I can't think of a specific example, but I think you would probably
want to call the dynamically linked function from the .m file with

  args = varargin(first_parameter_arg:end);
  dynamically_linked_function (..., args{:});

or similar so that the dynamically linked function just sees a normal
argument list in an octave_value_list object..

Does that help?
