Detailed Description

This class implements the OutputStream interface for writing bytes to the standard output stream stdout.

Example: StdoutOutputStream basic usage: StdoutOutputStream stdos();

stdos.write(<01>);

stdos.write(<0203>);

# three bytes have been written to stdout: 01 02 03

Note: stream classes are not designed to be accessed from multiple threads; they have been implemented without locking for fast and efficient use when used from a single thread. For methods that would be unsafe to use in another thread, any use of such methods in threads other than the thread where the constructor was called will cause a STREAM-THREAD-ERROR to be thrown, unless the stream is handed off to another thread using the StreamBase::unassignThread() method in the thread that currently owns the stream, and the StreamBase::reassignThread() method in the new thread.
