It should be 'snp->sn_header.sn_type', not 'snp->sn_types'.

See the socket API: http://tools.ietf.org/html/draft-ietf-tsvwg-sctpsocket-27

Section 6.1.  SCTP Notification Structure

   union sctp_notification {
     struct sctp_tlv {
       uint16_t sn_type; /* Notification type. */
       uint16_t sn_flags;
       uint32_t sn_length;
     } sn_header;
     struct sctp_assoc_change sn_assoc_change;
     struct sctp_paddr_change sn_paddr_change;
     struct sctp_remote_error sn_remote_error;
     struct sctp_send_failed sn_send_failed;
     struct sctp_shutdown_event sn_shutdown_event;
     struct sctp_adaptation_event sn_adaptation_event;
     struct sctp_pdapi_event sn_pdapi_event;
     struct sctp_authkey_event sn_auth_event;
     struct sctp_sender_dry_event sn_sender_dry_event;
     struct sctp_send_failed_event sn_send_failed_event;
   };
