Extracts addr and ifindex from IPV6_PKTINFO ancillary data.
IPV6_PKTINFO is defined by RFC 3542.
addr = Addrinfo.ip("::1") ifindex = 0 ancdata = Socket::AncillaryData.ipv6_pktinfo(addr, ifindex) p ancdata.ipv6_pktinfo #=> [#<Addrinfo: ::1>, 0]
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 variable kind string.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType')
variables = tobj.variables
variables.each do |variable|
puts "#{variable.name} #{variable.variable_kind}"
end
The result of above script is following:
xlChart CONSTANT
xlDialogSheet CONSTANT
xlExcel4IntlMacroSheet CONSTANT
xlExcel4MacroSheet CONSTANT
xlWorksheet CONSTANT
Returns original filename recorded in the gzip file header, or nil if original filename is not present.
Specify the original name (str) in the gzip header.
Returns true if stat is writable by the real user id of this process.
File.stat("testfile").writable_real? #=> true
If stat is writable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).
m = File.stat("/tmp").world_writable? #=> 511 sprintf("%o", m) #=> "777"
Returns the number of the first source line where the instruction sequence was loaded from.
For example, using irb:
iseq = RubyVM::InstructionSequence.compile('num = 1 + 2') #=> <RubyVM::InstructionSequence:<compiled>@<compiled>> iseq.first_lineno #=> 1
Return trace points in the instruction sequence. Return an array of [line, event_symbol] pair.
Stop this server.
Like Net::HTTP.get, but writes the returned body to $stdout; returns nil.
Posts data to a host; returns a Net::HTTPResponse object.
Argument url must be a URI; argument data must be a hash:
_uri = uri.dup _uri.path = '/posts' data = {title: 'foo', body: 'bar', userId: 1} res = Net::HTTP.post_form(_uri, data) # => #<Net::HTTPCreated 201 Created readbody=true> puts res.body
Output:
{
"title": "foo",
"body": "bar",
"userId": "1",
"id": 101
}
