.SH DESCRIPTION
.sp
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.
.sp
The allowed hash algorithm constants are listed in the manpage for
memcached_behavior_set().
.sp
memcached_generate_hash() takes a memcached_st struture and produces
the hash value that would have been generated based on the defaults
of the memcached_st structure.
.sp
As of version 0.36 all hash methods have been placed into the library
libmemcached(3) which is linked with libmemcached(3).
.sp
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.
