有没有一种方法可以在Visual Studio中获取某些c ++函数的调用图? [英] Is there a way to get a call graph for certain c++ function in Visual Studio?

问题描述

我想知道是否有一个VS工具可以为我显示给定C ++函数的调用图(即列出所有可能执行路径的图).如果仅在几个地方调用函数，这将有助于导航大型代码库.

对于像printf这样的经常调用的函数，它可以简单地说:

太多选择...

同样，我想制作这样的工具并不容易，所以我想知道它是否存在，但是您知道这样做似乎有可能，所以您永远都不知道...

我知道找到所有引用，但这仅给出了函数的调用站点，而不是给出了调用函数的函数的调用站点……

VS是2010，但如有必要，可以选择VS2012.

解决方案

您提到您了解有关查找所有引用的知识.您是否看过Call Hierarchy?它可能不是您的梦想方法"，但确实允许您根据给定函数的调用"和来自"的调用来查看函数.该窗口还允许您添加多个功能以树状格式查看.因此，基本上，您会在可能的结果中大跌眼镜.

右键单击所需的方法(可以在层次结构中的任何位置)=>

选择查看呼叫层次结构"

请注意，如果可以在窗口中添加多个参考点.在需要时删除

您还可以使用Ctrl + K或Ctrl + T

另一个很好的例子，恕我直言，令人失望的是C ++和C#与VS之间的差异.我认为代码映射正是您所需要的.当然，假设您使用的是Ultimate，但不，不是使用C ++.

I wonder whether there is a tool for VS that can show me a call graph (that is, a diagram listing all possible execution paths) for a given C++ function. It would help in navigating a big code base, in cases where a function is called in only a few places.

For oft-called functions like printf it could simply say:

too many options...

Again I guess it is not really easy to make such tool so I wonder if it exists, but you know it seems possible to do it so you never know... :)

EDIT: I know about find all references, but that gives just call sites of the function, not the call site of the function that called the function that called the function...

EDIT: VS is 2010, but if necessary VS2012 is an option.

解决方案

You mentioned that you know about finding all the references. Have you looked into viewing the Call Hierarchy? It's probably not your "dream method" but it does allow you to look at a function in terms of "calls to" and "calls from" the given function. The window also allows you to add multiple functions to view in a tree format. So basically you would tree up or down through the possible outcomes.

Right click on the desired method ( could be anywhere in the hierarchy ) =>

Select "View Call Hierarchy"

Note that if you can add more than one reference point to the window. Delete when needed

You could also use Ctrl+K or Ctrl+T

Another fine example, IMHO, of a disappointment in the differences between C++ and C# with VS. I think Code Maps would be just what you're looking for. Assuming of course you were working with Ultimate - but nope, not with C++.
