回答1:
Yes, it's possible with FFI for example.
At first, you should install ffi
gem:
gem install ffi
And then attach this function:
require 'ffi'
module Foo
extend FFI::Library
ffi_lib "kernel32.dll"
ffi_convention :stdcall
attach_function :get_tick_count, :GetTickCount, [ ], :int
end
puts Foo.get_tick_count #=> 107073812

use windows api:
require 'Win32API'
t = Win32API.new("kernel32", "GetTickCount", nil, 'L')
t.call()
or Time.now - t.call() / 1000.0
to get a time when machine was booted
