.B SCTP_EOF

Setting this flag invokes the SCTP graceful shutdown procedure on the specific

+.B SCTP_SENDALL
|
||
|
|
+This flag, if set, will cause a one-to-many style socket to send the message
|
||
|
|
+to all associations that are currently established on this socket. For the
|
||
|
|
+one-to-one style socket, this flag has no effect.

+.TP
|

|
+.B SCTP_SACK_IMMEDIATELY
|
||
|
|
+This flag allows the application to set the I bit of the last DATA chunk when
|
||
|
|
+sending each user message to make sure the corresponding SACK can be sent by
|
||
|
|
+peer without delay.

+.B SCTP_PR_SCTP_{TTL|RTX|PRIO}
|
||
|
|
+One of these 3 pr_policies can be used through this flag with its pr_value
|
||
|
|
+set in timetolive parameter for this message. Note that
|

|
|
+.B sctp_sendv(3)
