All of the global methods become singleton methods of
the top-level Object object, so you should be able to
refer to rb_cObject (I am unable to test). If that
does not work, see if README.EXT provides any clues.
They are private instance methods of Object.
$ ruby -e 'def foo;end; p Object.private_instance_methods.grep(/foo/)'
["foo"]
So the receiver is not a matter,
rb_funcall2(Qnil, rb_intern("test"), 0, NULL);
rb_funcall2(INT2FIX(999), rb_intern("test"), 0, NULL);
rb_funcall2(rb_cArray, rb_intern("test"), 0, NULL);
rb_funcall2(rb_str_new(0, 0), rb_intern("test"), 0, NULL);
rb_funcall2(rb_ary_new(), rb_intern("test"), 0, NULL);
rb_funcall2(rb_hash_new(), rb_intern("test"), 0, NULL);
rb_funcall2(rb_module_new(), rb_intern("test"), 0, NULL);
all work.
