Typedef Documentation

typedef void(* rng_monitor_notification_handler_t)(void *p_context)

Function handling RNG Monitor notifications.

Parameters

[in]

p_context

Pointer user defined context

Function Documentation

ret_code_t rng_monitor_init

(

void

)

Initializes RNG Monitor.

Note

The nrf_drv_rng driver has to be initialized before calling this function.

		rng_monitor_notification_handler_t	notification_handler,
		void *	p_notification_context
	)

Request radnom data read.

Parameters

[in]	random_bytes_requested	Number of random bytes requested.
[in]	notification_handler	Function which will be called when there will be enough random bytes in RNG pool.
[in]	p_notification_context	Context passed to notification handler.

Returns

NRF_SUCCESS on success, otherwise an error code.
