Function Documentation

_copy()

unsigned int _copy	(	uint8_t *	to,
		unsigned int	to_len,
		const uint8_t *	from,
		unsigned int	from_len
	)

Copy the the buffer 'from' to the buffer 'to'.

Returns

returns TC_CRYPTO_SUCCESS (1) returns TC_CRYPTO_FAIL (0) if: from_len > to_len.

Parameters

to	OUT – destination buffer
to_len	IN – length of destination buffer
from	IN – origin buffer
from_len	IN – length of origin buffer

_set()

void _set	(	void *	to,
		uint8_t	val,
		unsigned int	len
	)

Set the value 'val' into the buffer 'to', 'len' times.

Parameters

to	OUT – destination buffer
val	IN – value to be set in 'to'
len	IN – number of times the value will be copied
