"Function definition for '' not found" message appears when defining a function with a macro

[dortamiguel]

Environment

• OS and Version: Ventura 13.6
• VS Code Version: 1.82.2
• C/C++ Extension Version: v1.17.5

Bug Summary and Steps to Reproduce

Bug Summary:

If I define a function with a macro vscode can't find the definition and it reports an error

Steps to reproduce:
Type this code

#define define_foo(Type) \
    void foo(const string &key, Type value) {}

define_foo(bool);
define_foo(char);

Expected behavior:
I don't get this error message

Other Extensions

No response

That error appears to be from another extension. Errors from our extension look like C/C++(<error code>). Your message shows no error code and doesn't match any error message we return.

@sean-mcmanus I only have the c++ extension installed

and if I disable it the message goes away, also this won't appear as an error. just three dots at the beginning of the string like in the screenshot

I reproduce the issue. This is a bug.

Ah, okay, I see now -- it's not an IntelliSense error (red squiggle) it's a CDD error message (from the "...").

The issue is inherited from the shared code from Visual Studio:

[J0shhT]

I've encountered this issue with class member functions. If you wrap the class part in a macro, it will think almost every function definition in the class doesn't exist, even if it does.

Example

Foo.hpp

#pragma once

#define CLASS(T) class T

CLASS(Foo)
{
public:
	void Bar();
	void Baz();
	void Test();
};

Foo.cpp

#include "Foo.hpp"

void Foo::Bar()
{
}

void Foo::Baz()
{
}

void Foo::Test()
{
}

Result

Oddly, it appears the first function in the class (Bar) doesn't have the issue, but the ones after it do (Baz and Test).

I'm observing the same, also very visible in Zephyr and it's macros for callback functions:
