当内存位置的内容更改或读取时自动中断 [英] Automatic break when contents of a memory location changes or is read

问题描述

旧的DEC Tru64 UNIX调试器具有一个功能（称为监视变量的观察点），该功能将监视读取或写入活动的内存位置（或地址范围），并在检测到此类活动时破坏程序，可以调查为什么。详情请参阅：

The old DEC Tru64 UNIX debugger had a feature (called "watchpoints to monitor variables") that would watch a memory location (or range of addresses) for read or write activity and when it detected such activity would break the program so you could investigate why. See for details:

有任何方法做这样的事情在VisualStudio调试器？

Is there any way to do this sort of thing in the VisualStudio debugger? Or is there an add-on or some other tool that can do this under Windows?

推荐答案

是的，你可以这样做视觉工作室。在正在运行的程序中断开时，可以在调试菜单下创建新数据断点。然后指定要观看的地址和字节数。

Yeah, you can do this in visual studio. You can create a "New Data Breakpoint" under the debug menu while you're broken in a running program. You then specify the address to watch and the number of bytes.

这只适用于更改值。我不知道如何观看读取访问。然而，这是一个很常见的问题，想知道一个值发生了什么变化。我发现我不想知道谁经常读取值。

This only works for changing the value. I don't know how to watch for read access. However it's a very common question to want to know where a value got changed. I find that I don't want to know who reads a value as often.
