操作系统实验课（一）进程的创建与销毁

根据老师给的实验指导书做的

# include 
# include 
# include 

int main()
{
	STARTUPINFO si;
	PROCESS_INFORMATION pi;
	ZeroMemory(&si, sizeof(si));
	si.cb = sizeof(si);
	ZeroMemory(&pi, sizeof(pi));
	TCHAR szCommandLine[] = TEXT("first");
	if (!CreateProcess(NULL,
					   szCommandLine,
					   NULL,
					   NULL,
					   FALSE,
					   0,
					   NULL,
					   NULL,
					   &si,
					   &pi))
	{
		fprintf(stderr, "Createprocess Failed \n\n\n");
		system("pause");
		exit(0);
	}

	int x;
	while (true)
	{
		printf("请输入要选择的操作：\n0:销毁进程\n1:挂起进程\n2:激活进程\n3:退出\n");
		scanf("%d",&x);
		switch (x)
		{
			case 0:
				if (TerminateProcess(pi.hProcess, 0))
					printf("进程销毁成功");
				break;
			case 1:
				if (SuspendThread(pi.hThread))
					printf("挂起进程成功");
				else
					printf("挂起失败");
				break;
			case 2:
				if (ResumeThread(pi.hThread))
					printf("激活进程成功");
				else
					printf("激活失败");
				break;
			case 3:
				exit(0);
			default:
				printf("选项不正确");
		}
	}
    return 0;
}

如果把szCommandLine字符串的内容改成跟代码文件的名字相同，会发生有意思的事情哦，比如文件名first.cpp哈代码中TCHAR szCommandLine[] = TEXT("first");这句，很有意思的哦，嘿嘿嘿……
