How can I use C libraries in Cython?

You can use C libraries in Cython by declaring the C functions and types in a .pyx file and then compiling it.

Can you give me a simple example?

Sure! First, create a C header file, say mylib.h, with your C functions. Then, in your .pyx file, you can declare them like this:

cdef extern from "mylib.h":
    int my_function(int x)

After that, you can call my_function in your Python code.

What do I need to compile the Cython code?

You'll need a C compiler and a setup.py file to build your Cython module. You can use setuptools for that.

Is there any specific setup I need for Windows?

On Windows, you might need to install Visual Studio Build Tools to get a compatible C compiler. Make sure to configure your environment variables accordingly.
