28 The \fBsctp_getpaddrs()\fR queries the peer addresses in an SCTP association.
29 The \fBsctp_freepaddrs()\fR function releases resources that are allocated to
33 The \fBsctp_getpaddrs()\fR function returns all the peer addresses in the SCTP
34 association identified by \fIsock\fR. On completion \fIaddrs\fR points to a
35 dynamically allocated array of \fBsockaddr_in\fR structures for an Internet
36 Protocol (IPv4) socket or an array of \fBsockaddr_in6\fR structures for an
37 Internet Protocol Version 6 (IPv6) socket. The \fIaddrs\fR parameter must not
38 be \fINULL\fR. For an IPv4 SCTP socket, the addresses returned in the
39 \fBsockaddr_in\fR structures are IPv4 addresses. For an IPv6 SCTP socket, the
40 addresses in the \fBsockaddr_in6\fR structures can be IPv6 addresses or
41 IPv4-mapped IPv6 addresses.
44 If \fIsock\fR is a one-to-many style SCTP socket, \fIid\fR specifies the
45 association of interest. If \fIsock\fR is a one-to-one style SCTP socket,
49 The \fBsctp_freepaddrs()\fR function frees the resources allocated by
50 \fBsctp_getpaddrs()\fR. The \fIaddrs\fR parameter is the array of addresses
51 allocated by \fBsctp_getpaddrs()\fR.
54 Upon successful completion, the \fBsctp_getpaddrs()\fR function returns the
55 number of addresses in the \fIaddrs\fR array. Otherwise, the function returns
56 \fB-1\fR and sets \fBerrno\fR to indicate the error.
59 The \fBsctp_getpaddrs()\fR succeeds unless one of the following conditions
67 The \fIsock\fR argument is an invalid file descriptor.
76 The \fIsock\fR argument is not a socket.
85 The \fIaddrs\fR argument is \fINULL\fR.
94 The \fIid\fR argument is an invalid association identifier for a one-to-many
