C hash implementation based on khash.

Install with clib:

$ clib install clibs/hash

hash_t *hash = hash_new();
hash_set(hash, "name", "tobi");
hash_set(hash, "species", "ferret");
hash_set(hash, "age", "2");

hash_each(hash, {
  printf("%s: %s\n", key, (char *) val);
});

hash_free(hash);

yields:

species: ferret
age: 2
name: tobi

The hash type.

void hash_set(hash_t *self, char *key, void *val);

Set key to val.

void *hash_get(hash_t *self, char *key);

Get value for key or NULL.

int hash_has(hash_t *self, char *key);

Check if the hash contains key.

void hash_del(hash_t *self, char *key);

Remove key from the hash.

hash_each(hash_t *self, block)

A macro for iterating key/value pairs.

hash_each(users, {
  printf("%s: %s\n", key, (char *) val);
})

hash_each_key(hash_t *self, block)

A macro for iterating keys only.

hash_each_key(users, {
  printf("%s\n", key);
})
