SCTP_SEND(3SOCKET)SCTP_SEND(3SOCKET)NAMEsctp_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.
