1 /* SCTP kernel Implementation
2 * Copyright (c) 2003 Hewlett-Packard Development Company, L.P

4 *
5 * This file has test cases to test the getsockopt () and sectsockopt () with
6 * SCTP_RTOINFO option on 1-1 style socket
7 *
8 * This program first gets the default values using getsockopt(). It also sets
9 * the value using setsockopt() and gets the set value using getsockopt().
10 * A comparison between set values and get values are performed.
