/*
|
|
* Document-method: setsockopt
|
|
* call-seq: setsockopt(level, optname, optval)
|
|
*
|
|
* Sets a socket option. These are protocol and system specific, see your
|
|
* local sytem documentation for details.
|
|
*
|
|
* === Parameters
|
|
* * +level+ is an integer, usually one of the SOL_ constants such as
|
|
* Socket::SOL_SOCKET, or a protocol level.
|
|
* * +optname+ is an integer, usually one of the SO_ constants, such
|
|
* as Socket::SO_REUSEADDR.
|
|
* * +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.
|
|
*
|
|
* === Examples
|
|
*
|
|
* Some socket options are integers with boolean values, in this case
|
|
* #setsockopt could be called like this:
|
|
* sock.setsockopt(Socket::SOL_SOCKET,Socket::SO_REUSEADDR, true)
|
|
*
|
|
* Some socket options are integers with numeric values, in this case
|
|
* #setsockopt could be called like this:
|
|
* sock.setsockopt(Socket::IPPROTO_IP, Socket::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 {
|
|
* struct in_addr imr_multiaddr;
|
|
* struct in_addr imr_interface;
|
|
* };
|
|
*
|
|
* In this case #setsockopt could be called like this:
|
|
* optval = IPAddr.new("224.0.0.251") + Socket::INADDR_ANY
|
|
* sock.setsockopt(Socket::IPPROTO_IP, Socket::IP_ADD_MEMBERSHIP, optval)

|
|
*
|
|
* Receives up to _maxlen_ bytes from +socket+ using recvfrom(2) after
|
|
* O_NONBLOCK is set for the underlying file descriptor.
|
|
* _flags_ is zero or more of the +MSG_+ options.
|
|
* The result, _mesg_, is the data received.
|
|
*
|
|
* When recvfrom(2) returns 0, Socket#recv_nonblock returns
|
|
* an empty string as data.
|
|
* The meaning depends on the socket: EOF on TCP, empty packet on UDP, etc.
|
|
*
|
|
* === Parameters
|
|
* * +maxlen+ - the number of bytes to receive from the socket
|
|
* * +flags+ - zero or more of the +MSG_+ options
|
|
*
|
|
* === Example
|
|
* serv = TCPServer.new("127.0.0.1", 0)
|
|
* af, port, host, addr = serv.addr
|
|
* c = TCPSocket.new(addr, port)
|
|
* s = serv.accept
|
|
* c.send "aaa", 0
|
|
* IO.select([s])
|
|
* p s.recv_nonblock(10) #=> "aaa"
|
|
*
|
|
* Refer to Socket#recvfrom for the exceptions that may be thrown if the call
|
|
* to _recv_nonblock_ fails.
|
|
*
|
|
* BasicSocket#recv_nonblock may raise any error corresponding to recvfrom(2) failure,
|
|
* including Errno::EWOULDBLOCK.
|

*

|
* === See

|
|
* udpsocket.recvfrom_nonblock(maxlen) => [mesg, sender_inet_addr]
|
|
* udpsocket.recvfrom_nonblock(maxlen, flags) => [mesg, sender_inet_addr]
|
|
*
|
|
* Receives up to _maxlen_ bytes from +udpsocket+ using recvfrom(2) after
|
|
* O_NONBLOCK is set for the underlying file descriptor.
|
|
* _flags_ is zero or more of the +MSG_+ options.
|
|
* The first element of the results, _mesg_, is the data received.
|
|
* The second element, _sender_inet_addr_, is an array to represent the sender address.
|
|
*
|
|
* When recvfrom(2) returns 0,
|
|
* Socket#recvfrom_nonblock returns an empty string as data.
|
|
* It means an empty packet.
|
|
*
|
|
* === Parameters
|
|
* * +maxlen+ - the number of bytes to receive from the socket
|
|
* * +flags+ - zero or more of the +MSG_+ options
|
|
*
|
|
* === Example
|
|
* require 'socket'
|
|
* s1 = UDPSocket.new
|
|
* s1.bind("127.0.0.1", 0)
|
|
* s2 = UDPSocket.new
|
|
* s2.bind("127.0.0.1", 0)
|
|
* s2.connect(*s1.addr.values_at(3,1))
|
|
* s1.connect(*s2.addr.values_at(3,1))
|
|
* s1.send "aaa", 0
|
|
* IO.select([s2])
|
|
* p s2.recvfrom_nonblock(10) #=> ["aaa", ["AF_INET", 33302, "localhost.localdomain", "127.0.0.1"]]
|
|
*
|
|
* Refer to Socket#recvfrom for the exceptions that may be thrown if the call
|
|
* to _recvfrom_nonblock_ fails.
|
|
*
|
|
* UDPSocket#recvfrom_nonblock may raise any error corresponding to recvfrom(2) failure,
|
|
* including Errno::EWOULDBLOCK.
|
|
*
|
|
* === See
|
|
* * Socket#recvfrom

