sctp_getladdrs Function
The sctp_getladdrs function can be used
to retrieve the local addresses that are part of an association.
This function is often necessary when a local endpoint wishes to
know exactly which local addresses are in use (which may be a
proper subset of the system's addresses).
|
#include <netinet/sctp.h>
|
|
int sctp_getladdrs(int sockfd, sctp_assoc_t id, struct sockaddr **addrs);
|
|
Returns: the number of local addresses stored in
addrs, 鈥? on error
|
The sockfd is
the socket descriptor returned by the socket function.
id is the association
identification for a one-to-many-style socket. If the socket is
using the one-to-one style, the id
field is ignored. The addrs
parameter is an address of a pointer that sctp_getladdrs
will fill in with a locally allocated, packed list of addresses.
See Figures 9.4 and
23.12 for details on
the structure of this return value. The caller should use
sctp_freeladdrs to free resources allocated by
sctp_getladdrs when finished with them.
