find

Calls the given function for key/value pairs in the #GHashTable until @predicate returns true. 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).

Note, that hash tables are really only optimized for forward lookups, i.e. g_hash_table_lookup(). So code that frequently issues g_hash_table_find() or g_hash_table_foreach() (e.g. in the order of once per every entry in a hash table) should probably be reworked to use additional or different data structures for reverse lookups (keep in mind that an O(n) find/foreach operation issued for all n values in a hash table ends up needing O(n*n) operations).
