Yes I know. Read up how importing works.

The return type of C functions wrapped by `ctypes` is always `int` until
you say otherwise. How to do that is covered in the `ctypes`
tutorial/dicumentation.

This binds the resulting "pointer" object to the name
`shared_memory_pointer`.

And here you bind a different object to that name, so the first binding
has no effect.
