Here is the caller graph for this function:

Write() [1/2]

CSipHasher & CSipHasher::Write	(	const uint8_t *	data,
		size_t	size
	)

Hash arbitrary bytes.

Here is the call graph for this function:

Write() [2/2]

CSipHasher & CSipHasher::Write

(

uint64_t

data

)

Hash a 64-bit integer worth of data.

It is treated as if this was the little-endian interpretation of 8 bytes. This function can only be used when a multiple of 8 bytes have been written so far.
