SimpleTCPStream (TCPSocket &server, size_t size=512)

Create a TCP stream by accepting a connection from a bound TCP socket acting as a server. SimpleTCPStream (const IPV4Host &host, tpport_t port, size_t size=512)

Create a TCP stream by connecting to a TCP socket (on a remote machine). SimpleTCPStream (const SimpleTCPStream &source)

A copy constructor creates a new stream buffer. virtual ~SimpleTCPStream ()

Flush and empty all buffers, and then remove the allocated buffers. bool isPending (Pending pend, timeout_t timeout=TIMEOUT_INF)

Get the status of pending stream data. void flush ()

ssize_t read (char *bytes, size_t length, timeout_t timeout=0)

Read bytes into a buffer. ssize_t write (const char *bytes, size_t length, timeout_t timeout=0)

Write bytes to buffer. ssize_t peek (char *bytes, size_t length, timeout_t timeout=0)

Peek at the incoming data.

SimpleTCPStream ()

The constructor required for 'SimpleTCPStream', a more C++ style version of the SimpleTCPStream class. void endStream (void)

Used to terminate the buffer space and cleanup the socket connection. void Connect (const IPV4Host &host, tpport_t port, size_t size)

Create a TCP stream by connecting to a TCP socket (on a remote machine).

The constructor required for 'SimpleTCPStream', a more C++ style version of the SimpleTCPStream class.

Create a TCP stream by accepting a connection from a bound TCP socket acting as a server.

This performs an 'accept' call.

Parameters: server bound server tcp socket.

size of streaming input and output buffers.

Create a TCP stream by connecting to a TCP socket (on a remote machine).

Parameters: host address of remote TCP server.

port number to connect.

size of streaming input and output buffers.

A copy constructor creates a new stream buffer.

Parameters: source A reference to the SimpleTCPStream to copy.

Flush and empty all buffers, and then remove the allocated buffers.

Create a TCP stream by connecting to a TCP socket (on a remote machine).

Parameters: host address of remote TCP server.

port number to connect.

size of streaming input and output buffers.

Used to terminate the buffer space and cleanup the socket connection.

This fucntion is called by the destructor.

Get the status of pending stream data.

This method can be used to examine if input or output is waiting, or if an error or disconnect has occured on the stream. If a read buffer contains data then input is ready. If write buffer contains data, it is first flushed and then checked.

Parameters: pend Flag indicating means to pend.

timeout The length of time to wait.

Peek at the incoming data.

The data is copied into the buffer but is not removed from the input queue. The function then returns the number of bytes currently pending to receive.

Parameters: bytes A pointer to buffer that will contain the bytes read.

length The number of bytes to read (exactly).

timeout Period to time out, in milleseconds.

Returns: The number of bytes pending on the input queue, 0 on EOF.

Read bytes into a buffer.

<long-description>

Parameters: bytes A pointer to buffer that will contain the bytes read.

length The number of bytes to read (exactly).

timeout Period to time out, in milleseconds.

Returns: The number of bytes actually read, 0 on EOF.

Write bytes to buffer.

<long-description>

Parameters: bytes A pointer to a buffer containing the bytes to write.

length The number of bytes to write (exactly).

timeout Period to time out, in milleseconds.

Returns: The number of bytes actually written.
