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

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 sctp_getladdrs

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.
