* 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 {
|
|
* 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").hton +
|
|
* IPAddr.new(Socket::INADDR_ANY, Socket::AF_INET).hton
|
|
* 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
|
|
* * +options+ - keyword hash, supporting `exception: false`
|
|
*
|
|
* === 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
|
|
* begin # emulate blocking recv.
|
|
* p s.recv_nonblock(10) #=> "aaa"
|
|
* rescue IO::WaitReadable
|
|
* IO.select([s])
|
|
* retry
|
|
* end
|
|
*
|
|
* 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.
|
|
*
|
|
* If the exception is Errno::EWOULDBLOCK or Errno::AGAIN,
|
|
* it is extended by IO::WaitReadable.
|
|
* So IO::WaitReadable can be used to rescue the exceptions for retrying recv_nonblock.
|
|
*
|
|
* By specifying `exception: false`, the options hash allows you to indicate
|
|
* that recv_nonblock should not raise an IO::WaitWritable exception, but
|
|
* return the symbol :wait_writable instead.
