Description: Reference for GLib.HashTable.get_keys

### Function

# GLib HashTableget_keys

since: 2.14

#### Declaration

    GList*
    g_hash_table_get_keys (
      GHashTable* hash_table
    )

#### Description

Retrieves every key inside `hash_table`. The returned data is valid until changes to the hash release those keys.

This iterates over every entry in the hash table to build its return value. To iterate over the entries in a `GHashTable` more efficiently, use a `GHashTableIter`.

Available since: 2.14

This function is not directly available to language bindings.

#### Parameters

`hash_table`

  Type: `GHashTable`

  A `GHashTable`.

  The data is owned by the caller of the function.

#### Return value

Type: A list of `gpointer`

A `GList` containing all the keys inside the hash table. The content of the list is owned by the hash table and should not be modified or freed. Use `g_list_free()` when done using the list.

The caller of the function takes ownership of the data container, but not the data inside it.
