sctp_getpaddrs - Returns all peer addresses in an association.

sctp_getpaddrs returns all peer addresses in an association. On return, addrs will point to a dynamically
       allocated packed array of sockaddr structures of the appropriate type for each address. The caller should
       use sctp_freepaddrs 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.

       sctp_freepaddrs frees all the resources allocated by sctp_getpaddrs.

       sctp_getpaddrs - Returns all peer addresses in an association.

       On success, sctp_getpaddrs returns the number of peer addresses  in  the  association.  If  there  is  no
       association  on this socket, 0 is returned and the value of *addrs is undefined. On error, sctp_getpaddrs
       returns -1 and the value of *addrs is undefined.
