sctp_send(3C)

Name

sctp_send - send message from an SCTP socket

Synopsis

cc [ flag... ] file... –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(3C)

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

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.
