void flush (void)

Forces any buffered data to be transmitted to the TCP server, regardless of the size of the content.

Parameters: None

Returns: Nothing

Callback API

To make working with TCP sockets easier, a simple callback API is available in AdafruitTCP based on the following

functions:

void setReceivedCallback (tcpcallback_t fp)

Registers the data received callback handler.

Parameters:

fp: The name of the function that will be executed when received data is available from the TCP server. See the

example below for details on the function signature.

Returns: Nothing

void setDisconnectCallback (tcpcallback_t fp)

Registers the disconnect callback handler (fired when you are disconnected from the TCP server).

Parameters:

fp: The name of the function that will be executed when you are disconnected from the TCP server. See the

example below for details on the function signature.

Returns: Nothing

Callback Function Signatures

The data received and disconnect callbacks both require a specific function definition to work. The function names

('receive_callback' and 'disconnect_callback') can change, but the exact signatures are shown below:

You then register the callbacks with the dedicated set callback functions:

void receive_callback ( void );

void disconnect_callback ( void );

Make sure you register the callbacks BEFORE calling the .connect function!
