Export real functions for things that currently exist as macros / defines / global variables in the C code

ファイル、テスト、または特定の API エントリは挙げられていません。まず C DLL API を確認し、言及されているマクロ、define、グローバル変数を調べます。関数の代替案を限定した集合として定義し、選択した項目がエクスポートされ、より高レベルの wrapper から使用可能であることを検証します。

Pitch

I am writing a python wrapper in a higher level language using the C DLL API. Within certain higher level languages, it is not easily possible to access anything other than the exported functions from the DLL. Macros / defines / global variables are troublesome to interact with from the DLL.

So, If I only have easy access to the function API in my higher level language, type checking sort of becomes an issue due to things like PyList_Check being a macro and PyList_Type being a global variable. Exposing global variables (such as PyList_Type) through function APIs that just return a pointer to the data (for example) prevents a structure re layout from leaking out of the DLL... not to mention gives easier access to the data I need to call a type check function.

For things like PyList_Check that are macros, but are still useful for direct checks, they could be converted to a function API.

(Explain why this feature or enhancement should be implemented and how it would be used.
Add examples, if applicable.)

I do not suggest converting macros / defines cold turkey into a function API... obviously, that could break a lot of code for users of the C library. Instead, provide function alternatives to the items as a parallel API for those of us that can only really call DLL functions in our higher level language. As I go through some of the C API, I do notice areas where a macro and a function form of an API do exist in parallel. It would be nice if we could continue to extend that, especially for type checks.
