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 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 fuctions 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.

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.
