Retrieve current NumPy seed

The following imports NumPy and sets the seed.

import numpy as np
np.random.seed(42)

However, I'm not interested in setting the seed but more in reading it. random.get_state() does not seem to contain the seed. The documentation doesn't show an obvious answer.

How do I retrieve the current seed used by numpy.random, assuming I did not set it manually?

I want to use the current seed to carry over for the next iteration of a process.
