SCTP_GETPADDRS(3)          Linux Programmer's Manual         SCTP_GETPADDRS(3)

       sctp_getpaddrs - Returns all peer addresses in an association.

       #include <sys/types.h>
       #include <sys/socket.h>
       #include <netinet/sctp.h>

       int sctp_getpaddrs(int sd, sctp_assoc_t assoc_id,
                          struct sockaddr **addrs);

       void sctp_freepaddrs(struct sockaddr *addrs);

       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.

       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.
