-- Lists the instance profiles that have the specified associated IAM role. If there are none, the operation returns an empty list. For more information about instance profiles, go to <http://docs.aws.amazon.com/IAM/latest/UserGuide/AboutInstanceProfiles.html About Instance Profiles> .

-- You can paginate the results using the @MaxItems@ and @Marker@ parameters.

-- This operation returns paginated results.

-- | Creates a value of 'ListInstanceProfilesForRole' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'lipfrMarker' - 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.
--
-- * 'lipfrMaxItems' - (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.
--
-- * 'lipfrRoleName' - The name of the role to list instance profiles 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: _+=,.@-
