+ *
+ * recvmsg receives a message using recvmsg(2) system call in blocking manner.
+ *
+ * _maxmesglen_ is the maximum length of mesg to receive.
+ *
+ * _flags_ is bitwise OR of MSG_* constants such as Socket::MSG_PEEK.
+ *
+ * _maxcontrollen_ is the maximum length of controls (ancillary data) to receive.
+ *
+ * _opts_ is option hash.
+ * Currently :scm_rights=>bool is the only option.
+ *
+ * :scm_rights option specifies that application expects SCM_RIGHTS control message.
+ * If the value is nil or false, application don't expects SCM_RIGHTS control message.
+ * In this case, recvmsg closes the passed file descriptors immediately.
+ * This is the default behavior.
+ *
+ * If :scm_rights value is neither nil nor false, application expects SCM_RIGHTS control message.
+ * In this case, recvmsg creates IO objects for each file descriptors for
+ * Socket::AncillaryData#unix_rights method.
+ *
+ * The return value is 4-elements array.
+ *
+ * _mesg_ is a string of the received message.
+ *
+ * _sender_addrinfo_ is a sender socket address for connection-less socket.
+ * It is an Addrinfo object.
+ * For connection-oriented socket such as TCP, sender_addrinfo is platform dependent.
+ *
+ * _rflags_ is a flags on the received message which is bitwise OR of MSG_* constants such as Socket::MSG_TRUNC.
+ * It will be nil if the system uses 4.3BSD style old recvmsg system call.
+ *
+ * _controls_ is ancillary data which is an array of Socket::AncillaryData objects such as:
+ *
+ * #<Socket::AncillaryData: AF_UNIX SOCKET RIGHTS 7>
+ *
+ * _maxmesglen_ and _maxcontrollen_ can be nil.
+ * In that case, the buffer will be grown until the message is not truncated.
+ * Internally, MSG_PEEK is used and MSG_TRUNC/MSG_CTRUNC are checked.
+ *
+ * recvmsg can be used to implement recv_io as follows:
+ *
+ * mesg, sender_sockaddr, rflags, *controls = sock.recvmsg(:scm_rights=>true)

+ * Document-method: setsockopt
+ * call-seq:
+ * setsockopt(level, optname, optval)
+ * setsockopt(socketoption)
+ *
+ * Sets a socket option. These are protocol and system specific, see your
+ * local system documentation for details.
+ *
+ * === Parameters
+ * * +level+ is an integer, usually one of the SOL_ constants such as
+ * Socket::SOL_SOCKET, or a protocol level.
+ * A string or symbol of the name, possibly without prefix, is also
+ * accepted.
+ * * +optname+ is an integer, usually one of the SO_ constants, such
+ * as Socket::SO_REUSEADDR.
+ * A string or symbol of the name, possibly without prefix, is also
+ * accepted.
+ * * +optval+ is the value of the option, it is passed to the underlying
+ * setsockopt() as a pointer to a certain number of bytes. How this is
+ * done depends on the type:
+ * - Fixnum: value is assigned to an int, and a pointer to the int is
+ * passed, with length of sizeof(int).
+ * - true or false: 1 or 0 (respectively) is assigned to an int, and the
+ * int is passed as for a Fixnum. Note that +false+ must be passed,
+ * not +nil+.
+ * - String: the string's data and length is passed to the socket.
+ * * +socketoption+ is an instance of Socket::Option
+ *
+ * === Examples
+ *
+ * Some socket options are integers with boolean values, in this case
+ * #setsockopt could be called like this:
+ * sock.setsockopt(:SOCKET, :REUSEADDR, true)
+ * sock.setsockopt(Socket::SOL_SOCKET,Socket::SO_REUSEADDR, true)
+ * sock.setsockopt(Socket::Option.bool(:INET, :SOCKET, :REUSEADDR, true))
+ *
+ * Some socket options are integers with numeric values, in this case
+ * #setsockopt could be called like this:
+ * sock.setsockopt(:IP, :TTL, 255)
+ * sock.setsockopt(Socket::IPPROTO_IP, Socket::IP_TTL, 255)
+ * sock.setsockopt(Socket::Option.int(:INET, :IP, :TTL, 255))
+ *
+ * Option values may be structs. Passing them can be complex as it involves
+ * examining your system headers to determine the correct definition. An
+ * example is an +ip_mreq+, which may be defined in your system headers as:
+ * struct ip_mreq {

+ * socket option for IPv4 multicast is bit confusing.
+ *
+ * IP Multicast is implemented by Steve Deering at first:
+ * IP Multicast Extensions for 4.3BSD UNIX and related systems
+ * (MULTICAST 1.2 Release)
+ * http://www.kohala.com/start/mcast.api.txt
+ *
+ * There are 3 socket options which takes a struct.
+ *
+ * IP_MULTICAST_IF: struct in_addr
+ * IP_ADD_MEMBERSHIP: struct ip_mreq
+ * IP_DROP_MEMBERSHIP: struct ip_mreq
+ *
+ * But they uses an IP address to specify an interface.
+ * This means the API cannot specify an unnumbered interface.
+ *
+ * Linux 2.4 introduces struct ip_mreqn to fix this problem.
+ * struct ip_mreqn has imr_ifindex field to specify interface index.
+ *
+ * IP_MULTICAST_IF: struct ip_mreqn
+ * IP_ADD_MEMBERSHIP: struct ip_mreqn
+ * IP_DROP_MEMBERSHIP: struct ip_mreqn
+ *
+ * FreeBSD 7 obtained struct ip_mreqn for IP_MULTICAST_IF.
+ * http://www.FreeBSD.org/cgi/cvsweb.cgi/src/sys/netinet/in.h.diff?r1=1.99;r2=1.100
+ *
+ * Another hackish workaround is "RFC 1724 hack".
+ * RFC 1724 section 3.3 suggests unnumbered interfaces
+ * specified by pseudo address 0.0.0.0/8.
+ * NetBSD 4 and FreeBSD 5 documented it.
+ * http://cvsweb.netbsd.org/cgi-bin/cvsweb.cgi/src/share/man/man4/ip.4.diff?r1=1.16&r2=1.17
+ * http://www.FreeBSD.org/cgi/cvsweb.cgi/src/share/man/man4/ip.4.diff?r1=1.37;r2=1.38
+ * FreeBSD 7.0 removed it.
+ * http://www.FreeBSD.org/cgi/cvsweb.cgi/src/share/man/man4/ip.4.diff?r1=1.49;r2=1.50
+ *
+ * RFC 1724 hack is not supported by Socket::Option#inspect because
+ * it is not distinguishable by the size.

