通过研究Linux的线程机制和信号量实现读者写者(Reader
通过研究Linux的线程机制和信号量实现读者写者(Reader-Writer)问题并发控制。
1)写-写互斥:不能有两个写者同时进行写操作;
2)读-写互斥:不能同时有一个线程在读,而另一个线程在写;
3)读-读允许:可以有一个或多个读者在读;
4)读者优先的附加限制:如果读者申请进行读操作时已有另一个读者正在进行读操作,则该读者可直接开始读操作;
5)写者优先的附加限制:如果一个读者申请进行读操作时已有另一个写者在等待访问共享资源,则该读者必须等到没有写者处于等待状态后才能开始读操作。
-By studying the Linux thread mechanism and semaphores realize readers who write (Reader-Writer) the issue of concurrency control. 1) to write- write mutex: Can not write at the same time there are two write operations 2) read- write mutex: Can not have a thread at the same time in reading and writing another thread 3) Reading- Reading of permit: can have one or more readers read 4) the priority of additional restrictions readers: If the readers apply for a read operation, there was another reader being read, the reader can be directly started reading operation 5) to write additional priority Restrictions: If an application for a reader reading write operation has been in waiting for another visit to a shared resource, the read

这个程序是模拟采用二级目录结构的磁盘文件系统中的文件操作,它可以实现对文件的一些基本管理,如:读、写、删除文件等。通过这个程序可掌握文件子系统的原理,加深对二级目录结构的文件系统中用户管理、文件管理、目录管理的理解,并用程序实现对文件子系统的模拟。-the procedure is simulated using two disk directory structure of the file system file manipulation, it can be achieved on some basic document management, such as : read, write, delete files. Through this procedure can grasp the principle document subsystems to enhance the structure of the two file system user management, document management, directory management, understanding, and the procedures to achieve the right documents subsystem simulation.
