这是一个Tcp协议的网络引擎，包括两个部分： a、服务器采用完成端口模型，提供了丰富的接口函数 b、客户端采用三线程加重叠Io模型，速度快，稳定 都采用回调函数接收数据，是对网络Tcp模型Socket的完整封装，所有代码在Windows2000下测试通过，并已应用到很多现有的中型网络系统中。-This a remarkably agreement Network engines, including two parts : a server used to complete port model, a rich interface function b, client using three overlapping threads increases Io model, speed and stability using a callback function to receive information, the network model DEC Socket complete package, all of the code in the test under Windows 2000, and has been applied to many existing medium-sized network systems.
