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

企业内部通讯系统必须提供网络通讯功能、在通讯过程中禁止使用聊天表情、文件传送等功能，避免资料外泄，或因发送错误而导致上级资料的丢失以及其他损失。最重要的是必须适应任何操作系统，也就是实现跨平台技术，因为企业内部的工作需要，工作环境中使用了多个操作系统来完成不同的工作。另外，系统不需要使用服务器中转和记录通讯内容，可以独立完成通讯任务，排除职工对领导监视工作进度等逆反心理-Internal communication systems to provide network communication capabilities, in the communications process of the Prohibition of the Use chat expressions, such as file transfer capabilities, to avoid leakage of information, or send an error which led to the loss of higher-level information as well as other losses. The most important thing is to be adapted to any operating system, which is cross-platform technology, as businesses need to work within the working environment in the use of a number of different operating system to complete the work. In addition, the system does not require the use of transit and records of communications servers, you can independently accomplish the communication task, remove the leadership of trade unions to monitor the progress of the work of such an antagonistic mental
