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_NOTIFICATION,
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.
