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
