任何找到使用malloc / realloc动态分配的内存大小的工具？ [英] Any tool to find size of memory allocated dynamically using malloc/realloc?

问题描述

我有一个具有所有c代码的MS-Visual Studio 2005工作空间。该应用程序（exe）使用malloc和realloc从heap中动态分配内存。当我运行特定的测试用例时，我想使用这个应用程序使用malloc / realloc在堆上计算最大分配的大小。

我不想更改代码通过注意到malloc大小并累积它们，因为：

a）可能会有一个场景，1KB的一些内存是malloc'ed，然后被释放，然后一个2KB的内存是malloc'ed。所以最大是2KB，我需要得到的值不是1 + 2 = 3KB。

所以我必须真正看到这里malloc / free发生了什么代码和添加代码，我想避免。

1）所以有什么工具（免费软件/许可）找到动态分配的最大或总内存的大小使用malloc / realloc？

2）MS Visual Studio 2005/2008本身是否提供了这样的任何东西？

谢谢，

解决方案

内存验证器可以做到

有几种不同的报告，您会发现有用的：

• 运行总计。这是一个对话框，提供每个主内存分配器（C运行时，HeapAlloc，LocalAlloc，GlobalAlloc，CoTaskMemAlloc等）的当前累积值和总值。




• 对象。这是主要选项卡之一，显示对象类型，大小，计数，累积。
  每个线程和每个dll值也是子选项。




• 大小。这是主要选项卡之一，并显示大小，计数，累积。
  每个线程和每个dll值也是subtab。




• 虚拟。这将显示内存的图形视图（一个像素==一页内存），并显示虚拟内存页面和虚拟内存段落的详细虚拟内存数据的子选项。

I have a MS-Visual Studio 2005 workspace having all c code. This application(exe) allocates memory dynamically from heap using malloc and realloc. I want to calculate the maximum size allocated size allocated on heap using malloc/realloc by this application program when i run particular test case.

I do not want to change the code by noting the malloc sizes and accumulating them, because:

a) there can be a scenario, that some memory of 1KB is malloc'ed, then freed, and then a memory of 2KB is malloc'ed. So max is 2KB, which i need to get as the value and not 1+2=3KB.

So i have to really see whereall malloc/free is happening in this code and add code for this, which i want to avoid.

1) So are there any tools(freeware/licensed) to find size of maximum or total memory allocated dynamically using malloc/realloc?

2)Does MS Visual Studio 2005/2008 itself provide anything of this sort?

thanks,

解决方案

Memory Validator can do this.

There are several different reports that you will find useful:

• Running Totals. This is presented as a dialog box and provides current, cumulative and total values for each of the main memory allocator (C runtime, HeapAlloc, LocalAlloc, GlobalAlloc, CoTaskMemAlloc, etc).

• Objects. This is one of the main tabs and displays object type, size, count, cumulative. Also subtabs for per-thread and per-dll values.

• Sizes. This is one of the main tabs and displays size, count, cumulative. Also subtabs for per-thread and per-dll values.

• Virtual. This displays a graphical view of memory (one pixel == one page of memory) and has subtabs showing detailed virtual memory data for virtual memory pages and virtual memory paragraphs.
