题目二:用多进程同步方法解决生产者-消费者问题。



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.



设计要求:(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有共享对缓冲区进行操作的函数代码.-Title 2: The multi-process synchronization solution to the producer- consumer issues. Descr iption: bounded buffer is equipped with 20 memory units, into/out of the data item is set to 1-20 these 20 integers. Design requirements: (1) Each producer and consumer to have the community buffer zone to operate immediately after showing the entire contents of the buffer sector, the current pointer position and the producer/consumer thread identifier. (2) producers and consumers have more than two. (3) A number of production or more consumers shall be shared between the operation of the buffer function of the code.
