How can I integrate C extensions with Cython?

Integrating C extensions with Cython involves creating a Cython file that declares the C functions you want to use. You then compile this file into a shared library.

What are the steps to create a Cython file for this?

First, create a .pyx file where you declare the C functions using cdef. Then, create a setup.py file to compile it using setuptools.

Can you provide an example of a simple C function and how to call it from Cython?

Sure! Here's a simple C function:

int add(int a, int b) {
    return a + b;
}

In your Cython file, you would declare it like this:

cdef extern from "your_c_file.h":
    int add(int a, int b)

And you can call it in a Cython function.

What tools do I need to compile Cython with C extensions?

You'll need a C compiler, Python, Cython, and setuptools. Make sure to have them installed and configured properly.
