UnixStream (UnixSocket &server, int size=512, bool throwflag=true, timeout_t timeout=0)

Create a Unix domain stream by accepting a connection from a bound Unix domain socket acting as a server. UnixStream (const char *pathname, int size=512, bool throwflag=true, timeout_t to=0)

Create a Unix domain stream by connecting to a Unix domain socket. void setTimeout (timeout_t to)

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

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

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

Flushes the stream input and output buffers, writes pending output. bool isPending (Pending pend, timeout_t timeout=TIMEOUT_INF)

Get the status of pending stream data. int getBufferSize (void) const

Return the size of the current stream buffering used.

UnixStream (bool throwflag=true)

The constructor required for 'unixstream', a more C++ style version of the TCPStream class. void allocate (int 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. virtual int underflow (void)

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

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

This streambuf method is used to write the output buffer through the established unix domain connection. void connect (const char *pathname, int size)

Create a Unix domain stream by connecting to a Unix domain socket. std::iostream * unixstr (void)

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

timeout_t timeout

int bufsize

char * gbuf

char * pbuf

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

Create a Unix domain stream by accepting a connection from a bound Unix domain 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 Unix domain stream by connecting to a Unix domain socket.

Parameters: pathname path to socket

size of streaming input and output buffers.

throwflag flag to throw errors.

to 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.

Create a Unix domain stream by connecting to a Unix domain socket.

Parameters: pathname path to socket

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.

Return the size of the current stream buffering used.

Returns: size of stream buffers.

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.

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

Parameters: ch char to push through.

Returns: char pushed through.

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

Parameters: to timeout to set.

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

Returns: 0 on success.

This streambuf method is used for doing unbuffered reads through the established unix domain socket connection when in interactive mode.

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

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

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

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

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.
