了解一个函数是否在C ++项目中调用？ [英] Find out if a function is called within a C++ project?

问题描述

我试图从C ++项目中删除未使用的函数。

I'm trying to remove functions that are not used from a C++ project. Over time it's become bloated and I'm looking to remove functions that aren't used at all.

我有一个解决方案文件在Visual Studio中的所有项目，但是，我使用cmake，所以我可以生成项目文件的另一个IDE，如果必要的（这就是为什么这没有用visual-studio标记）。

I have all the projects in a solution file in Visual Studio, but I use cmake so I can generate project files for another IDE if necessary (which is why this isn't tagged with visual-studio).

这样的东西是否存在？在哪里它将分析源并告诉我哪些函数不被调用。我在这里看到PC-Lint在一些问题中提到，但是似乎没有这样做。

Does something like this exist? Where it'll analyze the source and tell me which functions are not called. I saw PC-Lint mentioned in a few questions here, but that doesn't seem to do this.

我真正想做的是调用查找所有引用

What I really want to do is call "Find all references" on each function and remove the functions not called, but doing this manually would take much too long.

推荐答案

使用 __ declspec（deprecated）前面的函数声明你想摆脱。如果该函数在编译时实际使用，那么将抛出编译警告。

Use __declspec(deprecated) in front of the function declaration you want to get rid of. That will throw up compile warnings if that function is actually used at compile time.
