Function

GLibHashTableforeach

Declaration [src] 

void
g_hash_table_foreach (
  GHashTable* hash_table,
  GHFunc func,
  gpointer user_data
)

Description [src]

Calls the given function for each of the key/value pairs in the GHashTable. The function is passed the key and value of each pair, and the given user_data parameter. The hash table may not be modified while iterating over it (you can’t add/remove items). To remove all items matching a predicate, use g_hash_table_foreach_remove().

The order in which g_hash_table_foreach() iterates over the keys/values in the hash table is not defined.

See g_hash_table_find() for performance caveats for linear order searches in contrast to g_hash_table_lookup().
