### Method

# GLib HashTableIterinit

since: 2.16

#### Declaration [src]

    void
    g_hash_table_iter_init (
      GHashTableIter* iter,
      GHashTable* hash_table
    )

#### Description [src]

Initializes a key/value pair iterator and associates it with `hash_table`. Modifying the hash table after calling this function invalidates the returned iterator.

The iteration order of a `GHashTableIter` over the keys/values in a hash table is not defined.

    GHashTableIter iter;
    gpointer key, value;

    g_hash_table_iter_init (&iter, hash_table);
    while (g_hash_table_iter_next (&iter, &key, &value))
      {
        // do something with key and value
      }

Available since: 2.16

#### Parameters

`hash_table`

  Type: `GHashTable`

  A `GHashTable`.

  The data is owned by the caller of the method.
