I was coding c++ with clang and I had to use the offsetof macro for something but the C/C++ IntelliSense tell me that there’s a identifier "offsetof" is undefined error, even though it compiles and works just fine. I went to its Defination and it took me to __stddef_offsetof.h header file where I see another error squiggles for the __building_module, the error is expression preceding parentheses of apparent call must have (pointer-to-) function type. now I don’t know what any of that means so i asked chat gpt and it says I should consider Updating your IDE and its C++ support packages. but I it already up to date nd stills shows errors. I am on ubuntu please let me know if u know something about this. please do let me know if you wanna know something.

#if !defined(offsetof) ||                                                      
    (__has_feature(modules) && !__building_module(_Builtin_stddef))
#define offsetof(t, d) __builtin_offsetof(t, d)
#endif
