This method is called when a parse error is found.

ERROR_TOKEN_ID is an internal ID of token which caused error. You can get string representation of this ID by calling token_to_str.

ERROR_VALUE is a value of error token.

value_stack is a stack of symbol values. DO NOT MODIFY this object.

This method raises ParseError by default.

If this method returns, parsers enter “error recovering mode”.

Creates a new Socket::AncillaryData object which contains file descriptors as data.

p Socket::AncillaryData.unix_rights(STDERR)
#=> #<Socket::AncillaryData: UNIX SOCKET RIGHTS 2>

returns the array of IO objects for SCM_RIGHTS control message in UNIX domain socket.

The class of the IO objects in the array is IO or Socket.

The array is attached to ancillarydata when it is instantiated. For example, BasicSocket#recvmsg attach the array when receives a SCM_RIGHTS control message and :scm_rights=>true option is given.

# recvmsg needs :scm_rights=>true for unix_rights
s1, s2 = UNIXSocket.pair
p s1                                         #=> #<UNIXSocket:fd 3>
s1.sendmsg "stdin and a socket", 0, nil, Socket::AncillaryData.unix_rights(STDIN, s1)
_, _, _, ctl = s2.recvmsg(:scm_rights=>true)
p ctl                                        #=> #<Socket::AncillaryData: UNIX SOCKET RIGHTS 6 7>
p ctl.unix_rights                            #=> [#<IO:fd 6>, #<Socket:fd 7>]
p File.identical?(STDIN, ctl.unix_rights[0]) #=> true
p File.identical?(s1, ctl.unix_rights[1])    #=> true

# If :scm_rights=>true is not given, unix_rights returns nil
s1, s2 = UNIXSocket.pair
s1.sendmsg "stdin and a socket", 0, nil, Socket::AncillaryData.unix_rights(STDIN, s1)
_, _, _, ctl = s2.recvmsg
p ctl #=> #<Socket::AncillaryData: UNIX SOCKET RIGHTS 6 7>
p ctl.unix_rights #=> nil

Returns new ancillary data for IP_PKTINFO.

If spec_dst is not given, addr is used.

IP_PKTINFO is not standard.

Supported platform: GNU/Linux

addr = Addrinfo.ip("127.0.0.1")
ifindex = 0
spec_dst = Addrinfo.ip("127.0.0.1")
p Socket::AncillaryData.ip_pktinfo(addr, ifindex, spec_dst)
#=> #<Socket::AncillaryData: INET IP PKTINFO 127.0.0.1 ifindex:0 spec_dst:127.0.0.1>

Extracts addr, ifindex and spec_dst from IP_PKTINFO ancillary data.

IP_PKTINFO is not standard.

Supported platform: GNU/Linux

addr = Addrinfo.ip("127.0.0.1")
ifindex = 0
spec_dest = Addrinfo.ip("127.0.0.1")
ancdata = Socket::AncillaryData.ip_pktinfo(addr, ifindex, spec_dest)
p ancdata.ip_pktinfo
#=> [#<Addrinfo: 127.0.0.1>, 0, #<Addrinfo: 127.0.0.1>]

Returns new ancillary data for IPV6_PKTINFO.

IPV6_PKTINFO is defined by RFC 3542.

addr = Addrinfo.ip("::1")
ifindex = 0
p Socket::AncillaryData.ipv6_pktinfo(addr, ifindex)
#=> #<Socket::AncillaryData: INET6 IPV6 PKTINFO ::1 ifindex:0>

Extracts addr and ifindex from IPV6_PKTINFO ancillary data.

IPV6_PKTINFO is defined by RFC 3542.

addr = Addrinfo.ip("::1")
ifindex = 0
ancdata = Socket::AncillaryData.ipv6_pktinfo(addr, ifindex)
p ancdata.ipv6_pktinfo #=> [#<Addrinfo: ::1>, 0]

Replace %w+% into the environment value of what is contained between the %‘s This method is used for REG_EXPAND_SZ.

For detail, see expandEnvironmentStrings Win32 API.

Defines the callback event. If argument is omitted, this method defines the callback of all events. If you want to modify reference argument in callback, return hash in callback. If you want to return value to OLE server as result of callback use ‘return’ or :return.

ie = WIN32OLE.new('InternetExplorer.Application')
ev = WIN32OLE_EVENT.new(ie)
ev.on_event("NavigateComplete") {|url| puts url}
ev.on_event() {|ev, *args| puts "#{ev} fired"}

ev.on_event("BeforeNavigate2") {|*args|
  ...
  # set true to BeforeNavigate reference argument `Cancel'.
  # Cancel is 7-th argument of BeforeNavigate,
  # so you can use 6 as key of hash instead of 'Cancel'.
  # The argument is counted from 0.
  # The hash key of 0 means first argument.)
  {:Cancel => true}  # or {'Cancel' => true} or {6 => true}
}

ev.on_event(...) {|*args|
  {:return => 1, :xxx => yyy}
}

Duplicates the deflate stream.

What is this?

:)

Same as IO.

Make an internal copy of the source buffer. Updates to the copy will not affect the source buffer.

source = IO::Buffer.for("Hello World")
# =>
# #<IO::Buffer 0x00007fd598466830+11 EXTERNAL READONLY SLICE>
# 0x00000000  48 65 6c 6c 6f 20 57 6f 72 6c 64                Hello World
buffer = source.dup
# =>
# #<IO::Buffer 0x0000558cbec03320+11 INTERNAL>
# 0x00000000  48 65 6c 6c 6f 20 57 6f 72 6c 64                Hello World

Calls superclass method.
