_rdrand16_step(), _rdrand32_step(), _rdrand64_step()
Generate random numbers of 16/32/64 bit wide random integers. These intrinsics are mapped to the hardware instruction RDRAND.
Syntax
extern int _rdrand16_step(unsigned short *random_val); |
extern int _rdrand32_step(unsigned int *random_val); |
extern int _rdrand64_step(unsigned __int64 *random_val); |
Description
These intrinsics generate random numbers of 16/32/64 bit wide random integers. The generated random value is written to the given memory location and the success status is returned: '1' if the hardware returned a valid random value, and '0' otherwise.
Returns
1 : if the hardware returns a 16/32/64 random value.
0 : if the hardware does not return any random value.
