NAME
       sctp_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);

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 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
       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	asso-
       ciation. 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.
