Socket,CAsyncSocket,CSocket介绍
Socket有同步阻塞方式和异步非阻塞方式两种使用,事实上同步和异步在我们编程的生涯中可能遇到了很多,而Socket也没什么特别。虽然同步好用,不费劲,但不能满足一些应用场合,其效率也很低。
也许初涉编程的人不能理解"同步(或阻塞)"和"异步(或非阻塞)",其实简单两句话就能讲清楚,同步和异步往往都是针对一个函数来说的,"同步"就是函数直到其要执行的功能全部完成时才返回,而"异步"则是,函数仅仅做一些简单的工作,然后马上返回,而它所要实现的功能留给别的线程或者函数去完成。例如,SendMessage就是"同步"函数,它不但发送消息到消息队列,还需要等待消息被执行完才返回;相反PostMessage就是个异步函数,它只管发送一个消息,而不管这个消息是否被处理,就马上返回。(SocketCAsyncSocketCSocket)
