Detailed Description

Device for writing to standard output.

Device for writing to standard output. It creates a wrapper class around the stdout handle from cstdio to implement an ecl output device. Do not use this directly, it serves only as the device handle for the console stream classes.

Member Function Documentation

error()

const Error& ecl::OConsole::error ( ) const

inline

Returns the most recent error status.

Use this to check on the status of the object after a method has been called. Mostly this is here to serve as a graceful fallback for when exceptions are disabled.

Returns

Definition at line 117 of file console.hpp.

flush()

void ecl::OConsole::flush

(

)

Flush the internal buffer.

Flushes the userspace buffers to standard output.

Exceptions

StandardException

: throws if flushing returned an error [debug mode only].

Definition at line 53 of file console.cpp.

open()

bool ecl::OConsole::open ( )

inline

Dummy handle to satisfy the output device concept.

For console devices this does nothing - the standard output is always open. It is just a dummy handle built to ensure the output device concept is satisfied.

Returns

bool : always returns true (it is always open).

Definition at line 76 of file console.hpp.

write() [1/2]

long ecl::OConsole::write

(

const char &

c

)

Write a character to the buffer.

Write a character to the buffer. It will automatically flush if the buffer exceeds its capacity.

Parameters

c	: the character to write.

Returns

long : the number of bytes written.

Exceptions

StandardException

: throws if writing returned an error [debug mode only].

Definition at line 32 of file console.cpp.

write() [2/2]

long ecl::OConsole::write	(	const char *	s,
		unsigned long	n
	)

Write a character string to the buffer.

Write a character string to the buffer. It will automatically flush if the buffer exceeds its capacity.

Parameters

s	: points to the beginning of the character string
n	: the number of characters to write.

Returns

long: the number of bytes written.

Exceptions

StandardException

: throws if flushing returned an error [debug mode only].

Definition at line 41 of file console.cpp.
