操作系统生产者消费者问题C语言VIP专享

《操作系统概念》第七版 中的实验项目：生产者消费者问题

本程序中，main()函数需要三个参数：主线程休眠时间；生产者线程数；消费者线程数

各线程的休眠等待时间是随机的

程序代码：#include〈stdio

h〉#include#include＃define BUFFER_SIZE 5typedef int buffer_item;struct v｛int i;}；buffer_item buffer[BUFFER_SIZE+1］;buffer_item front=0,rear=0;HANDLE mutex，empty,full；int insert_item（buffer_item item）｛/*insert item into bufferreturn 0 if successful，otherwise return -1 indicating an error condition*/if((rear+1）%（BUFFER_SIZE+1)==front)return 1;buffer[rear]=item;rear=（rear+1）%（BUFFER_SIZE+1）;return 0；}int remove_item(buffer_item *item)｛/＊remove an object from buffer placing it in item return 0 if successful,otherwise reutrn -1 indication an error condition */if(front == rear)return 1;＊item=buffer[front];front=(front+1） % (BUFFER_SIZE+1)；return 0；｝DWORD WINAPI producer(PVOID Param){int rand1；
