.SH DESCRIPTION
.sp
\fI\%memcached_generate_hash_value()\fP 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
\fBmemcached_behavior_set()\fP\&.
.sp
\fI\%memcached_generate_hash()\fP takes a \fBmemcached_st\fP struture
and produces the hash value that would have been generated based on the
defaults of \fBmemcached_st\fP\&.
.sp
As of version 0.36 all hash methods have been placed into the library
libhashkit(3) which is linked with libmemcached(3). For more information please see its documentation.
.SH RETURN
.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.
