SCTP_GETPADDRS 3SOCKET "Jan 23, 2008"
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 allocated 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.
