◆ VSF_RNG_CFG_FUNCTION_RENAME

#define VSF_RNG_CFG_FUNCTION_RENAME DISABLED

vsf_err_t vsf_rng_init ( vsf_rng_t * rng_ptr )

Initialize a RNG instance.

Parameters

[in] rng_ptr a pointer to structure vsf_rng_t

Returns: vsf_err_t: VSF_ERR_NONE if initialization successful, otherwise returns error code

Note: It is not necessary to call vsf_rng_fini() to deinitialize. vsf_rng_init() should be called before any other RNG API except vsf_rng_capability().

void vsf_rng_fini ( vsf_rng_t * rng_ptr )

Finalize a RNG instance.

Parameters

[in] rng_ptr a pointer to structure vsf_rng_t

vsf_err_t vsf_rng_generate_request	(	vsf_rng_t *	rng_ptr,
		uint32_t *	buffer,
		uint32_t	num,
		void *	param,
		vsf_rng_on_ready_callback_t *	on_ready_cb
	)

RNG generate request.

Parameters

[in]	rng_ptr	a pointer to structure vsf_rng_t
[in]	buffer	RNG data buffer
[in]	num	the length of RNG data buffer
[in]	param	callback parameter
[in]	on_ready_cb	callback function

Returns: vsf_err_t: VSF_ERR_NONE if the request was successful, otherwise returns error code

vsf_rng_capability_t vsf_rng_capability ( vsf_rng_t * rng_ptr )

Get the capability of RNG instance.

Parameters

[in] rng_ptr a pointer to structure vsf_rng_t

Returns: vsf_rng_capability_t: All capabilities of current RNG vsf_rng_capability_t
