prng_seedctlLoads and updates the kernel PRNG seed file

The prng_seedctl loads the kernel PRNG seed file at /var/db/SystemEntropyCache (if present) and writes it to /dev/random. It then calls getentropy(2) to get a new seed to update the seed file.

The prng_seedctl utility exits 0 on success and greater than 0 on error.
