-- Lists the root or organizational units (OUs) that serve as the immediate
-- parent of the specified child OU or account. This operation, along with
-- ListChildren enables you to traverse the tree structure that makes up
-- this root.
--
-- Always check the @NextToken@ response parameter for a @null@ value when
-- calling a @List*@ operation. These operations can occasionally return an
-- empty set of results even when there are more results available. The
-- @NextToken@ response parameter value is @null@ /only/ when there are no
-- more results to display.
--
-- This operation can be called only from the organization\'s management
-- account or by a member account that is a delegated administrator for an
-- Amazon Web Services service.
--
-- In the current release, a child can have only a single parent.
--
-- This operation returns paginated results.
