读者-写者问题(Courtois et al., 1971)
读者-写者问题为数据库访问建立了一个模型。例如,一个系统,其中有许多竞争的进程试图读写其中的数据,多个进程同时读是可以接受的,但如果一个进程正在更新数据库,则所有的其他进程都不能访问数据库,即使读操作也不行。问题是:如何对读者和写者进行编程。

创建一个控制进程,此进程包含n个线程。用这n个线程来表示n个读者或写者。每个线程按相应测试数据文件的要求进行读写操作。用信号量机制分别实现读者优先和写者优先问题。运行结果显示要求:要求在每个线程创建、发出读写申请、开始读写操作和结束读写操作时分别显示一行提示信息,以确定所有处理都遵守相应的读写操作限制。

创建一个控制台进程,此进程包含n个线程,用这n个线程来表示n个读者或写者,每个线程按相应测试数据文件(后面有介绍)的要求进行读写操作,用信号量机制分别实现读者优先和写者优先的读者-写者问题。
读者-写者问题的读写操作限制(包括读者优先和写者优先):
写-写互斥,即不能有两个写者同时进行写操作。
读-写互斥,即不能同时有一个线程在读,而另一个线程在写。
读-读允许,即可以有一个或多个读者在读。
读者优先的附加限制:如果一个读者申请进行读操作时已有另一个读者正在进行读操作,则该
