Detailed Description

TCP/IP Networking API.

The TCP API manages the sending/receiving of data over TCP sockets.

First, establish a connection with TCP_Connect(), which will return a file descriptior. If TCP_Connect returns a value below 0, no connection is possible. You can send data through TCP_Send() once TCP_GetState returns STATE_CONNECTED.

You need to run TCP_Frame() on your tcpinfo_t struct every frame in order to listen to network activity.

#define TCP_BUFFER_LENGTH   32

Enumeration Type Documentation

tcpstate_t

enum tcpstate_t

State of a TCP connection.

Enumerator
STATE_DISCONNECTED	We're disconnected/unconnected.
STATE_CONNECTING	We're in the process of connecting.
STATE_CONNECTED	We're fully connected.

Function Documentation

TCP_Connect()

int TCP_Connect	(	tcpinfo_t *	in,
		string	path
	)

Open a TCP socket connection.

Parameters

in	Pointer to a tcpinfo_t struct to save state into.
path	The address:port to which we should connect to.

Returns

The descriptor for the newly opened socket. Will be below 0 if invalid.

TCP_Disconnect()

void TCP_Disconnect

(

tcpinfo_t *

in

)

Closes a TCP socket connection.

@parm in Pointer to a tcpinfo_t that is to be closed.

TCP_Frame()

void TCP_Frame

(

tcpinfo_t *

in

)

You want to run this every frame.

Parameters

in	Pointer to an active TCP connection.

TCP_GetState()

tcpstate_t TCP_GetState

(

tcpinfo_t *

in

)

Returns the tcpstate_t of a connection.

Parameters

in	Pointer to an active TCP connection.

TCP_Receive()

string TCP_Receive

(

tcpinfo_t *

in

)

Receive the latest message from a TCP connection.

Parameters

in	Pointer to an active TCP connection.

TCP_Send()

int TCP_Send	(	tcpinfo_t *	in,
		string	msg
	)

Send a string buffer to a specified TCP connection.

Parameters

in	Pointer to an active TCP connection.
msg	The message to send to the TCP connection.
