Detailed Introduction

The deIPcK (Digilent Embedded IP stack for chipKIT) library is a wrapper for the deIP stack. The library is said to be mostly compliant with RFC 1122/793. It can be used to create a TCP or UDP client or server. You can use the deIPcK library to create client and servers for both the TCP and UDP protocols.

Introductory Programs

TCPEchoServer

This is a simple sketch to illistrate a simple TCP Server.

The following parameters apply to all overloaded methods of tcpConnect. tcpConnect Starts the connection process to connect a TCPSocket to a remote host. In itself, this does not "finish" the connection, to determine if the connection has successfully been made, IsConnected should be called.

Name	Description
szRemoteHostName	A pointer to a zero terminated string holding the hostname of the to connect to. This will call the underlying DNS service to r to an IPv4 address. If no DNS servers were specified or DHCP intialize DEIPcK, then the DNS lookup will fail. The hostname until IsConnected succeeds, or a hard failure status is retur IsStatusAnError can be used to identify a hard failure status
remotePort	The port on the remote machine you want to connect too.
remoteIP	The IPv4 address of the remote machine you want to connect to. This will call the underlying APR service to resolve the IP address to a MAC.
epRemote	A IPEndPoint containing the remote IPv4 address and remote port to connect to. This will call the underlying APR service to resolve the IP address to a MAC.
pStatus	A pointer to receive the connect status. This is a status and may not be a failure. Use IsStatusAnError to determine if this is a hard failure.

Reads an array of bytes from the socket buffer (and removes the bytes from the socket). rgbRead is A pointer to a buffer to receive the bytes. Returns the actual number of bytes read. 0 is returned if no bytes were read or an error occured. This call is safe to make without checking the connection status.

writeByte(byte bData)

int writeByte(byte bData);

Write a byte out on the TcpIP connection. bData is the byte to write out. Returns 1 if the byte was written. 0 is returned if no bytes were written or an error occured. This call is safe to make without checking the connection status. However, This is a very costly call to make as the byte is flushed out on to the wire. No caching of intermediate written bytes are done because it is impossible to know if the caller only wants to write 1 byte, or has a sequence to write. If more than 1 byte is to be put on the wire in one packet, Write should be used.

writeByte(byte bData, IPSTATUS * pStatus)

int writeByte(byte bData, IPSTATUS * pStatus);

Write a byte out on the TcpIP connection. bData is the byte to write out. pStatus is A pointer to receive the status of the call, usually the connection status.

rgbWrite	A pointer to an array of bytes to write out.
cbWrite	The number of bytes to write out.
msBlockMax	The maximum amount of time that should be spent attempting to write out the buffer. Typically this parameter is not needed and the default value can be used. However, if writing a buffer larger than the internal TcpIP socket buffer, multiple writes will be used to write the whole buffer out and this could take some time depending on the speed of the network and the size of the array. If the timeout occurs before all of the bytes are written, the number of bytes actually written will be returned to the caller and Write will have to be called again to write out the un-written bytes.
pStatus	A pointer to receive the status of the call, usually the connection status.

writeStream(const byte *rgbWrite, size_t cbWrite)

Checks to see how many pending clients are availabe to be accepted. Returns the number of waiting TCPSockets to be accepted.

availableClients(int& cWaiting)

int availableClients(int& cWaiting)

Checks to see how many pending clients are availabe to be accepted. Returns the number of waiting TCPSockets to be accepted.

availableClients(int& cWaiting, IPSTATUS * pStatus)

int availableClients(int& cWaiting, IPSTATUS * pStatus)

Checks to see how many pending clients are availabe to be accepted. Returns the number of waiting TCPSockets to be accepted.

isListening(void)

int isListening(void)

isListening(IPSTATUS * pStatus)

int isListening(IPSTATUS * pStatus)

acceptClient(int index)

TCPSocket * acceptClient(int index);

Removes a pending TCPSocket by accepting it from the server. pTCPSocket is A pointer to a newly constructed client TCPSocket. index is the zero based index of the client you want to accept. index must be less than AvailableClients. pStatus is A pointer to receive the status of AcceptClient. Yhis call should be made immediately after AvailableClients or GetAvailableClientsRemoteEndPoint. o not run PeriodicTasks between AvailableClients and this call because the client count could change. In order to keep the indexes within the range of AvailableClients and consistent with what returned, do not run AvailableClients or PeriodicTasks inbetween them. That is, do not run any stack task as that would change the AvailableClients count and order.

getAvailableClientsRemoteEndPoint(IPEndPoint& epRemote, int index)

bool getAvailableClientsRemoteEndPoint(IPEndPoint& epRemote, int index);

Returns endpoint information about a TCPSocket waiting to be accepted. pRemoteEP A pointer to an IPEndPoint to receive the remote endpoint information for the client waiting to be accepted. This may be NULL if you don't want the info. pRemoteMAC is A pointer to a MAC to receive the remote MAC address of the client waiting to be accepted. This will be the MAC address as known by ARP and will only have MAC address of machines on your local area network. If the IP is not local, the MAC will most probably be the MAC of your router. This may be NULL if you don't want the info. index is a zero based index and must be less than what AvailableClients returns. It selects the Client within the server list that you want remote endpoint information on. This allows you to determine if you want to accept this endpoint before removing it from the server. It allows you to accept other clients first and out of order. This call should be made immediately after AvailableClients and immediately before AcceptClient so that the servers pending list does not change due to another connection.

getAvailableClientsRemoteEndPoint(IPEndPoint& epRemote)

bool getAvailableClientsRemoteEndPoint(IPEndPoint& epRemote)

getListeningEndPoint(IPEndPoint& epLocal)

bool getListeningEndPoint(IPEndPoint& epLocal);

Gets the endpoint that the server is listening on. This is both the IP and port the server is on. pLocalEP is A pointer to an IPEndPoint to receive the local endpoint information. If false is returned, then *pLocalEP will be garbage.

UDPServer

Constructor

UDPServer()

UDPServer();

Initialize a new UDPServer Instance and specify maximum number of sockets that it will use. Only 1 socket is listening at a time on the port however there may be many sockets pending and accept. Once all sockets are consumed by unaccepted clients UDPServer will stop listening on the port until a client is accepted and a socket opens up.

Public Functions

UDPServer()

bool addSocket(UDPSocket& udpSocket, IPSTATUS * pStatus);

addSocket(UDPSocket& udpSocket)

bool addSocket(UDPSocket& udpSocket)

close(void)

void close(void);

Stops Listening and closes all unaccepted sockets/connections and clears everything back to it's originally constructed state.

availableClients

Checks to see how many pending clients are availabe to be accepted.

This is the workhorse of the UDPServer Class. It will update pending clients if a connection is detected. It will attempt to start listening if a socket comes avalialbe for listening. It will clean up disconnected clients.

acceptClient(void)

UDPSocket * acceptClient(void)

Removes a pending UDPSocket by accepting it from the server.

getAvailableClientsRemoteEndPoint(IPEndPoint& epRemote, int index)

bool getAvailableClientsRemoteEndPoint(IPEndPoint& epRemote, int index);

Returns endpoint information about a UDPSocket waiting to be accepted.

getAvailableClientsRemoteEndPoint(IPEndPoint& epRemote)

bool getAvailableClientsRemoteEndPoint(IPEndPoint& epRemote)

Returns endpoint information about a UDPSocket waiting to be accepted.

getListeningEndPoint(IPEndPoint& epLocal)

bool getListeningEndPoint(IPEndPoint& epLocal);

Gets the endpoint that the server is listening on. This is both the IP and port the server is on.
