sctp_bindx - Add or remove bind addresses on a socket.
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/sctp.h>
int sctp_bindx(int sd, struct sockaddr * addrs, int addrcnt,
int flags);
sctp_bindx adds or removes a set of bind addresses passed in the array
addrs to/from the socket
sd. addrcnt is the number of
addresses in the array and the
flags paramater indicates if the
addresses need to be added or removed.
If
sd is an IPv4 socket, the addresses passed must be IPv4 addresses. If
sd is an IPv6 socket, the addresses passed can be either IPv4 or IPv6
addresses.
addrs is a pointer to an array of one or more socket addresses. Each
address is contained in its appropriate structure(i.e. struct sockaddr_in or
struct sockaddr_in6). The family of the address type must be used to
distinguish the address length. The caller specifies the number of addresses
in the array with
addrcnt.
The
flags parameter can be either
SCTP_BINDX_ADD_ADDR or
SCTP_BINDX_REM_ADDR. An application can use
SCTP_BINDX_ADD_ADDR
to associate additional addresses with an endpoint after calling
bind(2).
SCTP_BINDX_REM_ADDR directs SCTP to remove the given
addresses from the association. A caller may not remove all addresses from an
association. It will fail with
EINVAL.
On success, 0 is returned. On failure, -1 is returned, and
errno is set
appropriately.
- EBADF
-
sd is not a valid descriptor.
- ENOTSOCK
-
sd is a descriptor for a file, not a socket.
- EFAULT
- Error while copying in or out from the user address
space.
- EINVAL
- Invalid port or address or trying to remove all addresses
from an association.
- EACCES
- The address is protected, and the user is not the
super-user.
