对例子的自我理解:

--  协程的理解
-- co 是协程的内容,类似函数内容, 通过yield 将中止函数的操作,
-- 但重新resume后,将继续执行co未执行到内容 function foo(a)
print("foo", a)
return coroutine.yield( * a)
end co = coroutine.create(function ( a, b )
print("co-body", a, b)
local r = foo(a + )
print("co-body", r)
local r, s = coroutine.yield(a + b, a - b)
print("co-body", r, s)
return b, "end"
end) -- resume首次传递参数 yield 返回true 与 yield的参数
local c, d = coroutine.resume(co, , )
print("main:", c, d)
print("main", coroutine.resume(co, "r"))
print("main", coroutine.resume(co, "x", "y"))
print("main", coroutine.resume(co, "x", "y")) -- 执行结果
-- co-body 1 10
-- foo 2
-- main true 4 -- co-body r
-- main true 11 -9 -- co-body x y
-- main true 10 end -- main false cannot resume dead coroutine

lua协程是协作式多任务,用于异步通信的机制,参考链接:
