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.
