33.Os
34.Sh NAME
35.Nm sctp_getpaddrs ,
36.Nm sctp_getladdrs
37.Nd return a list of addresses to the caller
38.Sh LIBRARY
39.Lb libc
40.Sh SYNOPSIS
41.In sys/types.h
42.In sys/socket.h
43.In netinet/sctp.h
44.Ft int
45.Fn sctp_getpaddrs "int s" "sctp_assoc_t asocid" "struct sockaddr **addrs"
46.Ft int
47.Fn sctp_getladdrs "int s" "sctp_assoc_t asocid" "struct sockaddr **addrs"
48.Sh DESCRIPTION
49The
50.Fn sctp_getpaddrs
51function is used to get the list of the peers addresses.
52The
53.Fn sctp_getladdrs
54function is used to get the list of the local addresses.
55The association of interest is identified by the
56.Fa asocid
57argument.
58The addresses are returned in a newly allocated
59array of socket addresses returned in the argument
60.Fa addrs
61upon success.
62.Pp
63After the caller is finished, the function
64.Fn sctp_freepaddrs
65or
66.Fn sctp_freeladdrs
67should be used to release the memory allocated by these
68calls.
69.Sh RETURN VALUES
70The call returns -1 upon failure and a count of
71the number of addresses returned in
72.Fa addrs
73upon success.
74.Sh ERRORS
75The functions can return the following errors:
76.Bl -tag -width Er
77.It Bq Er EINVAL
78An address listed has an invalid family or no
79addresses were provided.
80.It Bq Er ENOMEM
81The call cannot allocate memory to hold the
82socket addresses.
83.It Bq Er EBADF
84The argument
85.Fa s
86is not a valid descriptor.
87.It Bq Er ENOTSOCK
88The argument
89.Fa s
90is not a socket.
