Cpl::Io::Stdio::StdErr Class Reference

This concrete class represents the C-library 'stderr' stream. More...

Detailed Description

This concrete class represents the C-library 'stderr' stream.

NOTE: Many instances of this class may be created - even though there is only ONE stderr. This is OK because all instance reference the systems/platform 'stderr'

Public Member Functions
	StdErr ()
	Constructor.
void	close ()
	Overriding inherited behavior so as to NOT close the actual native stream.
Public Member Functions inherited from Cpl::Io::Stdio::Output_
	Output_ (int fd)
	Constructor.
	Output_ (void *handle)
	Constructor.
	Output_ (Cpl::Io::Descriptor streamfd)
	Constructor.
	Output_ (void)
	Constructor.
	~Output_ (void)
	Destructor.
void	activate (int fd)
	Activates and/or resets the underlying 'fd' for the stream.
void	activate (void *handle)
	Activates and/or resets the underlying 'handle' for the stream.
void	activate (Cpl::Io::Descriptor streamfd)
	Activates and/or resets the underlying 'streamfd' for the stream.
bool	isOpened ()
	This method returns true if the file was successfully open and/or is still opened (i.e.
bool	write (const void *buffer, int maxBytes, int &bytesWritten)
	See Cpl::Io::Output.
void	flush ()
	See Cpl::Io::Output.
bool	isEos ()
	See Cpl::Io::IsEos.
Public Member Functions inherited from Cpl::Io::Output
virtual bool	write (char c)
	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.
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.

Additional Inherited Members
Static Public Member Functions inherited from Cpl::Container::Item
static void	remove_ (Item *itemPtr) noexcept
	Helper method to do the proper 'clean-up' for the multiple-containers-error-trap when removing an item from a container.
Public Attributes inherited from Cpl::Container::Item
void *	m_nextPtr_
	The link field.
void *	m_inListPtr_
	Debug field.
Protected Member Functions inherited from Cpl::Container::Item
	Item ()
	Constructor.
	Item (const char *)
	Constructor used ONLY with the child class MapItem: -->special constructor to allow a Map to be statically allocated.
Protected Attributes inherited from Cpl::Io::Stdio::Output_
Cpl::Io::Descriptor	m_outFd
	Stream Handle.
bool	m_outEos
	Cache end-of-stream status.

Constructor & Destructor Documentation

StdErr()

Cpl::Io::Stdio::StdErr::StdErr

(

)

Constructor.

Member Function Documentation

close()

void Cpl::Io::Stdio::StdErr::close ( )

virtual

Overriding inherited behavior so as to NOT close the actual native stream.

In general closing stdin/stdout/stderr is bad thing.

Reimplemented from Cpl::Io::Stdio::Output_.
