44.Sh SYNOPSIS
45.In sys/types.h
46.In sys/socket.h
47.In sys/sctp.h
48.Ft int
49.Fn sctp_getpaddrs "int s" "sctp_assoc_t asocid" "struct sockaddr **addrs"
50.Ft int
51.Fn sctp_getladdrs "int s" "sctp_assoc_t asocid" "struct sockaddr **addrs"
52.Sh DESCRIPTION
53The
54.Fn sctp_getpaddrs
55function is used to get the list of the peers addresses.
56The
57.Fn sctp_getladdrs
58function is used to get the list of the local addresses.
59The association of interest is identified by the
60.Fa asocid
61argument. The addresses are returned in a newly allocated
62array of socket addresses returned in the argument
63.Fa addrs
64upon success.
65 .Pp
66After the caller is through the function
67.Fn sctp_freepaddrs
68or
69.Fn sctp_freeladdrs
70should be used to release the memory allocated by these

72.Sh RETURN VALUES
73The call returns -1 upon failure and a count of
74the number of addresses returned in
75.Fa addrs
76upon success.
77.Sh ERRORS
