SCTP_BINDX(3)						     Linux Programmer's Manual						     SCTP_BINDX(3)

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 asso-
       ciation.  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.

NAME

       sctp_getladdrs, sctp_freeladdrs - returns all locally bound addresses on an SCTP socket

SYNOPSIS

       cc [ flag... ] file... -lsocket -lnsl -lsctp [ library... ]
       #include <sys/types.h>
       #include <sys/socket.h>
       #include <netinet/sctp.h>

       int sctp_getladdrs(int sock, sctp_assoc_t id, void **addrs, void sctp_freeladdrs(void *addrs);

DESCRIPTION

       The  sctp_getladdrs()  function	queries addresses to which an SCTP socket is bound. The sctp_freeladdrs() function releases resources that
       are allocated to hold the addresses.

       The sctp_getladdrs() function returns all the locally bound addresses on the SCTP socket sock. On completion addrs points to a  dynamically
       allocated  array  of  sockaddr_in  structures for an Internet Protocol (IPv4) socket or an array of sockaddr_in6 structures for an Internet
       Protocol Version 6 (IPv6) socket. The addrs parameter must not be NULL. For an IPv4 SCTP socket, the addresses returned in the  sockaddr_in
       structures  are	IPv4 addresses. For an IPv6 SCTP socket, the addresses in the sockaddr_in6 structures can be IPv6 addresses or IPv4-mapped
       IPv6 addresses.

       If sock is a one-to-many style SCTP socket, id specifies the association of interest. A value of 0 to id  returns  locally-bound  addresses
       regardless of a particular association. If sock is a one-to-one style SCTP socket, id is ignored.

       The  sctp_freeladdrs()  function frees the resources allocated by sctp_getladdrs(). The addrs parameter is the array of addresses allocated
       by sctp_getladdrs().

RETURN VALUES

       Upon successful completion, the sctp_getladdrs() function returns the number of addresses in  the  addrs  array.  Otherwise,  the  function
       returns -1 and sets errno to indicate the error.

ERRORS

       The sctp_getladdrs() call fails under the following conditions.

       EBADF	       The sock argument is an invalid file descriptor.

       ENOTSOCK        The sock argument is not a socket.

       EINVAL	       The addrs argument is NULL.

       EINVAL	       The id argument is an invalid socket.
