Detailed Description

This file contains header definitions for the hash functions we use.

The hash functions are public domain (see lookup3.c).

◆ hashword()

uint32_t hashword ( const uint32_t *  k,
size_t  length,
uint32_t  initval 
)

Hash key made of 4byte chunks.

Parameters
kthe key, an array of uint32_t values
lengththe length of the key, in uint32_ts
initvalthe previous hash, or an arbitrary value
Returns
: hash value.

size_t  length,
uint32_t  initval 
)

Hash key data.

Parameters
kthe key, array of uint8_t
lengththe length of the key, in uint8_ts
initvalthe previous hash, or an arbitrary value
Returns
: hash value.

◆ hash_set_raninit()

void hash_set_raninit ( uint32_t  v)
