SYNOPSIS
cc [ flag... ] file... -lsocket -lnsl -lsctp [ library... ]
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/sctp.h>
ssize_t sctp_recvmsg(int s, void *msg, size_t len, struct sockaddr
*from, socklen_t *fromlen, struct sctp_sndrcvinfo *sinfo, int
*msg_flags);
DESCRIPTION
The sctp_recvmsg() function receives a message from the SCTP endpoint
s.
In addition to specifying the message buffer msg and the length len of
the buffer, the following parameters can be set:
from Pointer to an address, filled in with the
sender's address
fromlen Size of the buffer associated with the from
parameter
sinfo Pointer to an sctp_sndrcvinfo structure, filled
in upon the receipt of the message
msg_flags Message flags such as MSG_CTRUNC, MSG_NOTIFICA‐
TION, MSG_EOR
The sinfo parameter is filled in only when the caller has enabled
sctp_data_io_events by calling setsockopt() with the socket option
SCTP_EVENTS.
RETURN VALUES
Upon successful completion, the sctp_recvmsg() function returns the
number of bytes received. The function returns -1 if an error occurs.
ERRORS
The sctp_recvmsg() 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_OOB is set as a flag.
ENOTCONN There is no established association.
