# Absolute Minimal Example
This is on Linux. As I write this I'm not sure how things are different with Windows, Cygwin and macos.

The C (in `mylib.c`):
```c
#include <stdio.h>

void print_number(int n) {
  printf("%d\n",n);
}
```


Compile with
```bash
gcc -shared -o mylib.so mylib.c
```

The Python
```py
import ctypes
lib = ctypes.cdll.LoadLibrary("./mylib.so")
lib.print_number(42)
```
