Functions
void	sys_rand_get (void *dst, size_t len)
	Fill the destination buffer with random data values that should pass general randomness tests.
int	sys_csrand_get (void *dst, size_t len)
	Fill the destination buffer with cryptographically secure random data values.
static uint8_t	sys_rand8_get (void)
	Return a 8-bit random value that should pass general randomness tests.
static uint16_t	sys_rand16_get (void)
	Return a 16-bit random value that should pass general randomness tests.
static uint32_t	sys_rand32_get (void)
	Return a 32-bit random value that should pass general randomness tests.
static uint64_t	sys_rand64_get (void)
	Return a 64-bit random value that should pass general randomness tests.

Detailed Description

Random number generator header file.

This header file declares prototypes for the kernel's random number generator APIs.

Typically, a platform enables the appropriate source for the random number generation based on the hardware platform's capabilities or (for testing purposes only) enables the TEST_RANDOM_GENERATOR configuration option.
