     The variable must be either an equal-style (or equivalent)
     variable or an atom-style variable. The variable type can be
     provided as the ``vartype`` parameter, which may be one of several
-    constants: ``LMP_VAR_EQUAL``, ``LMP_VAR_ATOM``, or ``LMP_VAR_STRING``.
-    If omitted or ``None``, LAMMPS will determine its value for you based on
-    a call to :cpp:func:`lammps_extract_variable_datatype` from the C library
-    interface.  The group parameter is only used for atom-style variables and
-    defaults to the group "all".
