{
    VALUE super;

    if (rb_typeddata_is_kind_of(obj, &iow_data_type)) {
        obj = (VALUE)DATA_PTR(obj);
    }

    switch (OBJ_BUILTIN_TYPE(obj)) {
      case T_MODULE:
      case T_CLASS:
      case T_ICLASS:
        super = rb_class_super_of(obj);
        break;
      default:
        rb_raise(rb_eArgError, "class or module is expected");
    }

    return wrap_klass_iow(super);
}

Returns the immediate superclass of cls, including any hidden class such as an included module’s iclass.

Unlike Class#superclass, this does not skip over the iclasses that Ruby inserts for included modules:

Example

require 'objspace'

module M; end
class A; include M; end
A.superclass                       # => Object
ObjectSpace.internal_super_of(A)   # => #<InternalObject:0x... T_ICLASS>

cls must be a Class or Module, or an ObjectSpace::InternalObjectWrapper that wraps one.

Note that you should not use this method in your application.

This method is only expected to work with C Ruby.
