一个CAsyncSocket扩展类的例子。 实现了从指定的服务器和端口获得TCP数据流。不过现在可能程序中指定的服务器已经关闭了，不过代码还是可以看看的。-An example of CAsyncSocket extended class implements the function to get TCP data stream from a dedicated server and port.Perhaps,the server using in code has been closed,but the code has some value to view.

IFO is an acronym for First In, First Out, an abstraction in ways of organizing and manipulation of data relative to time and prioritization.
