NAME

       sctp_bindx - add or remove IP addresses to or from an SCTP socket

SYNOPSIS

       cc [ flag... ] file... -lsocket -lnsl -lsctp [ library... ]
       #include <sys/types.h>
       #include <sys/socket.h>
       #include <netinet/sctp.h>

       int sctp_bindx(int sock, void *addrs, int addrcnt, int flags);

DESCRIPTION

       The  sctp_bindx()  function  adds  or removes addresses to or from an SCTP socket. If sock is an Internet Protocol Version 4 (IPv4) socket,
       addrs should be an array of sockaddr_in structures containing IPv4 addresses. If sock is an Internet  Protocol  Version	6  (IPv6)  socket,
       addrs  should be an array of sockaddr_in6 structures containing IPv6 or IPv4-mapped IPv6 addresses. The addrcnt is the number of array ele-
       ments in addrs.	The family of the address type is used with addrcnt to determine the size of the array.

       The flags parameter is a bitmask that indicates whether addresses are to be added or removed from a socket. The flags parameter	is  formed
       by bitwise OR of zero or more of the following flags:

       SCTP_BINDX_ADD_ADDR     Indicates that addresses from addrs should be added to the SCTP socket.

       SCTP_BINDX_REM_ADDR     Indicates that addresses from addrs should be removed from the SCTP socket.

       These  two  flags  are  mutually  exclusive.  If  flags	is formed by a bitwise OR of both SCTP_BINDX_ADD_ADDR and SCTP_BINDX_REM_ADDR, the
       sctp_bindx() function will fail.

       Prior to calling sctp_bindx() on an SCTP endpoint, the endpoint should be bound using bind(3SOCKET).  On  a  listening  socket,	a  special
       INADDR_ANY  value for IP or an unspecified address of all zeros for IPv6 can be used in addrs to add all IPv4 or IPv6 addresses on the sys-
       tem to the socket.  The sctp_bindx() function can also be used to add or remove addresses to or from an established association. In such  a
       case,  messages are exchanged between the SCTP endpoints to update the address lists for that association if both endpoints support dynamic
       address reconfiguration.

RETURN VALUES

       Upon successful completion, the sctp_bindx() function returns 0. Otherwise, the function returns -1 and sets errno to indicate the error.

ERRORS

       The sctp_bindx() call fails under the following conditions.

       EBADF	       The sock argument is an invalid file descriptor.

       ENOTSOCK        The sock argument is not a socket.

       EINVAL	       One or more of the IPv4 or IPv6 addresses is invalid.

       EINVAL	       The endpoint is not bound.

       EINVAL	       The last address is requested to be removed from an established association.
