CombineCommutativeSigs()

uint64_t CombineCommutativeSigs	(	uint64_t	h1,
		uint64_t	h2
	)

Commutative hash combination NULL hashes (i.e.

hash value of zero) do not propagate, meaning that the combination of a non-zero hash and a zero hash will yield a non-zero hash.

CombineNonCommutativeSigs()

uint64_t CombineNonCommutativeSigs	(	uint64_t	h1,
		uint64_t	h2
	)

Non-commutative hash combination NULL hashes (i.e.

hash value of zero) do not propagate, meaning that the combination of a non-zero hash and a zero hash will yield a non-zero hash.
