实现UP、DOWN原语 产生3个进程： 两个进程模拟需要进入临界区的用户进程。 当需要进入临界区时，显示：“进程x请求进入临界区…”，同时向管理进程提出申请； 申请返回，表示进入了临界区。在临界区中等待一段随机时间，并显示：“进程x正在临界区…”； 当时间结束，显示：“进程x退出临界区…”,同时向管理进程提出退出申请； 当申请返回，显示：“进程x已退出临界区。” 一个进程作为原语的管理进程，接受其他进程的临界区进入请求： 如果允许进入，则根据DOWN 原语的操作步骤设置相应变量，然后返回； 如果不允许进入，则进入循环等待，直到允许为止； 退出时模拟UP 操作。 进程间通信可以采用信号、消息传递、管道或网络通信方式。 -achieve UP, DOWN original language have three processes : process simulation of two critical needs for access to the users in the process. When the need to access critical areas, revealed : "The process of x request to enter the critical areas ...", and also to the management process applications; applied to return, entered a critical area. In the critical area to wait for a certain period of time random, and that : "the process of x is the critical area ..."; When the time ended, showed : "x withdraw from the process of critical areas ...", and also to withdraw from the process management applications; When applied to ret

多数代码可以直接在Delphi6和Delphi7环境下运行。部分涉及.NET技术内容的代码，需要在Delphi 7上安装Borland .NET Complier for Delphi编译器方可编译执行。Borland已经正式推出Delphi 8 for .NET，所以本书范例中部分内容可能与D8最终版本不符。-most directly in the code and Delphi6 Delphi7 operating environment. Some involved.NET technology content of the code, the need to install Delphi 7 Borland.NET Complier for Delphi compiler can compile implementation. Borland has officially launched for Delphi 8.NET, the book example might be part of the final version D8 inconsistent.
