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.

       The allowed hash algorithm constants are listed in the manpage for mem-
       cached_behavior_set().

       memcached_generate_hash()  takes  a  memcached_st struture 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
       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
       returned.
