NAME

       memcached_generate_hash_value - Generating hash values directly

       Hash a key value

SYNOPSIS

       #include <libmemcached/memcached.h>
              Compile and link with -lmemcachedutil -lmemcached

       uint32_t     memcached_generate_hash_value(const    char    *key,    size_t    key_length,
       memcached_hash_t hash_algorithm)

              Parameterskey -- the key to generate a hash of

                     • key_length -- the length of the key without any terminating zero

                     • hash_algorithm -- memcached_hash_t, the algorithm to use

              Returns
                     a 32 bit hash value

       uint32_t memcached_generate_hash(memcached_st *ptr, const char *key, size_t key_length)

              Parametersptr -- pointer to an initialized memcached_st struct

                     • key -- the key to generate a hash of

                     • key_length -- the length of the key without any terminating zero

              Returns
                     a 32 bit hash value

DESCRIPTION

       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.

       Support for MEMCACHED_HASH_HSIEH is a compile time option that is disabled by default.  To
       enable  tests  for this hashing algorithm, configure and build libmemcached with the Hsieh
       hash enabled.

       memcached_generate_hash() takes a memcached_st structure and produces the hash value  that
       would have been generated based on the defaults of memcached_st.

       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.

RETURN VALUE

       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.
