NAME

     mi_vector_hash -- fast 32bit hash functions


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <stdlib.h>

     void
     mi_vector_hash(const void * restrict key, size_t len, uint32_t seed,
         uint32_t hashes[3]);


DESCRIPTION

     The mi_vector_hash function computes three 32-bit hash values of the mem-
     ory area starting at key with length len.

     The output is identical on all architectures and only depends on key and
     seed.


IMPLEMENTATION NOTES

     An optimised code path is used if key is aligned on a 32-bit boundary.


HISTORY

     The mi_vector_hash function appeared in NetBSD 6.0.


AUTHORS

     The hash function has been created by Bob Jenkins.
