  48 .SH DESCRIPTION
  49 .sp
  50 \fBmemcached_generate_hash_value()\fP allows you to hash a key using one of
  51 the hash functions defined in the library. This method is provided for
  52 the convenience of higher\-level language bindings and is not necessary
  53 for normal memcache operations.
  54 .sp
  55 The allowed hash algorithm constants are listed in the manpage for
  56 \fBmemcached_behavior_set()\fP.
  57 .sp
  58 \fBmemcached_generate_hash()\fP takes a \fBmemcached_st\fP struture
  59 and produces the hash value that would have been generated based on the
  60 defaults of the \fBmemcached_st structure\fP.
  61 .sp
  62 As of version 0.36 all hash methods have been placed into the library
  63 libhashkit(3) which is linked with libmemcached(3). For more information please see its documentation.
  64 .SH RETURN
  65 .sp
  66 A 32\-bit integer which is the result of hashing the given key.
  67 For 64\-bit hash algorithms, only the least\-significant 32 bits are
  68 returned.
