Functions
uint32_t	biomcmc_hashint_salted (uint32_t a, int salt)
uint32_t	biomcmc_hashbyte_salted (const void *str, size_t size, int salt)
uint64_t	biomcmc_hashint64_salted (uint64_t k, int salt)
uint32_t	biomcmc_hashint_mix_salted (uint32_t a, uint32_t b, int salt)
uint64_t	biomcmc_hashint64_mix_salted (uint64_t a, uint64_t b, int salt)
uint32_t	biomcmc_hashint_64to32_seed (uint64_t x, int seed)
uint32_t	biomcmc_hashint_64to32 (uint64_t key)
uint32_t	bipartition_hash (bipartition bip)
	32bits hash value for bipartition
uint64_t	biomcmc_murmurhash3_128bits (const void *key, const size_t len, const uint32_t seed, void *out)
	murmurhash3 using 64bits to return 128 bits (4 ints) of hash into out[] and also 64 bits as return value The 64bits is the format used internally (for speed), but the input can be a vector of any size (>1 byte)
uint64_t	biomcmc_murmurhash3_64bits (const void *key, const size_t len, const uint32_t seed)
	convenience function for calling mumurhash_128bits without an output vector
uint32_t	biomcmc_murmurhash3_32bits (const void *data, size_t nbytes, const uint32_t seed)
	murmurhash3 using 32bits to return 32 bits of hash as return value
uint64_t	biomcmc_xxh64 (const void *input, const size_t len, const uint32_t seed)
	xxhash function for 64 bits
