37.Os
38.Sh NAME
39.Nm sctp_getpaddrs ,
40.Nm sctp_getladdrs
41.Nd return a list of addresses to the caller
42.Sh LIBRARY
43.Lb libc
44.Sh SYNOPSIS
45.In sys/types.h
46.In sys/socket.h
47.In netinet/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.
62The addresses are returned in a newly allocated
63array of socket addresses returned in the argument
64.Fa addrs
65upon success.
66.Pp
67After the caller is finished, the function
68.Fn sctp_freepaddrs
69or
70.Fn sctp_freeladdrs
71should be used to release the memory allocated by these
72calls.
73.Sh RETURN VALUES
74The call returns -1 upon failure and a count of
75the number of addresses returned in
76.Fa addrs
77upon success.
78.Sh ERRORS
79The functions can return the following errors:
80.Bl -tag -width Er
81.It Bq Er EINVAL
82An address listed has an invalid family or no
83addresses were provided.
84.It Bq Er ENOMEM
85The call cannot allocate memory to hold the
86socket addresses.
87.It Bq Er EBADF
88The argument
89.Fa s
90is not a valid descriptor.
91.It Bq Er ENOTSOCK
92The argument
93.Fa s
94is not a socket.
