Returns a new instance of OpenSSL::Digest by name.
Will raise an EngineError if the digest is unavailable.
e = OpenSSL::Engine.by_id("openssl") #=> #<OpenSSL::Engine id="openssl" name="Software engine support"> e.digest("SHA1") #=> #<OpenSSL::Digest: da39a3ee5e6b4b0d3255bfef95601890afd80709> e.digest("zomg") #=> OpenSSL::Engine::EngineError: no such digest `zomg'
Pretty prints this engine.
Get the indentation level.
Set the indentation level to level. The level must be less than 10 and greater than 1.
Returns the exit status of the child for which PTY#check raised this exception
The line number of the current token. This value starts from 1. This method is valid only in event handlers.
The scanner’s state of the current token. This value is the bitwise OR of zero or more of the Ripper::EXPR_* constants.
returns a string which shows ancillarydata in human-readable form.
p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").inspect #=> "#<Socket::AncillaryData: INET6 IPV6 PKTINFO \"\">"
Creates a new Socket::AncillaryData object which contains a int as data.
The size and endian is dependent on the host.
require 'socket' p Socket::AncillaryData.int(:UNIX, :SOCKET, :RIGHTS, STDERR.fileno) #=> #<Socket::AncillaryData: UNIX SOCKET RIGHTS 2>
Returns the data in ancillarydata as an int.
The size and endian is dependent on the host.
ancdata = Socket::AncillaryData.int(:UNIX, :SOCKET, :RIGHTS, STDERR.fileno) p ancdata.int #=> 2
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

}
Returns a string to show contents of ifaddr.
Returns the interface index of ifaddr.
Returns the destination address of ifaddr. nil is returned if the flags doesn’t have IFF_POINTOPOINT.
Returns a string which shows sockopt in human-readable form.
p Socket::Option.new(:INET, :SOCKET, :KEEPALIVE, [1].pack("i")).inspect #=> "#<Socket::Option: INET SOCKET KEEPALIVE 1>"
Creates a new Socket::Option object which contains an int as data.
The size and endian is dependent on the platform.
p Socket::Option.int(:INET, :SOCKET, :KEEPALIVE, 1) #=> #<Socket::Option: INET SOCKET KEEPALIVE 1>
Returns the data in sockopt as an int.
The size and endian is dependent on the platform.
sockopt = Socket::Option.int(:INET, :SOCKET, :KEEPALIVE, 1) p sockopt.int => 1
Write data to a registry value named name. When name is nil, write to the ‘default’ value.
type is type value. (see Registry::Constants module) Class of data must be same as which read method returns.
Write value to a registry value named name.
The value type is REG_SZ(write_s), REG_DWORD(write_i), or REG_BINARY(write_bin).
Write value to a registry value named name.
The value type is REG_SZ(write_s), REG_DWORD(write_i), or REG_BINARY(write_bin).
Returns key information as Array of: :num_keys
The number of subkeys.
:max_key_length

:num_values
The number of values.
:max_value_name_length
