Detailed Description

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

Restrictions:
Qore::PO_NO_TERMINAL_IO
Example: StderrOutputStream basic usage
StderrOutputStream seos();
seos.write(<01>);
seos.write(<0203>);
# three bytes have been written to stderr: 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.
This class is not available with the PO_NO_TERMINAL_IO parse option
