sctp_recvmsg(3SOCKET)					     Sockets Library Functions					     sctp_recvmsg(3SOCKET)

NAME

       sctp_recvmsg - receive 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_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.
