  12 =head1 SYNOPSIS
  13
  14   #include <libhashkit/hashkit.h>
  15
  16   uint32_t hashkit_default(const char *key, size_t key_length);
  17   uint32_t hashkit_fnv1_64(const char *key, size_t key_length);
  18   uint32_t hashkit_fnv1a_64(const char *key, size_t key_length);
  19   uint32_t hashkit_fnv1_32(const char *key, size_t key_length);
  20   uint32_t hashkit_fnv1a_32(const char *key, size_t key_length);
  21   uint32_t hashkit_crc32(const char *key, size_t key_length);
  22   uint32_t hashkit_hsieh(const char *key, size_t key_length);
  23   uint32_t hashkit_murmur(const char *key, size_t key_length);

  25   uint32_t hashkit_md5(const char *key, size_t key_length);

  27 =head1 DESCRIPTION
  28
  29 These functions generate hash values from a key using a variety of
  30 algorithms. These functions can be used standalone, or as arguments
  31 to hashkit_set_hash_fn(3) or hashkit_set_continuum_hash_fn(3).
  32
  33 The hashkit_hsieh() is only available if the library is built with
  34 the appropriate flag enabled.
  35
  36 =head1 RETURN VALUE
  37
  38 A 32-bit hash value.
