windows进程管理实验报告

1、成绩：实 验 报 告课程名称：操作系统实验项目：windows进程管理姓 名：专 业：计算机科学与技术班 级：学 号：计算机科学与技术学院计算机系2019 年 4 月 23 日实验项目名称： windows进程管理 一、实验目的1. 学习windows系统提供的线程创建、线程撤销、线程同步等系统调用；2. 利用C+实现线程创建、线程撤销、线程同步程序；3. 完成思考、设计与练习。二、实验用设备仪器及材料1. Windows 7或10， VS2010及以上版本。三、实验内容1 线程创建与撤销写一个windows控制台程序（需要MFC），创建子线程，显示Hello, This is a Threa

2、d. 然后撤销该线程。相关系统调用：线程创建： CreateThread()线程撤销： ExitThread()线程终止： ExitThread(0)线程挂起： Sleep()关闭句柄： CloseHandle()参考代码：/ OS-TEST.cpp : 定义控制台应用程序的入口点。/#include stdafx.h#include OS-TEST.h#ifdef _DEBUG#define new DEBUG_NEW#endif/ 唯一的应用程序对象CWinApp theApp;using namespace std;void ThreadName1();int _tmain(int ar

5、)printf(Hello, This is a Thread.);运行结果如图所示。完成以下设计题目：1. 向线程对应的函数传递参数，如字符串“hello world！”，在线程中显示。2. 如何创建3个线程A, B, C，并建立先后序执行关系ABC。实验内容2 线程同步完成父线程和子线程的同步。父线程创建子线程后进入阻塞状态，子线程运行完毕后再唤醒。相关系统调用：等待对象 WaitForSingleObject(), WaitForMultipleObjects();信号量对象 CreateSemaphore(), OpenSemaphore(), ReleaseSemaphore();

6、HANDLE WINAPI CreateSemaphore( _In_opt_ LPSECURITY_ATTRIBUTES lpSemaphoreAttributes _In_ LONG lInitialCount, _In_ LONG lMaximumCount, _In_opt_ LPCTSTR lpName );第一个参数：安全属性，如果为NULL则是默认安全属性第二个参数：信号量的初始值，要=0且=第三个参数第三个参数：信号量的最大值第四个参数：信号量的名称返回值：指向信号量的句柄，如果创建的信号量和已有的信号量重名，那么返回已经存在的信号量句柄参考代码：/ OS-TEST.cpp :

12、r=%dn,err);if(rc=0) printf(Semaphore Release Fail.n);else printf(Semaphore Release Success. rc=%dn,rc);编译运行，结果如图所示。完成以下设计题目：3. 用信号量控制实现3个线程的同步，线程A释放信号量后执行B，B释放信号量后执行C。 四、实验结果实验内容11. 向线程对应的函数传递参数，如字符串“hello world！”，在线程中显示。结果：/ 66645.cpp : 定义?控?制?台应|用?程序的?入?口点?。/#include stdafx.h#include 66645.h#ifdef
