Function definition can't be found when the implementation is done in a macro

[dortamiguel]

Environment

• OS and Version: macOS Sonoma 14.5
• VS Code Version: 1.96.2
• C/C++ Extension Version: 1.22.11

Bug Summary and Steps to Reproduce

I have the following code that defines the implementation of a function using a macro

struct Foo {
    void hello();
};

#define FOO_HELLO() \
    void Foo::hello() {}

FOO_HELLO();

But I'm getting the following warnings:

Since hello is actually defined I would expect not seeing this warning

@dortamiguel I've reported a bug on our shared implementation with VS at https://developercommunity.visualstudio.com/t/C-Create-Definition-suggestions-dont/10826411

@dortamiguel It turns out this is "by design" and you need to add the macros to a cpp.hint file, such as

#define FOO_HELLO() void Foo::hello() {}

and then do a Reload Window.

@sean-mcmanus could be possible to just turn off the warning then?

I'm using macros to generate declarations so I don't have to type them, if I have to type the definition in a hint file then there is no point of using the macro at all