|
|
* * Errno::EADDRNOTAVAIL - the specified _sockaddr_ is not available from the
|
|
* local machine
|
|
* * Errno::EAFNOSUPPORT - the specified _sockaddr_ is not a valid address for
|
|
* the address family of the specified +socket+
|
|
* * Errno::EALREADY - a connection is already in progress for the specified
|
|
* socket
|
|
* * Errno::EBADF - the +socket+ is not a valid file descriptor
|
|
* * Errno::ECONNREFUSED - the target _sockaddr_ was not listening for connections
|
|
* refused the connection request
|
|
* * Errno::ECONNRESET - the remote host reset the connection request
|
|
* * Errno::EFAULT - the _sockaddr_ cannot be accessed
|
|
* * Errno::EHOSTUNREACH - the destination host cannot be reached (probably
|
|
* because the host is down or a remote router cannot reach it)
|
|
* * Errno::EINPROGRESS - the O_NONBLOCK is set for the +socket+ and the
|
|
* connection cnanot be immediately established; the connection will be
|
|
* established asynchronously
|

|
|
* * Errno::EPROTOTYPE - the _sockaddr_ has a different type than the socket
|
|
* bound to the specified peer address
|
|
* * Errno::ETIMEDOUT - the attempt to connect time out before a connection
|
|
* was made.
|
|
*
|
|
* On unix-based systems if the address family of the calling +socket+ is
|
|
* AF_UNIX the follow exceptions may be raised if the call to _connect_
|
|
* fails:
|
|
* * Errno::EIO - an i/o error occured while reading from or writing to the
|
|
* file system
|
|
* * Errno::ELOOP - too many symbolic links were encountered in translating
|
|
* the pathname in _sockaddr_
|
|

|
|
* in progress on the +socket+.
|
|
* * Errno::EALREADY - see Errno::EINVAL
|
|
* * Errno::EADDRNOTAVAIL - the remote address is not a valid address, such as
|
|
* ADDR_ANY TODO check ADDRANY TO INADDR_ANY
|
|
* * Errno::EAFNOSUPPORT - addresses in the specified family cannot be used with

|
|
* * Errno::ECONNREFUSED - the target _sockaddr_ was not listening for connections
|

* call-seq:

|
* socket.listen( int ) => 0
|
|
*
|
|
* Listens for connections, using the specified +int+ as the backlog. A call
|
|
* to _listen_ only applies if the +socket+ is of type SOCK_STREAM or
|
|
* SOCK_SEQPACKET.
|
|
*
|
|
* === Parameter
|
|
* * +backlog+ - the maximum length of the queue for pending connections.
|
|
*
|
|
* === Example 1
|
|
* require 'socket'
|
|
* include Socket::Constants
|
|
* socket = Socket.new( AF_INET, SOCK_STREAM, 0 )
|
|
* sockaddr = Socket.pack_sockaddr_in( 2200, 'localhost' )
|
|
* socket.bind( sockaddr )
|
|
* socket.listen( 5 )
|
|
*
|
|
* === Example 2 (listening on an arbitary port, unix-based systems only):
|
|
* require 'socket'
|
|
* include Socket::Constants
|
|
* socket = Socket.new( AF_INET, SOCK_STREAM, 0 )
|
|
* socket.listen( 1 )
|
|
*
|
|
* === Unix-based Exceptions
|
|
* On unix based systems the above will work because a new +sockaddr+ struct
|
|
* is created on the address ADDR_ANY, for an arbitrary port number as handed
|
|
* off by the kernel. It will not work on Windows, because Windows requires that
|
|
* the +socket+ is bound by calling _bind_ before it can _listen_.
|
|
*
|
|
* If the _backlog_ amount exceeds the implementation-dependent maximum
|
|
* queue length, the implementation's maximum queue length will be used.
|
|
*
|
|
* On unix-based based systems the following system exceptions may be raised if the
|
|
* call to _listen_ fails:
|
|
* * Errno::EBADF - the _socket_ argument is not a valid file descriptor
|
|
* * Errno::EDESTADDRREQ - the _socket_ is not bound to a local address, and
|
|
* the protocol does not support listening on an unbound socket
|
|
* * Errno::EINVAL - the _socket_ is already connected
|
|
* * Errno::ENOTSOCK - the _socket_ argument does not refer to a socket
|
|
* * Errno::EOPNOTSUPP - the _socket_ protocol does not support listen
|
|
* * Errno::EACCES - the calling process does not have approriate privileges
|
|
* * Errno::EINVAL - the _socket_ has been shut down
|
|
* * Errno::ENOBUFS - insufficient resources are available in the system to
|
|
* complete the call
|
|
*
|
|
* === Windows Exceptions
|
|
* On Windows systems the following system exceptions may be raised if
|
|
* the call to _listen_ fails:
|
|
* * Errno::ENETDOWN - the network is down
|
|
* * Errno::EADDRINUSE - the socket's local address is already in use. This
|
|
* usually occurs during the execution of _bind_ but could be delayed
|
|
* if the call to _bind_ was to a partially wildcard address (involving
|
|
* ADDR_ANY) and if a specific address needs to be commmitted at the
|
|
* time of the call to _listen_
|
|
* * Errno::EINPROGRESS - a Windows Sockets 1.1 call is in progress or the
|
|
* service provider is still processing a callback function
|
|
* * Errno::EINVAL - the +socket+ has not been bound with a call to _bind_.
|
|
* * Errno::EISCONN - the +socket+ is already connected
|
|
* * Errno::EMFILE - no more socket descriptors are available
|
|
* * Errno::ENOBUFS - no buffer space is available
|
|
* * Errno::ENOTSOC - +socket+ is not a socket
|
|
* * Errno::EOPNOTSUPP - the referenced +socket+ is not a type that supports
|

|
* out-of-band-data
|
|
* * Errno::EWOULDBLOCK - see Errno::EAGAIN
|
|
* * Errno::EBADF - the +socket+ is not a valid file descriptor
|
|
* * Errno::ECONNRESET - a connection was forcibly closed by a peer
|
|
* * Errno::EFAULT - the socket's internal buffer, address or address length
|
|
* cannot be accessed or written
|
|
* * Errno::EINTR - a signal interupted _recvfrom_ before any data was available
|
|
* * Errno::EINVAL - the MSG_OOB flag is set and no out-of-band data is available
|
|
* * Errno::EIO - an i/o error occurred while reading from or writing to the
|
|
* filesystem
|
|
* * Errno::ENOBUFS - insufficient resources were available in the system to
|
|
* perform the operation
|
|
* * Errno::ENOMEM - insufficient memory was available to fulfill the request
|
|
* * Errno::ENOSR - there were insufficient STREAMS resources available to
|
|
* complete the operation
|
|
* * Errno::ENOTCONN - a receive is attempted on a connection-mode socket that
|
|
* is not connected
|
|
* * 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
|
|
* or due to a transmission timeout on an active connection
|
|
*
|
|
* === 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 accomodate 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 connetion
|
|
* 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
|
|
* message.

|
|
* 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 but at the
|
|
* expense of greater complexity. In particular, the class handles addresses
|
|
* using +struct+ sockaddr structures packed into Ruby strings, which can be
|
|
* a joy to manipulate.
|
|
*
|
|
* === Exception Handling
|
|
* Ruby's implementation of +Socket+ causes an exception to be raised
|
|
* 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.
