Function Documentation

vsf_rng_init()

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
[in]	cfg_ptr	a pointer to structure vsf_rng_cfg_t

Returns

vsf_err_t: VSF_ERR_NONE if rng was initialized, or a negative error code

Note

It is not necessary to call vsf_rng_fini() to deinitialization. vsf_rng_init() should be called before any other rng API except vsf_rng_capability().

vsf_rng_fini()

void vsf_rng_fini

(

vsf_rng_t *

rng_ptr

)

finalize a rng instance.

Parameters

[in]

rng_ptr

a pointer to structure vsf_rng_t

Returns

none

vsf_rng_generate_request()

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	call back param
[in]	on_ready_cb	call back

Returns

vsf_err_t: VSF_ERR_NONE if rng generate request was successfully, or a negative error code

vsf_rng_capability()

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: return all capability of current rng vsf_rng_capability_t
