The .Fa fromlen argument is a value-result argument, initialized to the size of the buffer associated with .Fa from , and modified on return to indicate the actual size of the address stored there. .Pp The .Fn recv function is normally used only on a .Em connected socket (see .Xr connect 2 ) and is identical to .Fn recvfrom with a null pointer passed as its .Fa from argument. .Pp -All three routines return the length of the message on successful -completion. +The +.Fn recvmmsg +function is used to receive multiple +messages at a call. +Their number is supplied by +.Fa vlen . +The messages are placed in the buffers described by +.Fa msgvec +vector, after reception. +The size of each received message is placed in the +.Fa msg_len +field of each element of the vector. +If +.Fa timeout +is NULL the call blocks until the data is available for each +supplied message buffer. +Otherwise it waits for data for the specified amount of time. +If the timeout expired and there is no data received, +a value 0 is returned. +The +.Xr ppoll 2 +system call is used to implement the timeout mechanism, +before first receive is performed. +.Pp +The +.Fn recv , +.Fn recvfrom +and +.Fn recvmsg +return the length of the message on successful +completion, whereas +.Fn recvmmsg +returns the number of received messages. If a message is too long to fit in the supplied buffer, excess bytes may be discarded depending on the type of socket the message is received from (see .Xr socket 2 ) . .Pp If no messages are available at the socket, the receive call waits for a message to arrive, unless the socket is non-blocking (see .Xr fcntl 2 ) in which case the value \-1 is returned and the global variable .Va errno is set to .Er EAGAIN . -The receive calls normally return any data available, +The receive calls except +.Fn recvmmsg +normally return any data available, up to the requested amount, rather than waiting for receipt of the full amount requested; this behavior is affected by the socket-level options .Dv SO_RCVLOWAT and .Dv SO_RCVTIMEO described in .Xr getsockopt 2 . +The +.Fn recvmmsg +function implements this behaviour for each message in the vector. .Pp The .Xr select 2 system call may be used to determine when more data arrives. .Pp The .Fa flags argument to a .Fn recv function is formed by .Em or Ap ing one or more of the values: .Bl -column ".Dv MSG_CMSG_CLOEXEC" -offset indent .It Dv MSG_OOB Ta process out-of-band data .It Dv MSG_PEEK Ta peek at incoming message .It Dv MSG_WAITALL Ta wait for full request or error .It Dv MSG_DONTWAIT Ta do not block .It Dv MSG_CMSG_CLOEXEC Ta set received fds close-on-exec +.It Dv MSG_WAITFORONE Ta do not block after receiving the first message +(only for +.Fn recvmmsg +) .El .Pp The .Dv MSG_OOB flag requests receipt of out-of-band data that would not be received in the normal data stream. Some protocols place expedited data at the head of the normal data queue, and thus this flag cannot be used with such protocols. The .Dv MSG_PEEK flag causes the receive operation to return data from the beginning of the receive queue without removing that data from the queue. Thus, a subsequent receive call will return the same data. The .Dv MSG_WAITALL flag requests that the operation block until the full request is satisfied. However, the call may still return less data than requested if a signal is caught, an error or disconnect occurs, or the next data to be received is of a different type than that returned. The .Dv MSG_DONTWAIT flag requests the call to return when it would block otherwise. If no data is available, .Va errno is set to .Er EAGAIN . This flag is not available in strict .Tn ANSI or C99 compilation mode. +The +.Dv MSG_WAITFORONE +flag sets MSG_DONTWAIT after the first message has been received. +This flag is only relevant for +.Fn recvmmsg . .Pp The .Fn recvmsg system call uses a .Fa msghdr structure to minimize the number of directly supplied arguments. This structure has the following form, as defined in .In sys/socket.h : .Bd -literal struct msghdr { void *msg_name; /* optional address */ socklen_t msg_namelen; /* size of address */ struct iovec *msg_iov; /* scatter/gather array */ int msg_iovlen; /* # elements in msg_iov */ void *msg_control; /* ancillary data, see below */ socklen_t msg_controllen;/* ancillary data buffer len */ int msg_flags; /* flags on received message */ }; .Ed .Pp Here .Fa msg_name and .Fa msg_namelen specify the destination address if the socket is unconnected; .Fa msg_name may be given as a null pointer if no names are desired or required. The .Fa msg_iov and .Fa msg_iovlen arguments describe