# stderr top-level property

Stdout stderr

The standard output stream of errors written by this program.

The `addError` API is inherited from `StreamSink` and calling it will result in an unhandled asynchronous error unless there is an error handler on `done`.

## Implementation

    Stdout get stderr {
      if (_stderr == null) {
        _stderr = _StdIOUtils._getStdioOutputStream(_stderrFD);
      }
      return _stderr;
    }
