SCTP 协议实现源代码

/* SCTP kernel Implementation

 * (C) Copyright IBM Corp. 2004
 *
 * This file has test cases to test the getsockopt () and sectsockopt () with
 * SCTP_RTOINFO option on 1-1 style socket
 *
 * This program first gets the default values using getsockopt(). It also sets
 * the value using setsockopt() and gets the set value using getsockopt().
 * A comparison between set values and get values are performed.
