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.
