Function
GLibHashTableget_keys_as_array
since: 2.40
Declaration [src]
gpointer*
g_hash_table_get_keys_as_array (
  GHashTable* hash_table,
  guint* length
)
Description [src]
Retrieves every key inside hash_table, as an array.
The returned array is NULL-terminated but may contain NULL as a
key. Use length to determine the true length if it’s possible that
NULL was used as the value for a key.
Note: in the common case of a string-keyed GHashTable, the return
value of this function can be conveniently cast to (const gchar **).
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.
You should always free the return result with g_free().  In the
above-mentioned case of a string-keyed hash table, it may be
appropriate to use g_strfreev() if you call g_hash_table_steal_all()
first to transfer ownership of the keys.
Available since: 2.40
