sctp_sendmsg - Send a message from a SCTP socket.
int sctp_sendmsg(int sd, const void * msg, size_t len,
struct sockaddr *to, socklen_t tolen,
uint32_t ppid, uint32_t flags,
uint16_t stream_no, uint32_t timetolive,
sctp_sendmsg is a wrapper library function that can be used to send a
message from a socket while using the advanced features of SCTP. sd is
the socket descriptor from which the message pointed to by msg of
length len is sent. to is the destination address of the message and
tolen is the length of the destination address. stream_no identifies
the stream number that the application wishes to send this message to.
flags parameter is composed of a bitwise OR of the following values.
This flags requests the un-ordered delivery of the message.
This flag, in the one-to-many style, requests the SCTP stack to
override the primary destination address with address specified
Setting this flag causes the specified association to abort by
sending an ABORT message to the peer(one-to-many style only).
The ABORT chunk will contain an error cause ’User Initiated
Abort’ with cause code 12. The cause specific information of
this error cause is provided in msg.
Setting this flag invokes the SCTP graceful shutdown procedure
on the specific association(one-to-many style only).
timetolive specifies the time duration in milliseconds. The sending
side will expire the message if the message has not been sent to the
peer within this time period. A value of 0 indicates that no timeout
should occur on this message. ppid is an opaque unsigned value that is
passed to the remote end along with the message. context is a 32 bit
opaque value that is passed back to the upper layer along with the
undelivered message if an error occurs on the send of the message.
On success, sctp_sendmsg returns the number of bytes sent or -1 if an
