NAME:        udpServerSctp 
SYNOPSIS:    udpServerSctp 
DESCRIPTION:    The program creates a datagram socket in the inet 
                domain and using SEQPACKET of SCTP protocol, 
                binds it to port 10111 and receives any message
                arrived to the socket and prints it out
