Function
GLibHashTablesteal_extended
since: 2.58
Declaration [src]
gboolean
g_hash_table_steal_extended (
GHashTable* hash_table,
gconstpointer lookup_key,
gpointer* stolen_key,
gpointer* stolen_value
)
Description [src]
Looks up a key in the GHashTable, stealing the original key and the
associated value and returning TRUE if the key was found. If the key was
not found, FALSE is returned.
If found, the stolen key and value are removed from the hash table without
calling the key and value destroy functions, and ownership is transferred to
the caller of this method, as with g_hash_table_steal(). That is the case
regardless whether stolen_key or stolen_value output parameters are requested.
You can pass NULL for lookup_key, provided the hash and equal functions
of hash_table are NULL-safe.
The dictionary implementation optimizes for having all values identical to
their keys, for example by using g_hash_table_add(). Before 2.82, when
stealing both the key and the value from such a dictionary, the value was
NULL. Since 2.82, the returned value and key will be the same.
