SCTP_SEND(3SOCKET) Sockets Library Functions SCTP_SEND(3SOCKET)

sctp_send - send message from an SCTP socket

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

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.

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.
