- * call-seq:
- * 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.
- * If _maxlen_ is omitted, its default value is 65536.
- * _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
- * begin # emulate blocking recvfrom
- * p s2.recvfrom_nonblock(10) #=> ["aaa", ["AF_INET", 33302, "localhost.localdomain", "127.0.0.1"]]
- * rescue IO::WaitReadable
- * IO.select([s2])
- * retry
- * end
- *
- * 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.
- *
- * 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 recvfrom_nonblock.
- *
