NAME         top

       sctp_getladdrs - Returns all locally bound addresses on a socket.

SYNOPSIS         top

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

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

       void sctp_freeladdrs(struct sockaddr *addrs);

DESCRIPTION         top

       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

RETURN VALUE         top

       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.
