GMPy - type checking in python C-api

Question

I am trying to understand how to type check using python C-api.

To achieve this, I am studing the source code of GMPy, where they check if the argument to a function is an integer using the macro IS_INTEGER(x), which itself is defined based on a function PyInt_Check.

However, I tried grep "PyInt_Check" -r and I cannot find the definition of PyInt_Check in the source code.

What am I doing wrong? Shouldn't the definition of PyInt_Check be on the GMPy folder?

Might it be in a header that GMPy uses instead? – DavidW May 08 '19 at 17:17 — DavidW, May 08 '19 at 17:17

PyInt_Check is part of the python c-api, and you'll find it declared in your copy of python.h. You can read the details online https://docs.python.org/2.7/c-api/int.html#c.PyInt_Check
