check_NID()

int check_NID	(	char *	bch_code,
		int *	new_nac,
		char *	new_duid,
		unsigned char	parity )

Checks a NID value, returns the fixed NAC, DUID and also an indication if it failed to decode the NID.

Parameters

bch_code	Input. An array to the 63 bytes, each containing one bit of the NID. This includes the NAC (12 bits), DUID (4 bits) and 47 bits of BCH parity.
new_nac	Output. An address where to store the calculated NAC value after error correction. Should be large enough to accommodate for an integer.
new_duid	Output. An address where to store the calculated DUID value after error correction. Should be able to accommodate 3 chars.
