Detailed Description

The Socket class provides TCP or UDP ethernet networking.

To exchange data with a remote IP on the network using UDP, follow these steps:

    1.  Create a Socket instance with the static Create() function.

1. Bind() the Socket to a host IP address and port
2. Exchange data with the Send/Recv functions

Constructor & Destructor Documentation

~Socket()

Socket::~Socket

(

)

Destructor.

Member Function Documentation

Accept()

bool Socket::Accept

(

uint64_t

timeout = 0

)

Accept incoming connections (TCP only).

Parameters

timeout

The timeout (in microseconds) to wait for incoming connections before returning.

Bind() [1/3]

bool Socket::Bind	(	const char *	localIP,
		uint16_t	port
	)

Bind the socket to a local host IP address and port.

Parameters

ipAddress	IPv4 address in string format "xxx.xxx.xxx.xxx"
port	the port number (0-65536), in host byte order. If the port specified is 0, the socket will be bound to any available port.

Bind() [2/3]

bool Socket::Bind

(

uint16_t

port = 0

)

Bind the socket to a local host port, on any interface (0.0.0.0 INADDR_ANY).

Parameters

port	the port number (0-65536), in host byte order. If the port specified is 0, the socket will be bound to any available port.

Bind() [3/3]

bool Socket::Bind	(	uint32_t	localIP,
		uint16_t	port
	)

Bind the socket to a local host IP address and port.

Parameters

hostIP	IPv4 address, in network byte order. If htonl(INADDR_ANY) is specified for the ipAddress, the socket will be bound to all available interfaces.
port	the port number (0-65536), in host byte order. If the port specified is 0, the socket will be bound to any available port.

Connect() [1/2]

bool Socket::Connect	(	const char *	remoteIP,
		uint16_t	port
	)

Connect to a listening server (TCP only).

Parameters

remoteIP

IP address of the remote host.

Connect() [2/2]

bool Socket::Connect	(	uint32_t	remoteIP,
		uint16_t	port
	)

Connect to a listening server (TCP only).

Parameters

remoteIP

IP address of the remote host.

Create()

static Socket* Socket::Create ( SocketType  type )

static

Create.

EnableJumboBuffer()

bool Socket::EnableJumboBuffer

(

)

Enable jumbo buffer.

GetFD()

int Socket::GetFD ( ) const

inline

Retrieve the socket's file descriptor.

GetMTU()

size_t Socket::GetMTU

(

)

Retrieve the MTU (in bytes).

Returns 0 on error.

GetType()

SocketType Socket::GetType ( ) const

inline

GetType.

PrintIP()

void Socket::PrintIP

(

)

const

PrintIP.

Recieve() [1/2]

size_t Socket::Recieve	(	uint8_t *	buffer,
		size_t	size,
		uint32_t *	remoteIP,
		uint16_t *	remotePort,
		uint32_t *	localIP
	)

Recieve packet, with additional address info.

In addition to returning the IP and port of the remote host which sent the packet, this function can also return the local IP and port which the packet was sent to.

Recieve()

Recieve() [2/2]

size_t Socket::Recieve	(	uint8_t *	buffer,
		size_t	size,
		uint32_t *	remoteIP = NULL,
		uint16_t *	remotePort = NULL
	)

Wait for a packet to be recieved and dump it into the user-supplied buffer.

Optionally return the IP address and port of the remote host which sent the packet.

Parameters

buffer	user-allocated destination for the packet
size	size of the buffer (in bytes)
remoteIpAddress	optional output, the IPv4 address of where the packet originated (in network byte order).
remotePort	optional output, the port from where the packet originated (in host byte order).

Returns

the size (in bytes) of the packet sucessfully written to buffer.

Send()

bool Socket::Send	(	void *	buffer,
		size_t	size,
		uint32_t	remoteIP,
		uint16_t	remotePort
	)

Send message to remote host.

SetBufferSize()

bool Socket::SetBufferSize

(

size_t

size

)

Set the rx/tx buffer sizes.

SetRecieveTimeout()

bool Socket::SetRecieveTimeout

(

uint64_t

timeout

)

Set Receive() timeout (in microseconds).
