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.

| 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.

| void ecl::OConsole::flush | ( | ) |
Flush the internal buffer.
Flushes the userspace buffers to standard output.
| StandardException | : throws if flushing returned an error [debug mode only]. |
Definition at line 49 of file console.cpp.
| 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.
Definition at line 61 of file console.hpp.
| 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.
| c | : the character to write. |
| StandardException | : throws if writing returned an error [debug mode only]. |
Definition at line 28 of file console.cpp.
| 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.
| s | : points to the beginning of the character string |
| n | : the number of characters to write. |
| StandardException | : throws if flushing returned an error [debug mode only]. |
