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
Logs a message
at the info (syslog info) log level, or logs the message returned from the block.
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
Maximum length of name of subkeys.
:num_values
The number of values.
:max_value_name_length
Maximum length of name of values.
:max_value_length
Maximum length of value of values.
:descriptor_length
Length of security descriptor.
:wtime
Last write time as FILETIME(64-bit integer)

Returns true if the stream is finished.
Finishes the stream and flushes output buffer. If a block is given each chunk is yielded to the block until the input buffer has been flushed to the output buffer.
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.
If a :buffer keyword argument is given and not nil:
The :buffer keyword should be a String
, and will used as the output buffer. Using this option can reuse the memory required during inflation.
When not passing a block, the return value will be the same object as the :buffer keyword argument.
When passing a block, the yielded chunks will be the same value as the :buffer keyword argument.
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

Closes the GzipFile
object. Unlike Zlib::GzipFile#close
, this method never calls the close method of the associated IO
object. Returns the associated IO
object.
Same as IO
.
The line number of the last row read from this file.
Specify line number of the last row read from this file.
Resets the position of the file pointer to the point created the GzipReader
object. The associated IO
object needs to respond to the seek
method.
