[Python-Dev] What do PyAPI_FUNC & PyAPI_DATA mean? (original) (raw)

Many (most?) of the function declarations in the CPython header files are annotated with the PyAPIFUNC declaration. Similarly for data declarations and PyAPIDATA

What do they mean, exactly? From the name I would expect that they are a way of declaring a function or datum to be part of the API, but their usage seems to be more to do with linkage.

They define linkage on Windows. I actually don't know if they should be applied to internal functions.
