19 sctp_getladdrs returns all locally bound addresses on a socket. On
20 return, addrs will point to a dynamically allocated packed array of
21 sockaddr structures of the appropriate type for each local address. The
22 caller should use sctp_freeladdrs to free the memory. Note that the
23 in/out parameter addrs must not be NULL.
24
25 If sd is an IPv4 socket, the addresses returned will be all IPv4
26 addresses. If sd is an IPv6 socket, the addresses returned can be a mix
27 of IPv4 or IPv6 addresses.
28
29 For one-to-many style sockets, id specifies the association to query.
30 For one-to-one style sockets, id is ignored.
31
32 If the id field is set to 0, then the locally bound addresses are
33 returned without regard to any particular association.
34
35 sctp_freeladdrs frees all the resources allocated by sctp_getladdrs
36
38 On success, sctp_getladdrs returns the number of local addresses bound
39 to the socket. If the socket is unbound, 0 is returned and the value of
40 *addrs is undefined. On error, sctp_getladdrs returns -1 and the value
41 of *addrs is undefined.
