=begin
(({time()})) returns (({time_t})), not pointer.
As Fiddle doesn't provide (({TYPE_TIME_T})) currently, you have to use (({TYPE_LONG})) instead.

require 'fiddle'
libc = Fiddle.dlopen(nil)
time = Fiddle::Function.new(libc['time'], [Fiddle::TYPE_VOIDP], Fiddle::TYPE_LONG)
puts time.call(nil)
=end
