-- Lists the names of the inline policies that are embedded in the specified role.
--
-- A role can also have managed policies attached to it. To list the managed policies that are attached to a role, use < ListAttachedRolePolicies>. For more information about policies, refer to <http://docs.aws.amazon.com/IAM/latest/UserGuide/policies-managed-vs-inline.html Managed Policies and Inline Policies> in the /IAM User Guide/.
--
-- You can paginate the results using the 'MaxItems' and 'Marker' parameters. If there are no inline policies embedded with the specified role, the action returns an empty list.
--
-- This operation returns paginated results.
