      A ``None`` value indicates that the process has not terminated yet.

      A negative value ``-N`` indicates that the child was terminated
      by signal ``N`` (POSIX only).
      For processes created with :func:`~asyncio.create_subprocess_exec`, a negative
      value ``-N`` indicates that the child was terminated by signal ``N``
      (POSIX only).

      For processes created with :func:`~asyncio.create_subprocess_shell`, the
      return code reflects the exit status of the shell itself (e.g. ``/bin/sh``),
      which may map signals to codes such as ``128+N``. See the
      documentation of the shell (for example, the Bash manual's Exit Status)
      for details.
