The Python C API

The C API is divided into these sections:

Include/: Limited API
Include/cpython/: CPython implementation details
Include/cpython/, names with the PyUnstable_ prefix: API that can change between minor releases
Include/internal/, and any name with _ prefix: The internal API

Information on changing the C API is available in the developer guide
