Function Documentation

_rdseed16_step()

static __inline__ int __DEFAULT_FN_ATTRS _rdseed16_step ( unsigned short *  __p )

static

Stores a hardware-generated 16-bit random value in the memory at __p.

The random number generator complies with NIST SP800-90B and SP800-90C.

IF HW_NRND_GEN.ready == 1
  Store16(__p, HW_NRND_GEN.data)
  result := 1
ELSE
  Store16(__p, 0)
  result := 0
END

This intrinsic corresponds to the RDSEED instruction.

Parameters

__p	Pointer to memory for storing the 16-bit random number.

Returns

1 if a random number was generated, 0 if not.

_rdseed32_step()

static __inline__ int __DEFAULT_FN_ATTRS _rdseed32_step ( unsigned int *  __p )

static

Stores a hardware-generated 32-bit random value in the memory at __p.

The random number generator complies with NIST SP800-90B and SP800-90C.

IF HW_NRND_GEN.ready == 1
  Store32(__p, HW_NRND_GEN.data)
  result := 1
ELSE
  Store32(__p, 0)
  result := 0
END

This intrinsic corresponds to the RDSEED instruction.

Parameters

__p	Pointer to memory for storing the 32-bit random number.

Returns

1 if a random number was generated, 0 if not.
