The function initializes a random number generator and returns the state. The pointer to the state can be then passed to the :ocv:cfunc:`RandInt`, :ocv:cfunc:`RandReal` and :ocv:cfunc:`RandArr` functions. In the current implementation a multiply-with-carry generator is used.

:param mask: (For the second function only) Operation mask that should be a single-channel 8-bit image, 2 pixels wider and 2 pixels taller. The function uses and updates the mask, so you take responsibility of initializing the ``mask`` content. Flood-filling cannot go across non-zero pixels in the mask. For example, an edge detector output can be used as a mask to stop filling at edges. It is possible to use the same mask in multiple calls to the function to make sure the filled area does not overlap.

Since the mask is larger than the filled image, a pixel :math:`(x, y)` in ``image`` corresponds to the pixel :math:`(x+1, y+1)` in the ``mask`` .
