Lua编程示例（七）：协同程序基础逻辑
co=coroutine.create(function()
print("hi")
end)
print(coroutine.status(co))
coroutine.resume(co)
print(coroutine.status(co))
print()
co=coroutine.create(function()
fori=1,2do
print("co",i)
coroutine.yield()
end
end)
coroutine.resume(co)
print(coroutine.status(co))
coroutine.resume(co)
print(coroutine.status(co))
coroutine.resume(co)--没有输出
print(coroutine.status(co))
print()
co=coroutine.create(function(a,b,c)
print("co",a,b,c)
end)
coroutine.resume(co,1,2,3)
co=coroutine.create(function(a,b)
print("I'mbeforeyield")--第一次运行执行
coroutine.yield(a+b,a-b,"needlessargs")--在这停住,返回yield的参数
print("Mgs")
end)
print(coroutine.resume(co,20,10))--参数传给yield,处理后再返回
print("Iprintfirst")
coroutine.resume(co)
co=coroutine.create(function()
return"I'llreturn"
end)
print(coroutine.resume(co))--主函数的返回值回传给resume
print()
输出结果：
