Function Documentation

max_trng_fill_buffer()

int max_trng_fill_buffer	(	struct no_os_trng_desc *	desc,
		uint8_t *	buff,
		uint32_t	len )

Fill buffer with random numbers.

Parameters

desc	- The device structure.
buff	- Buffer to be filled.
len	- Length of the buffer.

Returns

0 in case of success, negative error code otherwise.

max_trng_init()

int max_trng_init	(	struct no_os_trng_desc **	desc,
		const struct no_os_trng_init_param *	param )

Initialize the device.

Parameters

desc	- The device structure.
param	- The structure that contains the device initial parameters.

Returns

0 in case of success, negative error code otherwise.

max_trng_remove()

int max_trng_remove

(

struct no_os_trng_desc *

desc

)

Remove the device and release resources.

Parameters

desc	- The device structure.

Returns

0 in case of success, negative error code otherwise.
