NAME

       sctp_send - send message from an SCTP socket

SYNOPSIS

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

       ssize_t sctp_send(int s, const void *msg, size_t *len,
	    const struct sctp_sndrcvinfo *sinfo, int flags);

DESCRIPTION

       The sctp_send() function sends messages from one-to-one and one-to-many style SCTP endpoints. The following parameters can be set:

       s      Socket created by socket(3SOCKET)

       msg    Message to be sent

       len    Size of the message to be sent in bytes

       The  caller completes the sinfo parameter with values used to send a message. Such values might include the stream number, payload protocol
       identifier, time to live, and the SCTP message flag and context. For a one-to-many socket, the association ID can be specified in the sinfo
       parameter to send a message to the association represented in the ID.

       Flags supported for sctp_send() are reserved for future use.

RETURN VALUES

       Upon successful completion, the sctp_send() function returns the number of bytes sent. The function returns -1 if an error occurs.

ERRORS

       The sctp_send() function fails under the following conditions.

       EBADF	       The s argument is an invalid file descriptor.

       ENOTSOCK        The s argument is not a socket.

       EOPNOTSUPP      MSG_ABORT or MSG_EOF is set in the sinfo_flags field of sinfo for a one-to-one style SCTP socket.

       EPIPE	       The socket is shutting down and no more writes are allowed.

       EAGAIN	       The socket is non-blocking and the transmit queue is full.

       ENOTCONN        There is no established association.

       EINVAL	       Control message length is incorrect.

       EINVAL	       Specified destination address does not belong to the association.

       EINVAL	       The stream_no is outside the number of outbound streams supported by the association.

       EAFNOSUPPORT    Address family of the specified destination address is other than AF_INET or AF_INET6.

NAME

       sctp_getpaddrs, sctp_freepaddrs - returns all peer addresses on an SCTP association

SYNOPSIS

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

       int sctp_getpaddrs(int sock, sctp_assoc_t id, void **addrs, void sctp_freepaddrs(void *addrs);

DESCRIPTION

       The  sctp_getpaddrs()  queries  the peer addresses in an SCTP association. The sctp_freepaddrs() function releases resources that are allo-
       cated to hold the addresses.

       The sctp_getpaddrs() function returns all the peer addresses in the SCTP association identified by 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. If sock is a one-to-one  style  SCTP  socket,  id	is
       ignored.

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

RETURN VALUES

       Upon successful completion, the sctp_getpaddrs() 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_getpaddrs() succeeds unless one of the following conditions exist.

       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 association identifier for a one-to-many style STP socket.

       ENOTCONN        The specified socket is not connected.
