SCTP_GENERIC_RECVMSG(2) 				      BSD System Calls Manual					   SCTP_GENERIC_RECVMSG(2)

NAME

     sctp_generic_recvmsg -- receive data from a peer

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <sys/types.h>
     #include <sys/socket.h>
     #include <netinet/sctp.h>

     int
     sctp_generic_recvmsg(int s, struct iovec *iov, int iovlen, struct sockaddr *from, socklen_t *fromlen, struct sctp_sndrcvinfo *sinfo,
	 int *msgflags);

DESCRIPTION

     sctp_generic_recvmsg() is the true system call used by the sctp_recvmsg(3) function call.	This call is more efficient since it is a true
     system call but it is specific to FreeBSD and can be expected not to be present on any other operating system.  For detailed usage please see
     the sctp_recvmsg(3) function call.

RETURN VALUES

     The call returns the number of bytes read on success and -1 upon failure.

ERRORS

     [EBADF]		The argument s is not a valid descriptor.

     [ENOTSOCK] 	The argument s is not a socket.

SCTP_RECVMSG(3)                                              Linux Programmer's Manual                                             SCTP_RECVMSG(3)

NAME

       sctp_recvmsg - Receive a message from a SCTP socket.

SYNOPSIS

       #include <sys/types.h>
       #include <sys/socket.h>
       #include <netinet/sctp.h>

       int sctp_recvmsg(int sd, void * msg, size_t len,
                        struct sockaddr * from, socklen_t * fromlen,
                        struct sctp_sndrcvinfo * sinfo, int * msg_flags);

DESCRIPTION

       sctp_recvmsg  is  a wrapper library function that can be used to receive a message from a socket while using the advanced features of SCTP.
       sd is the socket descriptor on which the message pointed to by msg of length len is received.

       If from is not NULL, the source address of the message is filled in. The argument fromlen is a value-result parameter. initialized  to  the
       size of the buffer associated with from , and modified on return to indicate the actual size of the address stored.

       sinfo  is  a  pointer to a sctp_sndrcvinfo structure to be filled upon receipt of the message.  msg_flags is a pointer to a integer that is
       filled with any message flags like MSG_NOTIFICATION or MSG_EOR.

RETURN VALUE

       On success, sctp_recvmsg returns the number of bytes received or -1 if an error occurred.
