    This function parses the function args and kwargs to obtain the

    This func is usually called from within a decorator.

    Note:

        This function currently does not work with functions that contain
        variable length args or kwargs arguments.

    Args:

        func (function): The function to examine (usually the function that is
            wrapped).

        argnames (iterable): An iterable sequence of argument names.

        *args: The positional arguments.

        **kwargs: The keyword arguments.

    Returns:

        :obj:`dict`: A mapping of argument name to argument value.
