  7. <h3>Name</h3>
  8. random - kernel randomness source
  9. <h3>Synopsis</h3>
  10. device random0 at lrandom*<br>

  12. <h3>Description</h3>
  13. The random device is the generalized interface to randomness sources.
  14. Only one random device is used; if more are attached they are ignored.
  15. If no random device is found, the kernel may not run.
  16. <p>
  17. The random device provides both the in-kernel random() function and a
  18. VFS character device, called <tt>random:</tt>. Bytes read from the
  19. latter have random values; writes are discarded.
