操作系统中进程同步的问题，生产者-消费者模型的代码



在同一个进程地址空间内执行的两个线程。生产者线程生产物品，

然后将物品放置在一个空缓冲区中供消费者线程消费。消费者线

程从缓冲区中获得物品，然后释放缓冲区。当生产者线程生产物

品时，如果没有空缓冲区可用，那么生产者线程必须等待消费者

线程释放出一个空缓冲区。当消费者线程消费物品时，如果没有

满的缓冲区，那么消费者线程将被阻塞，直到新的物品被生产出

来。

-Operating systems process synchronization problem, producers-consumer model code



In the same process within the address space of the two threads. Producers thread production items,

Then things placed on a empty buffer for consumers to thread consumption. Consumer line

Cheng gain items from buffer, and then release buffer. When producers thread production content

Product, if not empty buffer can be used, then producers have to wait for the consumer thread

Thread release a empty buffer. When consumer spending items thread, if not

Full buffer, so consumer thread will be blocked, until a new item to be produced
