SCTP_BINDX(3)	       FreeBSD Library Functions Manual		 SCTP_BINDX(3)

NAME
     sctp_bindx	-- bind	or unbind an SCTP socket to a list of addresses.

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <sys/types.h>
     #include <sys/socket.h>
     #include <netinet/sctp.h>

     int
     sctp_bindx(int s, struct sockaddr *addrs, int num,	int type);

DESCRIPTION
     The sctp_bindx() call binds or unbinds a address or a list	of addresses
     to	an SCTP	endpoint.  This	allows a user to bind a	subset of addresses.
     The sctp_bindx() call operates similarly to bind()	but allows a list of
     addresses and also	allows a bind or an unbind.  The argument s must be a
     valid SCTP	socket descriptor.  The	argument addrs is a list of addresses
     (where the	list may be only 1 in length) that the user wishes to bind or
     unbind to the socket.  The	argument type must be one of the following
     values.

     SCTP_BINDX_ADD_ADDR This value indicates that the listed address(es) need
     to	be added to the	endpoint.

     SCTP_BINDX_DEL_ADDR This value indicates that the listed address(es) need
     to	be removed from	the endpoint.

     Note that when a user adds	or deletes an address to an association	if the
     dynamic address flag net.inet.sctp.auto_asconf is enabled any associa-
     tions in the endpoint will	attempt	to have	the address(es)	added dynami-
     cally to the existing association.

RETURN VALUES
     The call returns 0	on success and -1 upon failure.

ERRORS
     The sctp_bindx() can return the following errors.

     [EINVAL]		This value is returned if the type field is not	one of
			the allowed values (see	above).

     [ENOMEM]		This value is returned if the number of	addresses
			being added causes a memory allocation failure in the
			call.

     [EBADF]		The argument s is not a	valid descriptor.

     [ENOTSOCK]		The argument s is not a	socket.