scatter gather locations, as discussed in .Xr read 2 . The .Fa msg_control argument, which has length .Fa msg_controllen , points to a buffer for other protocol control related messages or other miscellaneous ancillary data. The messages are of the form: .Bd -literal struct cmsghdr { socklen_t cmsg_len; /* data byte count, including hdr */ int cmsg_level; /* originating protocol */ int cmsg_type; /* protocol-specific type */ /* followed by u_char cmsg_data[]; */ }; .Ed .Pp As an example, one could use this to learn of changes in the data-stream in XNS/SPP, or in ISO, to obtain user-connection-request data by requesting a .Fn recvmsg with no data buffer provided immediately after an .Fn accept system call. .Pp Open file descriptors are now passed as ancillary data for .Dv AF_UNIX domain sockets, with .Fa cmsg_level set to .Dv SOL_SOCKET and .Fa cmsg_type set to .Dv SCM_RIGHTS . The close-on-exec flag on received descriptors is set according to the .Dv MSG_CMSG_CLOEXEC flag passed to .Fn recvmsg . .Pp Process credentials can also be passed as ancillary data for .Dv AF_UNIX domain sockets using a .Fa cmsg_type of .Dv SCM_CREDS . In this case, .Fa cmsg_data should be a structure of type .Fa cmsgcred , which is defined in .In sys/socket.h as follows: .Bd -literal struct cmsgcred { pid_t cmcred_pid; /* PID of sending process */ uid_t cmcred_uid; /* real UID of sending process */ uid_t cmcred_euid; /* effective UID of sending process */ gid_t cmcred_gid; /* real GID of sending process */ short cmcred_ngroups; /* number or groups */ gid_t cmcred_groups[CMGROUP_MAX]; /* groups */ }; .Ed .Pp If a sender supplies ancillary data with enough space for the above struct tagged as .Dv SCM_CREDS control message type to the .Fn sendmsg system call, then kernel will fill in the credential information of the sending process and deliver it to the receiver. Since receiver usually has no control over a sender, this method of retrieving credential information isn't reliable. For reliable retrieval of remote side credentials it is advised to use the .Dv LOCAL_CREDS socket option on the receiving socket. See .Xr unix 4 for details. .Pp The .Fa msg_flags field is set on return according to the message received. .Dv MSG_EOR indicates end-of-record; the data returned completed a record (generally used with sockets of type .Dv SOCK_SEQPACKET ) . .Dv MSG_TRUNC indicates that the trailing portion of a datagram was discarded because the datagram was larger than the buffer supplied. .Dv MSG_CTRUNC indicates that some control data were discarded due to lack of space in the buffer for ancillary data. .Dv MSG_OOB is returned to indicate that expedited or out-of-band data were received. +.Pp +The +.Fn recvmmsg +system call uses the +.Fa mmsghdr +structure, defined as follows in the +.In sys/socket.h +header : +.Bd -literal +struct mmsghdr { + struct msghdr msg_hdr; /* message header */ + ssize_t msg_len; /* message length */ +}; +.Ed +.Pp +On data reception the +.Fa msg_len +field is updated to the length of the received message. .Sh RETURN VALUES -These calls return the number of bytes received, or -1 -if an error occurred. +These calls except +.Fn recvmmsg +return the number of bytes received. +.Fn recvmmsg +returns the number of messages received. +A value of -1 is returned if an error occurred. .Sh ERRORS The calls fail if: .Bl -tag -width Er .It Bq Er EBADF The argument .Fa s is an invalid descriptor. .It Bq Er ECONNRESET The remote socket end is forcibly closed. .It Bq Er ENOTCONN The socket is associated with a connection-oriented protocol and has not been connected (see .Xr connect 2 and .Xr accept 2 ) . .It Bq Er ENOTSOCK The argument .Fa s does not refer to a socket. .It Bq Er EMSGSIZE The .Fn recvmsg system call was used to receive rights (file descriptors) that were in flight on the connection. However, the receiving program did not have enough free file descriptor slots to accept them. In this case the descriptors are closed, any pending data can be returned by another call to .Fn recvmsg . .It Bq Er EAGAIN The socket is marked non-blocking and the receive operation would block, or a receive timeout had been set and the timeout expired before data were received. .It Bq Er EINTR The receive was interrupted by delivery of a signal before any data were available. .It Bq Er EFAULT The receive buffer pointer(s) point outside the process's address space. .El .Sh SEE ALSO .Xr fcntl 2 , .Xr getsockopt 2 , .Xr read 2 , .Xr select 2 , .Xr socket 2 , .Xr unix 4 .Sh HISTORY The .Fn recv function appeared in .Bx 4.2 . +The +.Fn recvmmsg +function appeared in +.Fx 11.0 .

