windows进程管理实验报告

1、成绩:实验报告操作系统windows进程管理计算机科学与技术课程名称:实验项目姓名:专业: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、实验目的学习windows系统提供的线程创建、线程撤销、线程同步等系统调用;利用C+实现线程创建、线程撤销、线程同步程序；完成思考、设计与练习。二、实验用设备仪器及材料Windows7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,ThisisaThread.然后撤销该线程。相关系统调用：线程创建：CreateThread(

2、)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。/#includestdafx.h#includeOS-TEST.h#ifdef_DEBUG#definenewDEBUG_NEW#endif/唯一的应用程序对象CWinApptheApp;usingnamespacestd;voidThreadName1();int_tmain(intargc,TCHAR*argv,TCHAR*envp)intnRetCode=0;staticHANDLEhHand

5、：向线程对应的函数传递参数，如字符串“helloworld!”，在线程中显示。如何创建3个线程A,B,C,并建立先后序执行关系A-BC。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();HANDLEWINAPICreateSemaphore(_In_opt_LPSECURITY_ATTRIBUTESlpSemapho

6、reAttributes_In_LONGllnitialCount,_In_LONGlMaximumCount,_In_opt_LPCTSTRlpName)；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:定义控制台应用程序的入口点。/#includestdafx.h#includeOS-TEST.h#ifdef_DEBUG#definenewDEBUG_NEW#end
