Read a hardware generated 16-bit random value and store the result in val. Returns 1 if a random value was generated, and 0 otherwise.

_rdrand32_step^⚠rdrand

Read a hardware generated 32-bit random value and store the result in val. Returns 1 if a random value was generated, and 0 otherwise.

_rdseed16_step^⚠rdseed

Read a 16-bit NIST SP800-90B and SP800-90C compliant random value and store in val. Return 1 if a random value was generated, and 0 otherwise.
