NAME

memcached_generate_hash_value - Hash a key value

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.
