sendto函数用于在套接字上写入传出数据。 对于面向消息的套接字,必须注意不要超过基础子网的最大数据包大小,这可以通过使用getsockopt检索套接字选项的值SO_MAX_MSG_SIZE获得。 如果数据太长,无法通过基础协议以原子方式传递,则会返回错误WSAEMSGSIZE,并且不会传输任何数据。

它是一个NSObject的Category,只要你对强转成遵从<vk_msgsend>的id对象,就能直接调用 它像performSelector一样输入SEL做参数执行,但是传参非常容易,基础类型,struct都支持,不需要withObject,不需要转成id,只需要像NSLog()一样,按顺序输入可变参数就好。
