SCTP_BINDX(3) Linux Programmer's Manual SCTP_BINDX(3)NAMEsctp_bindx - Add or remove bind addresses on a socket.
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);
DESCRIPTIONsctp_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 sock‐
addr_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 as‐
sociate 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 associa‐
tion. It will fail with EINVAL.
RETURN VALUE
On success, 0 is returned. On failure, -1 is returned, and errno is set
appropriately.
ERRORS
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.
