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
