Public Member Functions inherited from Cpl::Io::Input
virtual bool	read (char &c)
	Reads a single byte from the stream.
virtual bool	read (Cpl::Text::String &destString)
	Reads N bytes into the String's internal buffer.
virtual	~Input ()
	Lets the make the destructor virtual.
Public Member Functions inherited from Cpl::Io::Close
virtual	~Close ()
	Lets the make the destructor virtual.
Public Member Functions inherited from Cpl::Container::Item
bool	insert_ (void *newContainerPtr)
	Helper method to trap when inserting an item in multiple containers.
bool	isInContainer_ (const void *containerPtr) const noexcept
	Returns 'true' if the instance is in the specified container.
Public Member Functions inherited from Cpl::Io::IsEos
virtual	~IsEos ()
	Lets the make the destructor virtual.
Public Member Functions inherited from Cpl::Io::Output

	Writes a single byte to the stream.
virtual bool	write (const char *string)
	Writes a string to the stream.
virtual bool	write (const Cpl::Text::String &string)
	Writes a string to the stream.
virtual bool	write (Cpl::Text::String &formatBuffer, const char *format,...)
	Formatted write to the stream.
virtual bool	vwrite (Cpl::Text::String &formatBuffer, const char *format, va_list ap)
	Same as write( String& formatBuffer, const char* format,...), except that it is called with a va_list instead of a variable number of arguments.
virtual bool	write (const void *buffer, int numBytes)
	Writes the content of the buffer to the stream.
virtual	~Output ()
	Lets the make the destructor virtual.

Constructor & Destructor Documentation

InputOutput() [1/2]

Cpl::Io::Socket::InputOutput::InputOutput

(

)

Constructor.

No 'fd' provided -->the instance MUST be activated prior to use.

InputOutput() [2/2]

Cpl::Io::Socket::InputOutput::InputOutput

(

Cpl::Io::Descriptor

fd

)

Constructor.

'fd' is a the 'socket descriptor' of a existing/opened socket

~InputOutput()

Cpl::Io::Socket::InputOutput::~InputOutput

(

void

)

Destructor.

Member Function Documentation

activate()

void Cpl::Io::Socket::InputOutput::activate

(

Cpl::Io::Descriptor

fd

)

Activates the stream, i.e.

initializes the instance's underlying fd/stream descriptor. If instance's 'fd' is not in the closed state when this method is called a fatal error is generated.

available()

virtual

See Cpl::Io::Input.

Implements Cpl::Io::Input.

close()

void Cpl::Io::Socket::InputOutput::close ( )

virtual

See Cpl::Io::Output.

Implements Cpl::Io::Close.

flush()

void Cpl::Io::Socket::InputOutput::flush ( )

virtual

See Cpl::Io::Output.
