Disallows further read using shutdown system call.

s1, s2 = UNIXSocket.pair
s1.close_read
s2.puts #=> Broken pipe (Errno::EPIPE)

Returns an Addrinfo object for local address obtained by getsockname.

Note that addrinfo.protocol is filled by 0.

TCPSocket.open("www.ruby-lang.org", 80) {|s|
  p s.local_address #=> #<Addrinfo: 192.168.0.129:36873 TCP>
}

TCPServer.open("127.0.0.1", 1512) {|serv|
  p serv.local_address #=> #<Addrinfo: 127.0.0.1:1512 TCP>
}

Returns the IP address as a string.

Addrinfo.tcp("127.0.0.1", 80).ip_address    #=> "127.0.0.1"
Addrinfo.tcp("::1", 80).ip_address          #=> "::1"

Example

UNIXServer.open("/tmp/sock") {|serv|
  UNIXSocket.open("/tmp/sock") {|c|
    s = serv.accept

    c.send_io STDOUT
    stdout = s.recv_io

    p STDOUT.fileno #=> 1
    p stdout.fileno #=> 7

    stdout.puts "hello" # outputs "hello\n" to standard output.
  }
}

klass will determine the class of io returned (using the IO.for_fd singleton method or similar). If klass is nil, an integer file descriptor is returned.

mode is the same as the argument passed to IO.for_fd

Closes the read end of a StringIO. Will raise an IOError if the receiver is not readable.

Returns true if the stream is not readable, false otherwise.

Returns the pre-match

s = StringScanner.new('test string')
s.scan(/\w+/)           # -> "test"
s.scan(/\s+/)           # -> " "
s.pre_match             # -> "test"
s.post_match            # -> "string"

Invokes Release method of Dispatch interface of WIN32OLE object. You should not use this method because this method exists only for debugging WIN32OLE. The return value is reference counter of OLE object.

Creates GUID.

WIN32OLE.create_guid # => {1CB530F1-F6B1-404D-BCE6-1959BF91F4A8}

invokes Release method of Dispatch interface of WIN32OLE object. Usually, you do not need to call this method because Release method called automatically when WIN32OLE object garbaged.

removes the callback of event.

ie = WIN32OLE.new('InternetExplorer.Application')
ev = WIN32OLE_EVENT.new(ie)
ev.on_event('BeforeNavigate2') {|*args|
  args.last[6] = true
}
  ...
ev.off_event('BeforeNavigate2')
  ...

Returns string of return value type of method.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbooks')
method = WIN32OLE_METHOD.new(tobj, 'Add')
puts method.return_type # => Workbook

Returns number of return value type of method.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbooks')
method = WIN32OLE_METHOD.new(tobj, 'Add')
puts method.return_vtype # => 26

Returns event interface name if the method is event.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE_METHOD.new(tobj, 'SheetActivate')
puts method.event_interface # =>  WorkbookEvents

Returns the file extension appended to the names of modified files under in-place edit mode. This value can be set using ARGF.inplace_mode= or passing the -i switch to the Ruby binary.

Sets the filename extension for in-place editing mode to the given String. Each file being edited has this value appended to its filename. The modified file is saved under this new name.

For example:

$ ruby argf.rb file.txt

ARGF.inplace_mode = '.bak'
ARGF.each_line do |line|
  print line.sub("foo","bar")
end

Each line of file.txt has the first occurrence of “foo” replaced with “bar”, then the new line is written out to file.txt.bak.

Returns true if headers will be returned as a row of results. See CSV::new for details.

Returns the list of break points where execution will be stopped.

See DEBUGGER__ for more usage

Returns a new binding each time near TOPLEVEL_BINDING for runs that do not specify a binding.

Create unnamed module, define methodname as instance method of it, and return it.

example:

filename = 'example.rhtml'   # 'arg1' and 'arg2' are used in example.rhtml
erb = ERB.new(File.read(filename))
erb.filename = filename
MyModule = erb.def_module('render(arg1, arg2)')
class MyClass
  include MyModule
end
