sctp_send(3SOCKET)					     Sockets Library Functions						sctp_send(3SOCKET)

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_recvmsg - receive 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_recvmsg(int s, void *msg, size_t len, struct sockaddr *from,
	    socklen_t *fromlen, struct sctp_sndrcvinfo *sinfo, int *msg_flags);

DESCRIPTION

       The sctp_recvmsg() function receives a message from the SCTP endpoint s.

       In addition to specifying the message buffer msg and the length len of the buffer, the following parameters can be set:

       from	    Pointer to an address, filled in with the sender's address

       fromlen	    Size of the buffer associated with the from parameter

       sinfo	    Pointer to an sctp_sndrcvinfo structure, filled in upon the receipt of the message

       msg_flags    Message flags such as MSG_CTRUNC, MSG_NOTIFICATION, MSG_EOR

       The  sinfo  parameter  is  filled  in  only  when the caller has enabled sctp_data_io_events by calling setsockopt() with the socket option
       SCTP_EVENTS.

RETURN VALUES

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

ERRORS

       The sctp_recvmsg() 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_OOB is set as a flag.

       ENOTCONN      There is no established association.
