• mac_iter - integer

• keytype - An integer representing an MSIE specific extension.

Any optional arguments may be supplied as nil to preserve the OpenSSL defaults.

See the OpenSSL documentation for PKCS12_create().

Convert path string to a class

returns the timestamp as a time object.

ancillarydata should be one of following type:

• SOL_SOCKET/SCM_TIMESTAMP (microsecond) GNU/Linux, FreeBSD, NetBSD, OpenBSD, Solaris, MacOS X

• SOL_SOCKET/SCM_TIMESTAMPNS (nanosecond) GNU/Linux

• SOL_SOCKET/SCM_BINTIME (2**(-64) second) FreeBSD

  Addrinfo.udp(“127.0.0.1”, 0).bind {|s1|

    s2.send "a", 0, s1.local_address

    t = ctl.timestamp
    p t      #=> 2009-02-24 17:35:46 +0900

    p t.nsec #=> 775581000

Returns the broadcast address of ifaddr. nil is returned if the flags doesn’t have IFF_BROADCAST.

Returns the destination address of ifaddr. nil is returned if the flags doesn’t have IFF_POINTOPOINT.

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 the last access time for this file as an object of class Time.

File.stat("testfile").atime   #=> Wed Dec 31 18:00:00 CST 1969

Returns true if stat is readable by the effective user id of this process.

File.stat("testfile").readable?   #=> true

Returns true if stat is writable by the effective user id of this process.

File.stat("testfile").writable?   #=> true

Returns true if stat is executable or if the operating system doesn’t distinguish executable files from nonexecutable files. The tests are made using the effective owner of the process.

File.stat("testfile").executable?   #=> false

Returns the path of this instruction sequence.

<compiled> if the iseq was evaluated from a string.

For example, using irb:

iseq = RubyVM::InstructionSequence.compile('num = 1 + 2')
#=> <RubyVM::InstructionSequence:<compiled>@<compiled>>
iseq.path
#=> "<compiled>"

Using ::compile_file:

# /tmp/method.rb
def hello
  puts "hello, world"
end

# in irb
> iseq = RubyVM::InstructionSequence.compile_file('/tmp/method.rb')
> iseq.path #=> /tmp/method.rb
