ssize_t sctp_send(int s, const void *msg, size_t *len,
const struct sctp_sndrcvinfo *sinfo, int flags);
The sctp_send() function sends messages from one-to-one and one-to-many
style SCTP endpoints. The following parameters can be set:
s
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.
Upon successful completion, the sctp_send() function returns the number
of bytes sent. The function returns -1 if an error occurs.
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.
