DESCRIPTION
       memcached_generate_hash_value() allows you to hash a key using  one  of
       the  hash functions defined in the library. This method is provided for
       the convenience of higher-level language bindings and is not  necessary
       for normal memcache operations.

       Support  for MEMCACHED_HASH_HSIEH is a compile time option that is dis-
       abled by default. To enable tests for this hashing algorithm, configure
       and build libmemcached with the Hsieh hash enabled.

       memcached_generate_hash()  takes  a memcached_st structure and produces
       the hash value that would have been generated based on the defaults  of
       memcached_st.

       As  of  version 0.36 all hash methods have been placed into the library
       libhashkit(3) which is linked with libmemcached(3). For  more  informa-
       tion please see its documentation.

RETURN VALUE
       A  32-bit  integer  which  is the result of hashing the given key.  For
       64-bit hash algorithms, only the  least-significant  32  bits  are  re-
       turned.
