coroutine.wrap
Lua function coroutine.wrap Summary Creates a thread and returns a function to resume it Prototype `f = coroutine.wrap (f)` Description `Creates a thread with body f, and then returns a function that can be used to resume the thread. This is a slightly simpler interface than the coroutine.create / coroutine.resume sequence, however it makes error management harder.
    function f (s)
      print ("Entering f with value", s)
      v = coroutine.yield ()
      print ("After yield, v is", v)
      return 22
    end -- f

    resumer = coroutine.wrap (f)
    resumer (88)  -- start thread
    resumer (99)  -- resume after yield

     -->

    Entering f with value 88
    After yield, v is 99
