Construct a named TCP Socket connected to a remote machine. void setTimeout (timeout_t to)

Set the I/O operation timeout for socket I/O operations. TCPStream (const TCPStream &source)

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

Flush and empty all buffers, and then remove the allocated buffers. int sync (void)

Flushes the stream input and output buffers, writes pending output. size_t printf (const char *format,...)

Print content into a socket. bool isPending (Pending pend, timeout_t timeout=TIMEOUT_INF)

Get the status of pending stream data. ssize_t peek (void *buf, size_t len)

Examine contents of next waiting packet. size_t getBufferSize (void) const

Return the size of the current stream buffering used.

void allocate (size_t size)

Used to allocate the buffer space needed for iostream operations. void endStream (void)

Used to terminate the buffer space and cleanup the socket connection. int underflow ()

This streambuf method is used to load the input buffer through the established tcp socket connection. int uflow ()

This streambuf method is used for doing unbuffered reads through the establish tcp socket connection when in interactive mode. int overflow (int ch)

This streambuf method is used to write the output buffer through the established tcp connection. void connect (const IPV4Host &host, tpport_t port, unsigned mss=536)

Create a TCP stream by connecting to a TCP socket (on a remote machine). void connect (const IPV6Host &host, tpport_t port, unsigned mss=536)

void connect (const char *service, unsigned mss=536)

TCPStream & crlf (TCPStream &)

TCPStream & lfcr (TCPStream &)

The constructor required for building other classes or to start an unconnected TCPStream for connect.

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

This performs an 'accept' call.

Parameters: server socket listening

size of streaming input and output buffers.

throwflag flag to throw errors.

timeout for all operations.

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.

throwflag flag to throw errors.

timeout for all operations.

Construct a named TCP Socket connected to a remote machine.

Parameters: name of remote service.

family of protocol.

size of streaming buffers.

throwflag flag to throw errors.

timeout for all operations.

A copy constructor creates a new stream buffer.

Parameters: source of copy.

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

Used to allocate the buffer space needed for iostream operations.

This function is called by the constructor.

Parameters: size of stream buffers from constructor.

Accept a connection from a TCP Server.

Parameters: server socket listening

Connect a TCP stream to a named destination host and port number, using getaddrinfo interface if available.

Parameters: name of host and service to connect

size of stream buffer

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.

Examples: tcp.cpp.

Disconnect the current session and prepare for a new one.

Examples: tcp.cpp, and tcpstr1.cpp.

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

This fucntion is called by the destructor.

Return the size of the current stream buffering used.

Returns: size of stream buffers.

Get protocol segment size.

Examples: tcp.cpp.

Get the status of pending stream data.

This 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 and if write buffer contains data it is first flushed and then checked.

Examples: tcp.cpp.

This streambuf method is used to write the output buffer through the established tcp connection.

Parameters: ch char to push through.

Returns: char pushed through.

Examine contents of next waiting packet.

Parameters: buf pointer to packet buffer for contents.

len of packet buffer.

Returns: number of bytes examined.

Print content into a socket.

Returns: count of bytes sent.

Parameters: format string

Set the I/O operation timeout for socket I/O operations.

Parameters: to timeout to set.

Reimplemented in ost::URLStream.

Flushes the stream input and output buffers, writes pending output.

Returns: 0 on success.

Used in derived classes to refer to the current object via it's iostream.

For example, to send a set of characters in a derived method, one might use *tcp() << 'test'.

Returns: stream pointer of this object.

This streambuf method is used for doing unbuffered reads through the establish tcp socket connection when in interactive mode.

Also this method will handle proper use of buffers if not in interative mode.

Returns: char from tcp socket connection, EOF if not connected.

This streambuf method is used to load the input buffer through the established tcp socket connection.

Returns: char from get buffer, EOF if not connected.
