Detailed Description

Device for reading from standard output.

Device for reading from 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.

One peculiarity of this device, is that it will strip newlines from the incoming input. This is a characteristic exclusive to the input console device because of its interactive nature with the user.

Member Function Documentation

error()

const Error& ecl::IConsole::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 266 of file console.hpp.

open()

bool ecl::IConsole::open ( )

inline

Dummy handle to satisfy the input device concept.

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

Returns

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

Definition at line 229 of file console.hpp.

read() [1/2]

long ecl::IConsole::read

(

char &

c

Reads a single character from standard input.

Parameters

c	: character to read into from standard input.

Exceptions

StandardException

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

read() [2/2]

long ecl::IConsole::read	(	char *	s,
		const unsigned long &	n
	)

Reads a character string from standard input.

Reads a character string from standard input.
