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  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.

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.
