An OpenSSL::OCSP::CertificateId identifies a certificate to the CA so that a status check can be performed.

IO wrapper that creates digests of contents written to the IO it wraps.

Passwd is a placeholder Struct for user database on Unix systems.

The struct contains the following members

name

contains the short login name of the user as a String.

passwd

contains the encrypted password of the user as a String. an 'x' is returned if shadow passwords are in use. An '*' is returned if the user cannot log in using a password.

uid

contains the integer user ID (uid) of the user.

gid

contains the integer group ID (gid) of the user’s primary group.

dir

contains the path to the home directory of the user as a String.

shell

contains the path to the login shell of the user as a String.

The following members below are system-dependent

gecos

contains a longer String description of the user, such as a full name. Some Unix systems provide structured information in the gecos field, but this is system-dependent.

change

password change time(integer).

quota

quota value(integer).

age

password age(integer).

class

user access class(string).

comment

comment(string).

expire

account expiration time(integer).

Cleared reference exception

Used internally by Fiddle::Importer

Wrapper for arrays within a struct

The base exception for JSON errors.

This exception is raised if the required unicode support is missing on the system. Usually this means that the iconv library is not installed.

Configuration for the openssl library.

Many system’s installation of openssl library will depend on your system configuration. See the value of OpenSSL::Config::DEFAULT_CONFIG_FILE for the location of the file for your host.

See also www.openssl.org/docs/apps/config.html

General error for openssl library configuration files. Including formatting, parsing errors, etc.

Scan scalars for built in types

Thrown when PTY::check is called for a pid that represents a process that has exited.

Socket::AncillaryData represents the ancillary data (control information) used by sendmsg and recvmsg system call. It contains socket family, control message (cmsg) level, cmsg type and cmsg data.

OLEProperty is a helper class of Property with arguments, used by olegen.rb-generated files.

WIN32OLE::Variable objects represent OLE variable information.

WIN32OLE::Variant objects represents OLE variant.

Win32OLE converts Ruby object into OLE variant automatically when invoking OLE methods. If OLE method requires the argument which is different from the variant by automatic conversion of Win32OLE, you can convert the specified variant type by using WIN32OLE::Variant class.

param = WIN32OLE::Variant.new(10, WIN32OLE::VARIANT::VT_R4)
oleobj.method(param)

WIN32OLE::Variant does not support VT_RECORD variant. Use WIN32OLE::Record class instead of WIN32OLE::Variant if the VT_RECORD variant is needed.

Zlib::GzipWriter is a class for writing gzipped files. GzipWriter should be used with an instance of IO, or IO-like, object.

Following two example generate the same result.

Zlib::GzipWriter.open('hoge.gz') do |gz|
  gz.write 'jugemu jugemu gokou no surikire...'
end

File.open('hoge.gz', 'w') do |f|
  gz = Zlib::GzipWriter.new(f)
  gz.write 'jugemu jugemu gokou no surikire...'
  gz.close
end

To make like gzip(1) does, run following:

orig = 'hoge.txt'
Zlib::GzipWriter.open('hoge.gz') do |gz|
  gz.mtime = File.mtime(orig)
  gz.orig_name = orig
  gz.write IO.binread(orig)
end

NOTE: Due to the limitation of Ruby’s finalizer, you must explicitly close GzipWriter objects by Zlib::GzipWriter#close etc. Otherwise, GzipWriter will be not able to write the gzip footer and will generate a broken gzip file.
