试验目的：通过研究Linux的线程机制和信号量实现生产者消费者问题的并发控制 说明：有界缓冲区内设有20个存储单元，放入/取出的数据项设定为1~20这20个整型数。 要求： (1)每个生产者和消费者对有界缓冲区进行操作后，即时显示有界缓冲区的全部内容.当前指针位置和生产者/消费者线程的标识符 (2)生产者和消费者各有两个以上 (3)多个生产者或多个消费者之间须共享对缓冲区进行操作的函数代码。-Test Objective : To study the Linux threading mechanism and signal to producers and consumers to achieve the concurrency control : a boundary buffer There are 20 storage units, Add/remove data items for a set of 20 ~ 20-integer. Requirements : (1) Each producer and consumer sector of the buffer zone is operated, immediately after the sector showed a buffer in its entirety. The current position and producer/consumer threads identifier (2) producers and consumers have two or more (3) A number of producers or many consumers to be shared between the right to operate the buffer function code.

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
