добавить или удалить адреса привязки на сокете (Add or remove bind addresses on a socket.)
Имя (Name)
sctp_bindx - Add or remove bind addresses on a socket.
Синопсис (Synopsis)
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/sctp.h>
int sctp_bindx(int sd, struct sockaddr * addrs, int addrcnt,
int flags);
Описание (Description)
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.
Возвращаемое значение (Return value)
On success, 0 is returned. On failure, -1 is returned, and errno
is set appropriately.
Ошибки (Error)
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.
