如何知道某个宏在Visual Studio中定义的位置 [英] How to know where a certain macro is defined in Visual Studio

问题描述

我目前有一个使用DirectX的Visual Studio项目.代码中有一些宏，例如

I currently have a visual studio project that uses DirectX. There are some macros in the code such as

__range(0, m_lBatchSize)  LONG  m_nBatched;
__field_ecount_opt(m_lBatchSize) IMediaSample  **      m_ppSamples;

我想知道这些宏在哪些文件中定义.通常在Visual Studio中，我将单击goto定义，然后转到definitio.在这种情况下，它不会带我到任何地方.该功能对宏有效吗?有什么办法让我找出在何处定义此宏?

I wanted to know which files these macros are defined in. Normally in Visual Studio I would click goto definition and it would take me to the definitio. It is not taking me anywhere in this case. Does that feature work for macros ? Is there any way for me to find out where this macro is defined ?

推荐答案

我的诀窍是

#define __range FOO

在我的代码中，预处理器会说

in my code, the preprocessor will then say

__range already defined at xxxx.nn
