sctp_peeloff(3SOCKET) Sockets Library Functions sctp_peeloff(3SOCKET)NAME
sctp_peeloff - branch off existing association from a one-to-many SCTP socket to create a one-to-one STP socket
SYNOPSIS
cc [ flag... ] file... -lsocket -lnsl -lsctp [ library... ]
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/sctp.h>
int sctp_peeloff(int sock, sctp_assoc_t id);
DESCRIPTION
The sctp_peeloff() function branches off an existing association from a one-to-many style SCTP socket into a separate socket file descrip-
tor. The resulting branched-off socket is a one-to-one style SCTP socket and is confined to operations allowed on a one-to-one style SCTP
socket.
The sock argument is a one-to-many socket. The association specified by the id argument is branched off sock.
RETURN VALUES
Upon successful completion, the sctp_peeloff() function returns the file descriptor that references the branched-off socket. The function
returns -1 if an error occurs.
ERRORS
The sctp_peeloff() function fails under the following conditions.
EOPTNOTSUPP The sock argument is not a one-to-many style SCTP socket.
EINVAL The id is 0 or greater than the maximum number of associations for sock.
EMFILE Failure to create a new user file descriptor or file structure.

sctp_getpaddrs(3SOCKET) Sockets Library Functions sctp_getpaddrs(3SOCKET)NAME
sctp_getpaddrs, sctp_freepaddrs - returns all peer addresses on an SCTP association
SYNOPSIS
cc [ flag... ] file... -lsocket -lnsl -lsctp [ library... ]
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/sctp.h>
int sctp_getpaddrs(int sock, sctp_assoc_t id, void **addrs);
void sctp_freepaddrs(void *addrs);
DESCRIPTION
The sctp_getpaddrs() queries the peer addresses in an SCTP association. The sctp_freepaddrs() function releases resources that are allo-
cated to hold the addresses.
The sctp_getpaddrs() function returns all the peer addresses in the SCTP association identified by sock. On completion addrs points to a
dynamically allocated array of sockaddr_in structures for an Internet Protocol (IPv4) socket or an array of sockaddr_in6 structures for an
Internet Protocol Version 6 (IPv6) socket. The addrs parameter must not be NULL. For an IPv4 SCTP socket, the addresses returned in the
sockaddr_in structures are IPv4 addresses. For an IPv6 SCTP socket, the addresses in the sockaddr_in6 structures can be IPv6 addresses or
IPv4-mapped IPv6 addresses.
If sock is a one-to-many style SCTP socket, id specifies the association of interest. If sock is a one-to-one style SCTP socket, id is
ignored.
The sctp_freepaddrs() function frees the resources allocated by sctp_getpaddrs(). The addrs parameter is the array of addresses allocated
by sctp_getpaddrs().
RETURN VALUES
Upon successful completion, the sctp_getpaddrs() function returns the number of addresses in the addrs array. Otherwise, the function
returns -1 and sets errno to indicate the error.
ERRORS
The sctp_getpaddrs() succeeds unless one of the following conditions exist.
EBADF The sock argument is an invalid file descriptor.
ENOTSOCK The sock argument is not a socket.
EINVAL The addrs argument is NULL.
EINVAL The id argument is an invalid association identifier for a one-to-many style STP socket.
ENOTCONN The specified socket is not connected.
