closeStdin method

@override Future<void> closeStdin()

Signals end-of-input on standard input (half-close).

Implementation

@override
Future<void> closeStdin() async {
  // A PTY has no half-close; deliver the terminal EOF character (Ctrl-D) so
  // the line discipline signals end-of-input to the foreground program.
  try {
    _process.stdin.add(const [0x04]);
  } on Object {
    // Ignore: child already gone.
  }
}
