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.

full.

EINVAL
Control message length is incorrect.

EINVAL
Specified destination address does not belong to the
association.

The stream_no is outside the number of outbound
streams supported by the association.

EAFNOSUPPORT
