      ----------
      connection_file : str [optional]
          The connection file to be used. Can be given by absolute path, or
          IPython will search in the security directory of a given profile.
          If run from IPython,
  
          If unspecified, the connection file for the currently running
          IPython Kernel will be used, which is only allowed from inside a kernel.
      unpack : bool [default: False]
          if True, return the unpacked dict, otherwise just the string contents
          of the file.

      Returns
      -------
      The connection dictionary of the current kernel, as string or dict,
