-- Lists the names of the inline policies embedded in the specified IAM user.
--
--
-- An IAM user can also have managed policies attached to it. To list the managed policies that are attached to a user, use 'ListAttachedUserPolicies' . For more information about policies, see <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 user, the operation returns an empty list.
--
--
-- This operation returns paginated results.

-- | Creates a value of 'ListUserPolicies' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'lupMarker' - Use this parameter only when paginating results and only after you receive a response indicating that the results are truncated. Set it to the value of the @Marker@ element in the response that you received to indicate where the next call should start.
--
-- * 'lupMaxItems' - (Optional) Use this only when paginating results to indicate the maximum number of items you want in the response. If additional items exist beyond the maximum you specify, the @IsTruncated@ response element is @true@ . If you do not include this parameter, it defaults to 100. Note that IAM might return fewer results, even when there are more results available. In that case, the @IsTruncated@ response element returns @true@ and @Marker@ contains a value to include in the subsequent call that tells the service where to continue from.
--
-- * 'lupUserName' - The name of the user to list policies for. This parameter allows (per its <http://wikipedia.org/wiki/regex regex pattern> ) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-
