NAME

6       sctp_getladdrs - Returns all locally bound addresses on a socket.

SYNOPSIS

9       #include <sys/types.h>
10       #include <sys/socket.h>
11       #include <netinet/sctp.h>
12
13       int sctp_getladdrs(int sd, sctp_assoc_t assoc_id,
14                          struct sockaddr **addrs);
15
16       void sctp_freeladdrs(struct sockaddr *addrs);

DESCRIPTION

19       sctp_getladdrs  returns  all  locally  bound  addresses on a socket. On
20       return, addrs will point to a dynamically  allocated  packed  array  of
21       sockaddr structures of the appropriate type for each local address. The
22       caller should use sctp_freeladdrs to free the  memory.  Note  that  the
23       in/out parameter addrs must not be NULL.
24
25       If  sd  is  an  IPv4  socket,  the  addresses returned will be all IPv4
26       addresses. If sd is an IPv6 socket, the addresses returned can be a mix
27       of IPv4 or IPv6 addresses.
28
29       For  one-to-many  style sockets, id specifies the association to query.
30       For one-to-one style sockets, id is ignored.
31
32       If the id field is set to 0,  then  the  locally  bound  addresses  are
33       returned without regard to any particular association.
34
35       sctp_freeladdrs frees all the resources allocated by sctp_getladdrs
36

RETURN VALUE

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