SCTP_BINDX(3)						   BSD 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 argu-
     ment 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 asso-
     ciations in the endpoint will attempt to have the address(es) added dynamically to the existing association.

RETURN VALUES

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

ERRORS

     The sctp_bindx() function 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.
