NAME

memcached_generate_hash_value - Hash a key value

CONTENTS

LIBRARY

C Client Library for memcached (libmemcached, -lmemcached)

SYNOPSIS



  #include <memcached.h>

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

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



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.

The allowed hash algorithm constants are listed in the manpage for memcached_behavior_set().

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

As of version 0.36 all hash methods have been placed into the library libhashkit(3) which is linked with libmemcached(3).

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.
