Member Function Documentation

const Error& ecl::EConsole::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 180 of file console.hpp.

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 81 of file console.cpp.

bool ecl::EConsole::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 139 of file console.hpp.

long ecl::EConsole::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 60 of file console.cpp.

long ecl::EConsole::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].
