+.Dt MI_VECTOR_HASH 3
+.Os
+.Sh NAME
+.Nm mi_vector_hash
+.Nd fast 32bit hash functions
+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In stdlib.h
+.Ft void
+.Fn mi_vector_hash "const void * restrict key" "size_t len" \
+ "uint32_t seed" "uint32_t hashes[3]"
+.Sh DESCRIPTION
+The
+.Nm
+function computes three 32-bit hash values of the memory area starting at
+.Fa key
+with length
+.Fa len .
+.Pp
+The output is identical on all architectures and only depends on
+.Fa key
+and
+.Fa seed .
+.Sh IMPLEMENTATION NOTES
+An optimised code path is used if
+.Fa key
+is aligned on a 32-bit boundary.
+.Sh HISTORY
+The
+.Nm
+function appeared in
+.Nx 6.0 .
+.Sh AUTHORS
+The hash function has been created by Bob Jenkins.
