[Process-Thread] The-problem-of-product-and-consume DL : 0: 生产者-消费者问题是一个经典的进程同步问题，该问题最早由Dijkstra提出，用以演示他提出的信号量机制。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。-The producer- consumer question is a classical advancement synchronization question, this question proposed most early by Dijkstra, with demonstrates the signal quantity mechanism which he proposed.Two threads carries out which in the identical advancement address space.The producer thread production goods, then lay aside the goods in a spatial buffer supply the consumer thread expense.The consumer thread obtains the goods from the buffer, then release buffer.When producer thread production goods, if does not have the spatial buffer available, then the producer thread must wait for the consumer thread releases a spatial buffer.When consumer thread expense goods, if does not have the full buffer, then the consumer thread is blocked, is produced until the new goods.
