47 call attempts to initiate an association to a peer SCTP
49 The call operates similarly to
51 but it also provides the ability to specify multiple destination
52 addresses for the peer.
53 This allows a fault tolerant method
54 of initiating an association.
55 When one of the peers addresses
56 is unreachable, the subsequent listed addresses will also be used
57 to set up the association with the peer.
59 The user also needs to consider that any address listed in an
61 call is also considered "confirmed".
62 A confirmed address is one in
63 which the SCTP transport will trust is a part of the association
64 and it will not send a confirmation heartbeat to it with
67 If the peer SCTP stack does not list one or more of
68 the provided addresses in its response message then
69 the extra addresses sent in the
71 call will be silently discarded from the association.
