Waits until IO is readable without blocking and returns self, or nil when times out. Returns true immediately when buffered data is available.

Closes the read end of a duplex I/O stream (i.e., one that contains both a read and a write stream, such as a pipe). Will raise an IOError if the stream is not duplexed.

f = IO.popen("/bin/sh","r+")
f.close_read
f.readlines

produces:

prog.rb:3:in `readlines': not opened for reading (IOError)
 from prog.rb:3

Returns a hash representing information about named captures of rxp.

A key of the hash is a name of the named captures. A value of the hash is an array which is list of indexes of corresponding named captures.

/(?<foo>.)(?<bar>.)/.named_captures
#=> {"foo"=>[1], "bar"=>[2]}

/(?<foo>.)(?<foo>.)/.named_captures
#=> {"foo"=>[1, 2]}

If there are no named captures, an empty hash is returned.

/(.)(.)/.named_captures
#=> {}

See FileTest.world_readable?.

See FileTest.writable_real?.

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 strio is not readable.

Returns true if strio is not readable, false otherwise.

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

This method is an encoding safe version of Regexp::escape(). It will escape any characters that would change the meaning of a regular expression in the encoding of str. Regular expression characters that cannot be transcoded to the target encoding will be skipped and no escaping will be performed if a backslash cannot be transcoded.

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