Description: 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。

Description: The main purpose of this paper is to demonstrate how to create a PDF writer by using Virtual Printer Method, which gives your applications an ability to generate PDF file through simply "printing". I am pretty sure there are many PDF writers using the same technique, saying PrimoPDF (http://www.primopdf.com/ ). However you probably wish to create your own PDF writer in some day. I here give an example to uncover the whole process of creating such kind of PDF writer.

Description: 在Windows2000或Windows XP环境下，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。-In Windows2000 or Windows XP environment, the creation of a console process, this process contains n threads. Using this n that n threads to a reader or writer. Each thread in accordance with the corresponding test data files to read and write operation requirements. Semaphore mechanism with the respective priorities and the achievement of the readers who write priority issue.

Description: This program uses the HF flag of a FIFO to trigger reads, guaranteeing that the FIFO is never blocked for the writer, giving high throughput for the reader (bursts of D/2 = 128) and guaranteeing that the the reader will not be stuck in the top half of the FIFO.

-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 reader must wait until those who had not been written in a wait state after the read operation can begin.
