sctp_getladdrs - Returns all locally bound addresses on a socket.

sctp_getladdrs  returns  all  locally  bound  addresses  on  a  socket.  On return, addrs will point to a
       dynamically allocated packed array of sockaddr structures of the appropriate type for each local address.
       The caller should use sctp_freeladdrs to free the memory. Note that the in/out parameter addrs  must  not
       be NULL.

       If  sd is an IPv4 socket, the addresses returned will be all IPv4 addresses. If sd is an IPv6 socket, the
       addresses returned can be a mix of IPv4 or IPv6 addresses.

       For one-to-many style sockets, id specifies the association to query. For one-to-one style sockets, id is
       ignored.

       If the id field is set to 0, then the  locally  bound  addresses  are  returned  without  regard  to  any
       particular association.

       sctp_freeladdrs frees all the resources allocated by sctp_getladdrs

       sctp_getladdrs - Returns all locally bound addresses on a socket.

       On  success,  sctp_getladdrs  returns the number of local addresses bound to the socket. If the socket is
       unbound, 0 is returned and the value of *addrs is undefined. On error, sctp_getladdrs returns -1 and  the
       value of *addrs is undefined.
