Returns the exit status of the child for which PTY#check raised this exception

Another entry point for the parser. If you use this method, you must implement RECEIVER#METHOD_ID method.

RECEIVER#METHOD_ID is a method to get next token. It must ‘yield’ the token, which format is [TOKEN-SYMBOL, VALUE].

Starts the parser. init is a data accumulator and is passed to the next event handler (as of Enumerable#inject).

returns the socket family as an integer.

p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").family
#=> 10

returns the cmsg data as a string.

p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").data
#=> ""

returns the socket family as an integer.

p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).family
#=> 10

returns the socket option data as a string.

p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).data
#=> "\x01\x00\x00\x00"

Calls String#unpack on sockopt.data.

sockopt = Socket::Option.new(:INET, :SOCKET, :KEEPALIVE, [1].pack("i"))
p sockopt.unpack("i")      #=> [1]
p sockopt.data.unpack("i") #=> [1]

Logs a message at the fatal (syslog err) log level, or logs the message returned from the block.

Compresses the given string. Valid values of level are Zlib::NO_COMPRESSION, Zlib::BEST_SPEED, Zlib::BEST_COMPRESSION, Zlib::DEFAULT_COMPRESSION, or an integer from 0 to 9.

This method is almost equivalent to the following code:

def deflate(string, level)
  z = Zlib::Deflate.new(level)
  dst = z.deflate(string, Zlib::FINISH)
  z.close
  dst
end

See also Zlib.inflate

Inputs string into the deflate stream and returns the output from the stream. On calling this method, both the input and the output buffers of the stream are flushed. If string is nil, this method finishes the stream, just like Zlib::ZStream#finish.

If a block is given consecutive deflated chunks from the string are yielded to the block and nil is returned.

The flush parameter specifies the flush mode. The following constants may be used:

Zlib::NO_FLUSH

The default

Zlib::SYNC_FLUSH

Flushes the output to a byte boundary

Zlib::FULL_FLUSH

SYNC_FLUSH + resets the compression state

Zlib::FINISH

Pending input is processed, pending output is flushed.

See the constants for further description.

Decompresses string. Raises a Zlib::NeedDict exception if a preset dictionary is needed for decompression.

This method is almost equivalent to the following code:

def inflate(string)
  zstream = Zlib::Inflate.new
  buf = zstream.inflate(string)
  zstream.finish
  zstream.close
  buf
end

See also Zlib.deflate

Inputs deflate_string into the inflate stream and returns the output from the stream. Calling this method, both the input and the output buffer of the stream are flushed. If string is nil, this method finishes the stream, just like Zlib::ZStream#finish.

If a block is given consecutive inflated chunks from the deflate_string are yielded to the block and nil is returned.

Raises a Zlib::NeedDict exception if a preset dictionary is needed to decompress. Set the dictionary by Zlib::Inflate#set_dictionary and then call this method again with an empty string to flush the stream:

inflater = Zlib::Inflate.new

begin
  out = inflater.inflate compressed
rescue Zlib::NeedDict
  # ensure the dictionary matches the stream's required dictionary
  raise unless inflater.adler == Zlib.adler32(dictionary)

  inflater.set_dictionary dictionary
  inflater.inflate ''
end

# ...

inflater.close

Returns last modification time recorded in the gzip file header.

Returns comments recorded in the gzip file header, or nil if the comments is not present.

Specify the modification time (mtime) in the gzip header. Using a Fixnum or Integer

Specify the comment (str) in the gzip header.

Reads at most maxlen bytes from the gziped stream but it blocks only if gzipreader has no data immediately available. If the optional outbuf argument is present, it must reference a String, which will receive the data. It raises EOFError on end of file.

Returns the modification time of stat.

File.stat("testfile").mtime   #=> Wed Apr 09 08:53:14 CDT 2003

Returns the change time for stat (that is, the time directory information about the file was changed, not the file itself).

Note that on Windows (NTFS), returns creation time (birth time).

File.stat("testfile").ctime   #=> Wed Apr 09 08:53:14 CDT 2003

Returns true if key is registered

Returns the contents of this Tms object as a formatted string, according to a format string like that passed to Kernel.format. In addition, format accepts the following extensions:

%u

Replaced by the user CPU time, as reported by Tms#utime.

%y

Replaced by the system CPU time, as reported by stime (Mnemonic: y of “s*y*stem”)

%U

Replaced by the children’s user CPU time, as reported by Tms#cutime

%Y

Replaced by the children’s system CPU time, as reported by Tms#cstime

%t

Replaced by the total CPU time, as reported by Tms#total

%r

Replaced by the elapsed real time, as reported by Tms#real

%n

Replaced by the label string, as reported by Tms#label (Mnemonic: n of “*n*ame”)

If format is not given, FORMAT is used as default value, detailing the user, system and real elapsed time.

Returns a new Tms object obtained by memberwise operation op of the individual times for this Tms object with those of the other Tms object.

op can be a mathematical operation such as +, -, *, /
