2010操作系统实验及其参考答案(完整版)(8)

在开始本实验之前，请回顾教科书的相关内容。

您需要做以下准备：

1）一台运行Windows 2000 Professional 操作系统的计算机。 2）计算机中需安装Visual C++ 6.0 专业版或企业版。

7.4 实验内容与步骤

1. 虚拟内存的检测

使用VirtualQueryEX()函数来检查虚拟内存空间。

步骤1：登录进入Windows 2000 Professional。 步骤2：在“开始”菜单中单击“程序”、“Microsoft Visual Studio 6.0”“Microsoft Visual C++ 6.0”，进入Visual C++窗口。 步骤3：在工具栏单击“新建”按钮，编写代码保存为7-1.cpp。 功能：检测进程的虚拟地址空间

参考头文件与函数：windows.h、iostream、shlwapi.h、iomanip、 WalkVM（）、ZeroMemory()、GetSystemInfo(&si)、StrFormatByteSize()、 VirtualQueryEx()API

步骤4：单击“Build”菜单中的“Compile 7-1.cpp”命令，单击“是”按钮确认，系统对7-1.cpp进行编译。

步骤5：编译完成后，单击“Build”菜单中的“Build 7-1.exe”命令，建立7-1.exe可执行文件。

操作能否正常进行，如果不行，原因是什么？

步骤6：在工具栏单击“Execute program”按钮，执行7-1.exe程序。

运行结果（如果运行不成功，原因是什么？）：

按committed、reserved、free等三种虚拟地址空间分别记录实验数据，其中“描述”是指对该组数据的简单描述，例如：对下列一组数据：

00010000-00012000<8.00KB>Committed,READWRITE,Private可描述为：具有READWRITE权限的已调配私有内存区。

将系统当前的自由区（free）虚拟地址空间填入表7-3中。