+ * Addrinfo.new(sockaddr, family, socktype, protocol) => addrinfo
+ *
+ * returns a new instance of Addrinfo.
+ * The instance contains sockaddr, family, socktype, protocol.
+ * sockaddr means struct sockaddr which can be used for connect(2), etc.
+ * family, socktype and protocol are integers which is used for arguments of socket(2).
+ *
+ * sockaddr is specified as an array or a string.
+ * The array should be compatible to the value of IPSocket#addr or UNIXSocket#addr.
+ * The string should be struct sockaddr as generated by
+ * Socket.sockaddr_in or Socket.unpack_sockaddr_un.
+ *
+ * sockaddr examples:
+ * - ["AF_INET", 46102, "localhost.localdomain", "127.0.0.1"]
+ * - ["AF_INET6", 42304, "ip6-localhost", "::1"]
+ * - ["AF_UNIX", "/tmp/sock"]
+ * - Socket.sockaddr_in("smtp", "2001:DB8::1")
+ * - Socket.sockaddr_in(80, "172.18.22.42")
+ * - Socket.sockaddr_in(80, "www.ruby-lang.org")
+ * - Socket.sockaddr_un("/tmp/sock")
+ *
+ * In an AF_INET/AF_INET6 sockaddr array, the 4th element,
+ * numeric IP address, is used to construct socket address in the Addrinfo instance.
+ * If the 3rd element, textual host name, is non-nil, it is also recorded but used only for Addrinfo#inspect.
+ *
+ * family is specified as an integer to specify the protocol family such as Socket::PF_INET.
+ * It can be a symbol or a string which is the constant name
+ * with or without PF_ prefix such as :INET, :INET6, :UNIX, "PF_INET", etc.
+ * If omitted, PF_UNSPEC is assumed.
+ *
+ * socktype is specified as an integer to specify the socket type such as Socket::SOCK_STREAM.
+ * It can be a symbol or a string which is the constant name
+ * with or without SOCK_ prefix such as :STREAM, :DGRAM, :RAW, "SOCK_STREAM", etc.
+ * If omitted, 0 is assumed.
+ *
+ * protocol is specified as an integer to specify the protocol such as Socket::IPPROTO_TCP.
+ * It must be an integer, unlike family and socktype.
+ * If omitted, 0 is assumed.
+ * Note that 0 is reasonable value for most protocols, except raw socket.

+ * * Errno::ENOBUFS - insufficient resources were available in the system to

+ * * Errno::ENOMEM - insufficient memory was available to fulfill the request

+ * * Errno::ENOTCONN - a receive is attempted on a connection-mode socket that

+ * * Errno::ENOTSOCK - the +socket+ does not refer to a socket
+ * * Errno::EOPNOTSUPP - the specified flags are not supported for this socket type
+ * * Errno::ETIMEDOUT - the connection timed out during connection establishment

+ *
+ * === Windows Exceptions
+ * On Windows systems the following system exceptions may be raised if
+ * the call to _recvfrom_ fails:
+ * * Errno::ENETDOWN - the network is down
+ * * Errno::EFAULT - the internal buffer and from parameters on +socket+ are not
+ * part of the user address space, or the internal fromlen parameter is
+ * too small to accommodate the peer address
+ * * Errno::EINTR - the (blocking) call was cancelled by an internal call to
+ * the WinSock function WSACancelBlockingCall
+ * * Errno::EINPROGRESS - a blocking Windows Sockets 1.1 call is in progress or
+ * the service provider is still processing a callback function
+ * * Errno::EINVAL - +socket+ has not been bound with a call to _bind_, or an
+ * unknown flag was specified, or MSG_OOB was specified for a socket with
+ * SO_OOBINLINE enabled, or (for byte stream-style sockets only) the internal
+ * len parameter on +socket+ was zero or negative
+ * * Errno::EISCONN - +socket+ is already connected. The call to _recvfrom_ is
+ * not permitted with a connected socket on a socket that is connection
+ * oriented or connectionless.
+ * * Errno::ENETRESET - the connection has been broken due to the keep-alive
+ * activity detecting a failure while the operation was in progress.
+ * * Errno::EOPNOTSUPP - MSG_OOB was specified, but +socket+ is not stream-style
+ * such as type SOCK_STREAM. OOB data is not supported in the communication
+ * domain associated with +socket+, or +socket+ is unidirectional and
+ * supports only send operations
+ * * Errno::ESHUTDOWN - +socket+ has been shutdown. It is not possible to
+ * call _recvfrom_ on a socket after _shutdown_ has been invoked.
+ * * Errno::EWOULDBLOCK - +socket+ is marked as nonblocking and a call to
+ * _recvfrom_ would block.
+ * * Errno::EMSGSIZE - the message was too large to fit into the specified buffer
+ * and was truncated.
+ * * Errno::ETIMEDOUT - the connection has been dropped, because of a network
+ * failure or because the system on the other end went down without
+ * notice
+ * * Errno::ECONNRESET - the virtual circuit was reset by the remote side
+ * executing a hard or abortive close. The application should close the
+ * socket; it is no longer usable. On a UDP-datagram socket this error
+ * indicates a previous send operation resulted in an ICMP Port Unreachable

