摘　要:介绍了Ｗｉｎ32平台(Ｗｉｎｄｏｗｓ95/98/ＮＴ)下ｓｏｃｋｅｔ的阻塞和非阻塞两种工作模式。结合两个具体程序模型,讨论了在网络环境下发送/接收数据使用阻塞式socket的必要性和不足之处,并提出用能延时退出的阻塞式socket读写函数的解决方案。-Abstract : the Win32 platform (describes) socket obstruction and two non-blocking mode. Combining two specific program model discussed in the network environment to send / receive data using block-socket and the need for deficiencies, and make use can delay the withdrawal of obstructive type socket read and write function solutions.
