int s, const void *msg, size_t len, int flags); except that the send I/O is asynchronous. This is the primary Send method at this low-level API and must be implemented by subclasses.
In a typical blocking sockets model, this call would block upon lack of space to hold the message to be sent. In ns-3 at this API, the call returns immediately in such a case, but the callback registered with SetSendCallback() is invoked when the socket has space (when it conceptually unblocks); this is an asynchronous I/O model for send().
This variant of Send() uses class ns3::Packet to encapsulate data, rather than providing a raw pointer and length field. This allows an ns-3 application to attach tags if desired (such as a flow ID) and may allow the simulator to avoid some data copies. Despite the appearance of sending Packets on a stream socket, just think of it as a fancy byte buffer with streaming semantics.
If either the message buffer within the Packet is too long to pass atomically through the underlying protocol (for datagram sockets), or the message buffer cannot entirely fit in the transmit buffer (for stream sockets), -1 is returned and SocketErrno is set to ERROR_MSGSIZE. If the packet does not fit, the caller can split the Packet (based on information obtained from GetTxAvailable) and reattempt to send the data.
The flags argument is formed by or'ing one or more of the values: MSG_OOB process out-of-band data MSG_DONTROUTE bypass routing, use direct interface These flags are unsupported as of ns-3.1.