+ /*
+ * Document-class: Socket < BasicSocket
+ *
+ * Class +Socket+ provides access to the underlying operating system
+ * socket implementations. It can be used to provide more operating system
+ * specific functionality than the protocol-specific socket classes.
+ *
+ * The constants defined under Socket::Constants are also defined under
+ * Socket. For example, Socket::AF_INET is usable as well as
+ * Socket::Constants::AF_INET. See Socket::Constants for the list of
+ * constants.
+ *
+ * === What's a socket?
+ *
+ * Sockets are endpoints of a bidirectionnal communication channel.
+ * Sockets can communicate within a process, between processes on the same
+ * machine or between different machines. There are many types of socket:
+ * TCPSocket, UDPSocket or UNIXSocket for example.
+ *
+ * Sockets have their own vocabulary:
+ * domain::
+ * The family of protocols: Socket::PF_INET, Socket::PF_INET6,
+ * Socket::PF_UNIX, etc.
+ * type::
+ * The type of communications between the two endpoints, typically
+ * Socket::SOCK_STREAM or Socket::SOCK_DGRAM.
+ * protocol::
+ * Typically zero. This may be used to identify a variant of a
+ * protocol.
+ * hostname::
+ * The identifier of a network interface:
+ * * a string (hostname, IPv4 or IPv6 adress or <tt><broadcast></tt>
+ * which specifies a broadcast address)
+ * * a zero-length string which specifies INADDR_ANY
+ * * an integer (interpreted as binary address in host byte order).
+ *
+ * === Quick start
+ *
+ * Some classes such as TCPSocket, UDPSocket or UNIXSocket ease use of
+ * sockets of these types compared to C programming.
+ *
+ * # Creating a TCP socket in a C-like manner
+ * s = Socket.new Socket::INET, Socket::SOCK_STREAM
+ * s.connect Socket.pack_sockaddr_in(80, 'example.com')
+ *
+ * # Using TCPSocket
+ * s = TCPSocket.new 'example.com', 80
+ *
+ * A simple server would look like:
+ *
+ * require 'socket'
+ *
+ * server = TCPServer.new 2000 # Server bound to port 2000
+ *
+ * loop do
+ * client = server.accept # Wait for a client to connect
+ * client.puts "Hello !"
+ * client.puts "Time is #{Time.now}"
+ * client.close
+ * end
+ *
+ * A simple client may look like:
+ *
+ * require 'socket'
+ *
+ * s = TCPSocket.new 'localhost', 2000
+ *
+ * while line = s.gets # Read lines from socket
+ * puts line # and print them
+ * end
+ *
+ * s.close # close socket when done
+ *
+ * === Exception Handling
+ *
+ * Ruby's Socket implementation raises exceptions based on the error
+ * generated by the system dependent implementation. This is why the
+ * methods are documented in a way that isolate Unix-based system
+ * exceptions from Windows based exceptions. If more information on
+ * particular exception is needed please refer to the Unix manual pages or
+ * the Windows WinSock reference.
+ *
+ * === Convenient methods
+ *
+ * Although the general way to create socket is Socket.new,
+ * there are several methods for socket creation for most cases.
+ *
+ * TCP client socket::
+ * Socket.tcp, TCPSocket.open
+ * TCP server socket::
+ * Socket.tcp_server_loop, TCPServer.open
+ * UNIX client socket::
+ * Socket.unix, UNIXSocket.open
+ * UNIX server socket::
+ * Socket.unix_server_loop, UNIXServer.open
+ *
+ * === Documentation by
+ *
+ * * Zach Dennis
+ * * Sam Roberts
+ * * <em>Programming Ruby</em> from The Pragmatic Bookshelf.
+ *
+ * Much material in this documentation is taken with permission from
+ * <em>Programming Ruby</em> from The Pragmatic Bookshelf.
