TCP/IP Networking API. More...

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.

Function Documentation

◆ TCP_Connect()

int TCP_Connect ( tcpinfo_t in,
string  path 
)

Open a TCP socket connection.

Parameters
inPointer to a tcpinfo_t struct to save state into.
pathThe 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
inPointer to an active TCP connection.

◆ TCP_GetState()

tcpstate_t TCP_GetState ( tcpinfo_t in)

Returns the tcpstate_t of a connection.

Parameters
inPointer to an active TCP connection.

◆ TCP_Receive()

string TCP_Receive ( tcpinfo_t in)

Receive the latest message from a TCP connection.

Parameters
inPointer 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
inPointer to an active TCP connection.
msgThe message to send to the TCP connection.
