There are few ways to go:
1. Create thin wrapper around X, which holds x, and use it for
arguments and return type
2. Expose "x" address and use ctypes module
3. Create "more" Pythonic interface for the functionality.

Boost.Python doesn't allow you to pass by pointer\non-const reference
"Python" immutable types.
