sctp_send - Send a message from a SCTP socket.
int sctp_send(int sd, const void * msg, size_t len,
const struct sctp_sndrcvinfo *sinfo,
sctp_send is a wrapper library function that can be used to send a
message from a socket without the use of the CMSG header structures. sd
is the socket descriptor from which the message pointed to by msg of
