Function Documentation

fletcher16()

uint16_t fletcher16	(	const void *	input_str,
		size_t	num_bytes
	)

Calculate the Fletcher-16 checksum of a block of data.

Parameters

input_str	Pointer to the start of the data block.
num_bytes	Length of the data block, in bytes.

Returns

Note

The Fletcher checksum is an algorithm for computing a position-dependent checksum devised by John G. Fletcher (1934–2012) at Lawrence Livermore Labs in the late 1970s.[1] The objective of the Fletcher checksum was to provide error-detection properties approaching those of a cyclic redundancy check but with the lower computational effort associated with summation techniques.
