This method is provided for the convenience of higher-level language bindings and is not necessary for normal memcache operations. .PP The allowed hash algorithm constants are listed in the manpage for \&\fBmemcached_behavior_set()\fR. .PP \&\fBmemcached_generate_hash()\fR takes a memcached_st struture and produces the hash value that would have been generated based on the defaults of the memcached_st structure. .PP As of version 0.36 all hash methods have been placed into the library \&\fBlibhashkit\fR\|(3) which is linked with \fBlibmemcached\fR\|(3). .SH RETURN .IX Header "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. .SH HOME .IX Header "HOME" To find out more information please check: .SH AUTHOR .IX Header "AUTHOR" Brian Aker, .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBmemcached\fR\|(1) \fBlibmemcached\fR\|(3) \fBmemcached_behavior_set\fR\|(3) \fBlibhashkit\fR\|(3)
