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.
