Returns the names of all available ciphers in an array.
returns the socket option name as an integer.
p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).optname #=> 2
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]
Convert 64-bit FILETIME integer into Time object.
returns array of WIN32OLE_PARAM object corresponding with method parameters.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE_METHOD.new(tobj, 'SaveAs')
p method.params # => [Filename, FileFormat, Password, WriteResPassword,

Changes the parameters of the deflate stream to allow changes between different types of data that require different types of compression. Any unprocessed data is flushed before changing the params.
See Zlib::Deflate.new for a description of level and strategy.
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 (x).
op can be a mathematical operation such as +, -, *, /
A set of tasks to prepare the file in order to parse it
Returns the headers for this row:
source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n" table = CSV.parse(source, headers: true) row = table.first row.headers # => ["Name", "Value"]
Returns a new Array containing the String headers for the table.
If the table is not empty, returns the headers from the first row:
rows = [ CSV::Row.new(['Foo', 'Bar'], []), CSV::Row.new(['FOO', 'BAR'], []), CSV::Row.new(['foo', 'bar'], []), ] table = CSV::Table.new(rows) table.headers # => ["Foo", "Bar"] table.delete(0) table.headers # => ["FOO", "BAR"] table.delete(0) table.headers # => ["foo", "bar"]
If the table is empty, returns a copy of the headers in the table itself:
table.delete(0) table.headers # => ["Foo", "Bar"]