The .Fn send function may be used only when the socket is in a .Em connected state, while -.Fn sendto -and +.Fn sendto , .Fn sendmsg +and +.Fn sendmmsg may be used at any time. .Pp The address of the target is given by .Fa to with .Fa tolen specifying its size. The length of the message is given by .Fa len . If the message is too long to pass atomically through the underlying protocol, the error .Er EMSGSIZE is returned, and the message is not transmitted. .Pp +The +.Fn sendmmsg +function sends multiple messages at a call. +They are given by the +.Fa msgvec +vector along with +.Fa vlen +specifying the vector size. +The number of octets sent per each message is placed in the +.Fa msg_len +field of each processed element of the vector after transmission. +.Pp No indication of failure to deliver is implicit in a .Fn send . Locally detected errors are indicated by a return value of -1. .Pp If no messages space is available at the socket to hold the message to be transmitted, then .Fn send normally blocks, unless the socket has been placed in non-blocking I/O mode. The .Xr select 2 system call may be used to determine when it is possible to send more data. .Pp The .Fa flags argument may include one or more of the following: .Bd -literal #define MSG_OOB 0x00001 /* process out-of-band data */ #define MSG_DONTROUTE 0x00004 /* bypass routing, use direct interface */ #define MSG_EOR 0x00008 /* data completes record */ #define MSG_EOF 0x00100 /* data completes transaction */ #define MSG_NOSIGNAL 0x20000 /* do not generate SIGPIPE on EOF */ .Ed .Pp The flag .Dv MSG_OOB is used to send .Dq out-of-band data on sockets that support this notion (e.g.\& .Dv SOCK_STREAM ) ; the underlying protocol must also support .Dq out-of-band data. .Dv MSG_EOR is used to indicate a record mark for protocols which support the concept. .Dv MSG_EOF requests that the sender side of a socket be shut down, and that an appropriate indication be sent at the end of the specified data; this flag is only implemented for .Dv SOCK_STREAM sockets in the .Dv PF_INET protocol family. .Dv MSG_DONTROUTE is usually used only by diagnostic or routing programs. .Dv MSG_NOSIGNAL is used to prevent .Dv SIGPIPE generation when writing a socket that may be closed. .Pp See .Xr recv 2 for a description of the .Fa msghdr +structure and the +.Fa mmsghdr structure. .Sh RETURN VALUES -The call returns the number of characters sent, or -1 -if an error occurred. +The +.Fn send , +.Fn sendto +and +.Fn sendmsg +calls +return the number of octets sent. +The +.Fn sendmmsg +call returns the number of messages sent. +If an error occurred a value of -1 is returned. .Sh ERRORS The .Fn send -function and +and +.Fn sendmmsg +functions and .Fn sendto and .Fn sendmsg system calls fail if: .Bl -tag -width Er .It Bq Er EBADF An invalid descriptor was specified. .It Bq Er EACCES The destination address is a broadcast address, and .Dv SO_BROADCAST has not been set on the socket. .It Bq Er ENOTSOCK The argument .Fa s is not a socket. .It Bq Er EFAULT An invalid user space address was specified for an argument. .It Bq Er EMSGSIZE The socket requires that message be sent atomically, and the size of the message to be sent made this impossible. .It Bq Er EAGAIN The socket is marked non-blocking and the requested operation would block. .It Bq Er ENOBUFS The system was unable to allocate an internal buffer. The operation may succeed when buffers become available. .It Bq Er ENOBUFS The output queue for a network interface was full. This generally indicates that the interface has stopped sending, but may be caused by transient congestion. .It Bq Er EHOSTUNREACH The remote host was unreachable. .It Bq Er EISCONN A destination address was specified and the socket is already connected. .It Bq Er ECONNREFUSED The socket received an ICMP destination unreachable message from the last message sent. This typically means that the receiver is not listening on the remote port. .It Bq Er EHOSTDOWN The remote host was down. .It Bq Er ENETDOWN The remote network was down. .It Bq Er EADDRNOTAVAIL The process using a .Dv SOCK_RAW socket was jailed and the source address specified in the IP header did not match the IP address bound to the prison. .It Bq Er EPIPE The socket is unable to send anymore data .Dv ( SBS_CANTSENDMORE has been set on the socket).

It is left to the application to implement an acknowledgment mechanism to prevent this from happening.
