\fI\%memcached_generate_hash_value()\fP allows you to hash a key using one of
95
the hash functions defined in the library. This method is provided for
96
the convenience of higher\-level language bindings and is not necessary
97
for normal memcache operations.
99
The allowed hash algorithm constants are listed in the manpage for
100
\fBmemcached_behavior_set()\fP.
102
\fI\%memcached_generate_hash()\fP takes a \fBmemcached_st\fP struture
103
and produces the hash value that would have been generated based on the
104
defaults of \fBmemcached_st\fP.
106
As of version 0.36 all hash methods have been placed into the library
107
libhashkit(3) which is linked with libmemcached(3). For more information please see its documentation.
110
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
