描述

bug Feature: Doc comments Language Service Visual Studio
Environment
  • OS and Version: Windows 11
  • VS Code Version: 1.136.1
  • C/C++ Extension Version: 1.5.1
Bug Summary and Steps to Reproduce

Bug Summary:

When hovering over function definition, the comments of the macro creating the function name is shown instead of the function's ones.

Steps to reproduce:

Write this code:

// hello
#define deffunc(name) name
int deffunc(funcA)();

int main(){
    funcA();
    return 0;
}

and hover over funcA. hello is displayed instead of nothing.

I saw this behaviour first in AudioKinetic's SDK, due to there being a ton of macro for function export so I suspect this is a bug.
