34.Os
35.Sh NAME
36.Nm sctp_getpaddrs ,
37.Nm sctp_getladdrs
38.Nd return a list of addresses to the caller
39.Sh LIBRARY

41.Sh SYNOPSIS
42.In sys/types.h
43.In sys/socket.h
44.In netinet/sctp.h
45.Ft int
46.Fn sctp_getpaddrs "int s" "sctp_assoc_t asocid" "struct sockaddr **addrs"
47.Ft int
48.Fn sctp_getladdrs "int s" "sctp_assoc_t asocid" "struct sockaddr **addrs"
49.Sh DESCRIPTION
50The
51.Fn sctp_getpaddrs
52function is used to get the list of the peers addresses.
53The
54.Fn sctp_getladdrs
55function is used to get the list of the local addresses.
56The association of interest is identified by the
57.Fa asocid
58argument.
59The addresses are returned in a newly allocated
60array of socket addresses returned in the argument
61.Fa addrs
62upon success.
63.Pp
64After the caller is finished, the function
65.Xr sctp_freepaddrs 3
66or
67.Xr sctp_freeladdrs 3
68should be used to release the memory allocated by these
69calls.
70.Sh RETURN VALUES
71The call returns \-1 upon failure and a count of
72the number of addresses returned in
73.Fa addrs
74upon success.
75.Sh ERRORS
76The functions can return the following errors:
77.Bl -tag -width Er
78.It Bq Er EBADF
79The argument
80.Fa s
81is not a valid descriptor.
82.It Bq Er EINVAL
83An address listed has an invalid family or no
84addresses were provided.
85.It Bq Er ENOMEM
86The call cannot allocate memory to hold the
87socket addresses.
88.It Bq Er ENOTSOCK
89The argument
90.Fa s
91is not a socket.
