:relfileprefix: ../../../
:mrdocs:

Load the finalized 128‐bit hash into `hash1` and `hash2`.

== Synopsis

Declared in `<bslh_spookyhashalgorithmimp.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
void
finalize(
    xref:BloombergLP/bslh/SpookyHashAlgorithmImp/Uint64.adoc[Uint64]* hash1,
    xref:BloombergLP/bslh/SpookyHashAlgorithmImp/Uint64.adoc[Uint64]* hash2);
----

== Description

Load the finalized hash into the specified `hash1` and `hash2`. `hash1` will contain the higher order bits of the hash and `hash2` will contain the lower order bits. The internal state of the algorithm will be modified, meaning that calling final multiple times will result in different hash values being returned. The returned hash will be the same as if `Hash128` had been called will all of the accumulated data in one block. The behavior is undefined unless both `hash1` and `hash2` point to 8 bytes of modifiable memory. Note that a value will be returned even if `update` has not been called.

== Parameters

[cols="1,4"]
|===
| Name| Description
| *hash1*
| higher‐order 64 bits of the finalized hash
| *hash2*
| lower‐order 64 bits of the finalized hash
