How can I access the buffer of CryptGenRandom?

This question is inspired by this answer on Crypto SE.

According to Niels Ferguson's Whitepaper called 'The Windows 10 random number generation infrastructure', the CryptGenRandom algorithm uses a buffer for small requests:

All PRNGs in the system are SP800-90 AES_CTR_DRBG with 256-bit security strength using the df() function for seeding and re-seeding (see SP 800-90 for details). (…) The Basic PRNGs are not used directly, but rather through a wrapping layer that adds several features.

• A small buffer of random bytes to improve performance for small requests.
• A lock to support multi-threading.
• A seed version.

(…) The buffering is straightforward. There is a small buffer (currently 128 bytes). If a request for random bytes is 128 bytes or larger, it is generated directly from AES_CTR_DRGB. If it is smaller than 128 bytes it is taken from the buffer. The buffer is re-filled from the AES_CTR_DRBG whenever it runs empty. So, if the buffer contains 4 bytes and the request is for 8 bytes, the 4 bytes are taken from the buffer, the buffer is refilled with 128 bytes, and the first 4 bytes of the refilled buffer are used to complete the request, leaving 124 bytes in the buffer.

I would like to know if it is possible to access this buffer from my Windows 10 laptop, and if so how I can implement this.

I looked at the Windows page of CryptGenRandom, and this page does also mention a buffer which is given as input. However, this is a different buffer from the one in the whitepaper: in this buffer, the output bytes will be written. Therefore, the buffer has a different size and purpose than the buffer that I am interested in.
