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.
