NAME
sctp_getpaddrs - Returns all peer addresses in an association.
SYNOPSIS
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/sctp.h>
int sctp_getpaddrs(int sd, sctp_assoc_t assoc_id,
struct sockaddr **addrs);
void sctp_freepaddrs(struct sockaddr *addrs);
DESCRIPTION
sctp_getpaddrs returns all peer addresses in an association. On return,
addrs will point to a dynamically allocated packed array of sockaddr
structures of the appropriate type for each address. The caller should
use sctp_freepaddrs to free the memory. Note that the in/out parameter
addrs must not be NULL.
If sd is an IPv4 socket, the addresses returned will be all IPv4
addresses. If sd is an IPv6 socket, the addresses returned can be a mix
of IPv4 or IPv6 addresses.
For one-to-many style sockets, id specifies the association to query.
For one-to-one style sockets, id is ignored.
sctp_freepaddrs frees all the resources allocated by sctp_getpaddrs.
RETURN VALUE
On success, sctp_getpaddrs returns the number of peer addresses in the
association. If there is no association on this socket, 0 is returned
and the value of *addrs is undefined. On error, sctp_getpaddrs returns
-1 and the value of *addrs is undefined.
