Review Comment:
This line is a statement that evaluates to a boolean and discards the
result; it does not perform any validation. To make this test effective, it
should be an `assert` statement. Based on the behavior of `ctypes.c_void_p(0)`,
its `.value` is `None`. The `fecho` function should return an equivalent
`c_void_p` object, so you should assert that the returned object's value is
`None`.
For completeness and consistency with the preceding test for `c_void_p`, you
might also consider adding `assert isinstance(c_void_p_nullptr_result,
ctypes.c_void_p)` before this line.
```suggestion
assert c_void_p_nullptr_result.value is None
```
