Dear Mr.Tuexen,

Thank you very much for your reply.
Compile was OK but when I running the client program(receive
message),the "Create socket error!"was printed out.
This is my fully source code of CreateSocket():
int CreateSocket()
{
int in, tempSock, ret, ret_1;
struct sockaddr_in servaddr, servaddr_1;
struct sctp_status status;
//struct sctp_sndrcvinfo sndrcvinfo;
struct sctp_event_subscribe events;
struct sctp_initmsg initmsg;

/* Create an SCTP TCP-Style Socket */
connSock = socket(AF_INET, SOCK_STREAM, IPPROTO_SCTP);
connSock_1 = socket(AF_INET, SOCK_STREAM, IPPROTO_SCTP);
if (tempSock < 0 || connSock_1 < 0) {
printf("Create socket error!\n");
exit (-1);
}

/* Specify that a maximum of 5 streams will be available per socket */
memset(&initmsg, 0, sizeof(initmsg));
initmsg.sinit_num_ostreams = conf.thread;
initmsg.sinit_max_instreams = conf.thread;
initmsg.sinit_max_attempts = 1;
ret = setsockopt(connSock, IPPROTO_SCTP, SCTP_INITMSG,
&initmsg, sizeof(initmsg));
ret_1 = setsockopt(connSock_1, IPPROTO_SCTP, SCTP_INITMSG,
&initmsg, sizeof(initmsg));

/* Specify the peer endpoint to which we'll connect */
bzero((void *)&servaddr, sizeof(servaddr));
servaddr.sin_family = AF_INET;
servaddr.sin_port = htons(MY_PORT_NUM);
servaddr.sin_addr.s_addr = inet_addr(conf.ip);

/* Specify the peer endpoint to which we'll connect */
bzero((void *)&servaddr_1, sizeof(servaddr_1));
servaddr_1.sin_family = AF_INET;
servaddr_1.sin_port = htons(MY_PORT_NUM+1);
servaddr_1.sin_addr.s_addr = inet_addr(conf.ip);

/* Connect to the server */
ret = connect(connSock, (struct sockaddr *)&servaddr, sizeof(servaddr));
ret_1 = connect(connSock_1, (struct sockaddr *)&servaddr_1,
sizeof(servaddr_1));
if (ret == -1 || ret_1 == -1) {
perror("Connection failure: ");
exit (-1);
}

/* Enable receipt of SCTP Snd/Rcv Data via sctp_recvmsg */
memset( (void *)&events, 0, sizeof(events) );
events.sctp_data_io_event = 1;
ret = setsockopt( connSock, SOL_SCTP, SCTP_EVENTS,
(const void *)&events, sizeof(events) );

/* Read and emit the status of the Socket (optional step) */
in = sizeof(status);
ret = getsockopt( connSock, SOL_SCTP, SCTP_STATUS,
(void *)&status, (socklen_t *)&in );

printf("assoc id = %d\n", status.sstat_assoc_id );
printf("state = %d\n", status.sstat_state );
printf("instrms = %d\n", status.sstat_instrms );
printf("outstrms = %d\n", status.sstat_outstrms );

return connSock;
}

Best regards
