Description
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.
