Function Details

unsigned short t10crc16	(	const unsigned char *	blk_adr,
		unsigned long	blk_len,
		unsigned short	crc
	)

Calculate the T10 PI CRC guard value for a block.

Code based on Rocksoft's public domain CRC code, refer to http://www.ross.net/crc/download/crc_v3.txt. Minimally altered to work with the ocs_dif API.

Parameters

blk_adr	Pointer to the data buffer.
blk_len	Number of bytes.
crc	Previously-calculated CRC, or crcseed for a new block.

Returns

Returns the calculated CRC, which may be passed back in for partial blocks.
