* Name: getrandom
*
* Description:
* Fill a buffer of arbitrary length with randomness. This is the
* preferred interface for getting random numbers. The traditional
* /dev/random approach is susceptible for things like the attacker
* exhausting file descriptors on purpose.
*
* Note that this function cannot fail, other than by asserting.
* Fill a buffer of arbitrary length with randomness. This uses
* either /dev/random (if GRND_RANDOM flag) or /dev/urandom device and
* is therefore susceptible for things like the attacker exhausting file
* descriptors on purpose.
*
* Input Parameters:
* bytes - Buffer for returned random bytes
