Functions
uint32_t	memhash (const void *data, size_t len)
	Hash data.
uint32_t	memhash_string (const char *s)
	Hash zero-terminated string.
uint32_t	memhash_seed (const void *data, size_t len, uint32_t seed)
	Hash with given seed.

Detailed Description

Randomized in-memory hashing.

Functions here use randomized seed and pick fastest hash for current CPU.

Function Documentation

uint32_t memhash	(	const void *	data,
		size_t	len
	)

Hash data.

uint32_t memhash_string

(

const char *

s

)

Hash zero-terminated string.

uint32_t memhash_seed	(	const void *	data,
		size_t	len,
		uint32_t	seed
	)

Hash with given seed.

Result is not randomized, but still may vary on different CPU-s.
