</B></FONT><FONT SIZE=3><P ALIGN="JUSTIFY">    </FONT><FONT FACE="宋体" LANG="ZH-CN" SIZE=3>在本节中，我们通过一个经过精心选择的例子，进一步讨论一下</FONT><FONT SIZE=3>Windows Sockets</FONT><FONT FACE="宋体" LANG="ZH-CN" SIZE=3>编程技术。例如如何编制客户机或服务器程序，如何应用</FONT><FONT SIZE=3>TCP</FONT><FONT FACE="宋体" LANG="ZH-CN" SIZE=3>有连接服务（流式套接口）或</FONT><FONT SIZE=3>UDP</FONT><FONT FACE="宋体" LANG="ZH-CN" SIZE=3>无连接服务（数据报套接口），如何进行阻塞或非阻塞方式的套接口操作等等，这些都是经常碰到的问题。接下来要介绍的</FONT><FONT SIZE=3>wshout</FONT><FONT FACE="宋体" LANG="ZH-CN" SIZE=3>程序，可以通过灵活地设置不同选项来达到上述应用情况的任意组合，从而基本覆盖了应用</FONT><FONT SIZE=3>Windows Sockets</FONT><FONT FACE="宋体" LANG="ZH-CN" SIZE=3>编程所可能碰到的问题，具有很好的研究参考价值。</P>
</FONT><FONT SIZE=3><P ALIGN="JUSTIFY">    </FONT><FONT FACE="宋体" LANG="ZH-CN" SIZE=3>由于该程序思路清晰，结构精良，所以我们不打算很详细地剖析每一个语句，而只是简要介绍一下整个程序的逻辑结构，并在源程序中加入适当的注释。我们相信，任何具有基本</FONT><FONT SIZE=3>C</FONT><FONT FACE="宋体" LANG="ZH-CN" SIZE=3>语言和</FONT><FONT SIZE=3>Windows</FONT><FONT FACE="宋体" LANG="ZH-CN" SIZE=3>编程经验的读者，都能很轻松地读懂绝大部分内容。经过仔细咀嚼和推敲后，更能得到一些编写优质程序的灵感。</P>
</FONT><FONT SIZE=3><P ALIGN="JUSTIFY">    </FONT><FONT FACE="宋体" LANG="ZH-CN" SIZE=3>该程序在</FONT><FONT SIZE=3>FTP</FONT><FONT FACE="宋体" LANG="ZH-CN" SIZE=3>公司的</FONT><FONT SIZE=3>PCTCP</FONT><FONT FACE="宋体" LANG="ZH-CN" SIZE=3>支撑环境下调试通过，不过只要读者拥有任何符合</FONT><FONT SIZE=3>Windows Sockets 1.1</FONT><FONT FACE="宋体" LANG="ZH-CN" SIZE=3>规范的实现，也能顺利执行该程序。</P>
