Function
GLibHashTablelookup_extended
Declaration [src]
gboolean
g_hash_table_lookup_extended (
  GHashTable* hash_table,
  gconstpointer lookup_key,
  gpointer* orig_key,
  gpointer* value
)
Description [src]
Looks up a key in the GHashTable, returning the original key and the
associated value and a #gboolean which is TRUE if the key was found. This
is useful if you need to free the memory allocated for the original key,
for example before calling g_hash_table_remove().
You can actually pass NULL for lookup_key to test
whether the NULL key exists, provided the hash and equal functions of hash_table are NULL-safe.

- value
- 
            Type: gpointer*Return location for the value associated with the key. The argument will be set by the function. The argument can be NULL.
