Lua练习21-lua的协程

co2 = coroutine.create(
    function()
        for i=1,10 do
            print(i)
            if i == 3 then
                print(coroutine.status(co2))  --running
                print(coroutine.running()) --thread:XXXXXX
            end
            coroutine.yield()
        end
    end
)
 
coroutine.resume(co2) --1
coroutine.resume(co2) --2
coroutine.resume(co2) --3
 
print(coroutine.status(co2))   -- suspended
print(coroutine.running())
 
print("----------")

结果：
