在 c++ 中导出内联结构

Question

I was programming in c++ and I came across an issue. I had a struct for the player in a header file and wanted to use the struct in two different files.

 struct {
    float x;
    float y;

} player;

I tried many things and I did much research but it always resulted in errors or the variables not updating throughout all the files. However I made a discovery, you can use

inline struct EXPORT {
    float x;
    float y;

} player;

(c++17) Ive looked online and I cant find anyone talking about this, ive even searched "inline struct EXPORT" on github and no code results came up. I wonder if ive made a discovery. I am wondering if this is a known syntax and if it is a good idea to use such a function.

Answer 1

am wondering if this is a known syntax

Yes. The syntax of variable and class definition is known. In this case, you define an inline variable named player which is of a class type named EXPORT .

There is no "exporting" involved here.
