### Struct

# GLibHashTableIter

since: 2.0

#### Description

    struct GHashTableIter {
      /* No available fields */
    }

A GHashTableIter structure represents an iterator that can be used to iterate over the elements of a `GHashTable`. GHashTableIter structures are typically allocated on the stack and then initialized with g_hash_table_iter_init().

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

Available since: 2.0

#### Instance methods

###### g_hash_table_iter_get_hash_table

Returns the `GHashTable` associated with `iter`.

since: 2.16

###### g_hash_table_iter_init

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

since: 2.16

###### g_hash_table_iter_next

Advances `iter` and retrieves the key and/or value that are now pointed to as a result of this advancement. If `FALSE` is returned, `key` and `value` are not set, and the iterator becomes invalid.

since: 2.16

###### g_hash_table_iter_remove

Removes the key/value pair currently pointed to by the iterator from its associated `GHashTable`. Can only be called after `g_hash_table_iter_next()` returned `TRUE`, and cannot be called more than once for the same key/value pair.

since: 2.16

###### g_hash_table_iter_replace

Replaces the value currently pointed to by the iterator from its associated `GHashTable`. Can only be called after `g_hash_table_iter_next()` returned `TRUE`.

since: 2.30

###### g_hash_table_iter_steal

Removes the key/value pair currently pointed to by the iterator from its associated `GHashTable`, without calling the key and value destroy functions. Can only be called after `g_hash_table_iter_next()` returned `TRUE`, and cannot be called more than once for the same key/value pair.
