Описание (Description)
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.
SCTP_UNORDERED
This flags requests the un-ordered delivery of the
message.
SCTP_ADDR_OVER
This flag, in the one-to-many style, requests the SCTP
stack to override the primary destination address with
address specified in to.
SCTP_ABORT
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.
SCTP_EOF
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.
Возвращаемое значение (Return value)
On success, sctp_sendmsg returns the number of bytes sent or -1
if an error occurred.
